fix(backups): make cozy-default FoundationDB backup and restore reach S3 - #4901
Makes FoundationDB backup and restore work end to end on the platform-managed cozy-default BackupClass, and binds FoundationDB in it. The shipped cozy-default-foundationdb strategy never reached S3: a chain of independent defects broke it before any byte was written, and restore into a fresh cluster could not run at all. Each fix below was found and confirmed on a live dev stand (operator v2.30.0, FDB 7.3.63, SeaweedFS behind an ACME ingress), by reading the operator and FoundationDB sources at the pinned versions, or with a local docker probe.
Credentials and TLS:
--blob_credentials became ----blob_credentials. The operator prefixes every customParameters entry with -- for the backup_agent, fdbbackup and fdbrestore. The credentials file now reaches both the backup_agent and the operator through FDB_BLOB_CREDENTIALS, and the API doc no longer recommends the broken form.
accountName had no @. The operator's parseAccountName requires one. It is now @<host:port>, so FDB reads both key and secret from the file under the account @<host> (FDB drops the port from the lookup key), which is what the projector writes. Any path or trailing slash in the configured endpoint is dropped, as the projector already does, so it cannot end up in the blob URL host.
No CA. FoundationDB never loads the OS trust store; with secure_connection=1 and no FDB_TLS_CA_FILE every handshake fails. Both the operator and the agent point it at the image's system bundle.
No SNI before 7.3.78 / 7.4.6 (use sni in the tls handshake apple/foundationdb#12374). An SNI-routed ingress aborts the handshake, so 7.3.63 fails with Network connection failed where 7.3.79 reaches HTTP. The operator's init containers (which supply fdbbackup/fdbrestore, picked by major.minor) move to 7.3.79 and 7.4.8, and a new minimumAgentVersions strategy field runs an older cluster's backup_agent at the SNI-capable patch of its minor. Tenant clusters are not upgraded; patch releases of a minor are wire-compatible.
The operator pod had no credentials.cozy-backups-creds is now projected into cozy-foundationdb-operator and mounted there (optional, so the operator starts without the backup stack). The projector skips a listed namespace that does not exist instead of counting a failure every minute.
Backup lifecycle:
bucket_path is not a FoundationDB URL parameter; fdbbackup start rejected the URL. Tenant separation in the shared bucket now comes from the default backup name, <namespace>/<BackupJob>.
The agent pod template was pruned. The driver wrote it to spec.backupDeploymentSpec.podTemplateSpec, which v1beta2 does not have; the operator reads spec.podTemplateSpec.
Readiness read the wrong field.backupDetails.snapshotTime is the snapshot period; restorability is backupDetails.restorable, which BackupJob success now gates on.
restorable never refreshed. The operator reconciles a backup only on generation/annotation changes and does not requeue a reconciled one. The driver bumps an annotation, at most once a minute, on a reconciled but not yet restorable backup.
restorable was pruned by stale CRDs. helm-controller skips CRD upgrades by default, so clusters that took the v2.30.0 bump kept the old schema. The operator source now sets upgradeCRDs: CreateReplace; the schema diff against the CRDs a dev stand carried from before the bump is additive only.
Restore:
Nothing executed the restore.fdbrestore only queues it; backup_agents connected to the destination cluster carry it out, and a fresh cluster has none. The driver now starts agents for the destination with a Stopped FoundationDBBackup rendered from the backup's strategy (owned by the RestoreJob, deleted when the restore completes or fails, with the delete retried before the job is marked Failed). A destination that already has a FoundationDBBackup keeps its own agents and gets none: the operator reads backup state for the whole cluster, so a Stopped object next to a running backup would discontinue it. If every FoundationDBBackup of the destination sets agentCount: 0, the operator runs no agents for it, and the RestoreJob fails at once instead of running out its deadline. The restore's own agents ignore a strategy's explicit agentCount: 0. The controller gains delete on foundationdbbackups.
A RestoreJob that runs out its deadline is marked Failed and its agents are removed, but the queued restore is not aborted (the operator has no abort on FoundationDBRestore deletion, and that path is unchanged from main). Aborting it needs fdbrestore abort against the destination and is left for a follow-up.
Data lifecycle:
Deleted Backups left their data in the shared bucket. Binding FDB into cozy-default sends every tenant's continuous backup to the system bucket, and the FDB branch of the Backup cleanup was a no-op, so retention would grow the bucket without bound. The driver now owns the directory it names per BackupJob, like the Redis and Rabbitmq drivers: deleting the Backup stops and removes the operator-side FoundationDBBackup, then runs a Job with fdbbackup delete in the strategy's agent pod template and waits for it (a directory already gone counts as deleted). Same give-up conditions and backups.cozystack.io/skip-artifact-cleanup escape hatch as Rabbitmq. A strategy that pins backupName shares a directory between runs, and its Backups keep the data; ownership is read from the directory the operator CR actually writes, so changing backupName while a BackupJob runs cannot make a Backup claim a shared directory. The delete Job runs fdbbackup from foundationdb/foundationdb:<agent version>; an image the strategy's pod template sets for the foundationdb container is resolved as the operator resolves it (untagged takes the agent version, tagged or digest-pinned is used as is). An air-gapped install mirrors that image as well. The delete script was exercised in docker against an auth-enforcing SeaweedFS with a real FDB 7.3.79 backup: the first run deleted the directory, a rerun reported success, wrong credentials failed the Job.
Cluster-wide operator status:
A backup could be taken for another one. The operator copies status.backupDetails.url from the cluster-wide fdbbackup status and skips start while that shows a backup running, so a BackupJob reconciled while the previous backup was stopping could report the previous directory as its own. The driver builds the URL from the CR's spec (as the operator's getURL does), records that on the Backup, and treats a backup as ready only when status shows its own directory. Earlier Stopped CRs of the cluster are deleted once their stop is reconciled, so an operator restart cannot reconcile one again and discontinue the running backup.
A new backup could take over the previous one. While the cluster still reports the previous backup running, the operator does not start a new CR's backup but runs fdbbackup modify, moving the previous backup into the new directory. A BackupJob now creates its CR only after every stopped CR of the cluster has been reconciled and no longer shows a backup running, refreshing their status meanwhile; a stopped CR that still shows one is not pruned either.
Overlapping BackupJobs of one cluster: a stopped CR is pruned only once its BackupJob has finished, so a job that is still running cannot recreate its CR and stop the newer backup.
A BackupJob recreated under an earlier name: CRs record the creating job's UID, so a stopped CR from the failed attempt is replaced rather than reused, a Backup of that name that is still being deleted is waited for, and a Backup recording another CR is not adopted.
A stop never ends a backup that is not restorable yet.discontinue waits for a restorable snapshot, so a backup whose agents cannot write would run forever and hold back every later BackupJob of the cluster. A BackupJob that runs out its deadline now has the operator abort its backup: the CR is deleted with the operator's finalizer and a stop deletion policy. cleanup is not used: the operator keeps its finalizer until its own fdbbackup delete succeeds, which never happens for a bucket whose credentials it lacks, so the partial directory of a failed job stays in the bucket. A stopped backup that reported itself not restorable is aborted the same way by the next BackupJob, but only when its job failed or is gone without a Backup; a job that succeeded had a restorable backup, which the stop ends. A BackupJob whose CR a later job stopped before its first snapshot still succeeds: discontinue lets the backup reach a restorable snapshot before ending it, and a stopped CR counts once its own directory is restorable, even before the operator has acted on the stop.
A BackupJob waits while a restore runs into its cluster: the restore runs on a stopped agents CR, which the operator would turn on a backup started next to it if it reconciled that CR again. API errors during the handover are retried within the deadline instead of failing the job, since an earlier pass may already have stopped the cluster's running backup. Nothing else of the cluster runs at those points, so the untagged abort only reaches that backup. The deadline is 45 minutes by default; a BackupClass raises it with the backupTimeout parameter (a Go duration, read as for Kafka) for a database whose first snapshot takes longer. cozy-default itself carries no parameters, so there the deadline stays at 45 minutes; a database that needs longer uses a custom BackupClass.
A BackupJob whose name already has a Backup fails before it stops the cluster's running backup or starts its own, since that Backup's deletion would remove the directory it writes.
Backup deletion uses its own Job rather than the operator's deletionPolicy: cleanup, which on CR deletion aborts whatever backup the cluster reports running. It retries transient credential errors instead of releasing, stops the operator CR even when skip-artifact-cleanup releases the Backup (the next BackupJob prunes it once the stop has gone through), and renders the delete Job with the parameters the backup ran with.
Backup deletion skips the operator wait when the FoundationDB cluster is gone, waits while a RestoreJob still reads the Backup, records a Warning naming the skip annotation on each failed delete, and hashes long Backup names into a valid Job name.
E2E: why the round-trip is gated, as for etcd
Every other backup round-trip in hack/e2e-chainsaw points its S3 client at the in-cluster SeaweedFS (https://seaweedfs-s3.tenant-root.svc:8333) and trusts its self-signed CA, either by copying the CA into the client pod (Redis, RabbitMQ, Kafka, MariaDB, Postgres, ClickHouse via backup.endpointCA) or with insecureSkipTLSVerify (MongoDB, VMInstance). That works because each of those clients runs in a pod the test configures. The bucket's external ingress endpoint that cozy-default uses is the unroutable s3.example.org placeholder in kind.
FoundationDB has a client the test cannot configure: fdbbackup and fdbrestore run inside the cluster-wide FoundationDB operator pod, and its credentials file and CA bundle come from the operator package values. Pointing them at the in-cluster endpoint would mean reconfiguring a platform component from inside a test. That is the etcd situation (its snapshot agent exposes no CA or insecure surface), so this follows the etcd precedent:
foundationdb-2-backup-contracts runs in CI. A BackupJob on cozy-default must produce an operator CR with the job's own <namespace>/<job> directory and an @host account, the SNI-capable agent version and the credentials in spec.podTemplateSpec; the agent pod must get them, and the operator pod its projected credentials and CA. Bytes never reach S3 there, so the test stops at the wiring and removes the CR.
foundationdb-3-backup-roundtrip is gated behind FDB_E2E_S3_ROUNDTRIP=1 and runs on a real cluster: two consecutive BackupJobs in their own directories, a restore of the second into an empty copy with a sentinel key intact, and deleting the first Backup removing only its directory. In CI it exits 0 with the reason in the log, as etcd-2-backup-roundtrip does.
Validation on a dev stand
The final head was validated by running hack/e2e-chainsaw/foundationdb/backup-roundtrip.sh run (the gated round-trip) against a dev stand on the real cozy-default BackupClass, with the controller built from these changes, the operator, strategy, BackupClass and CRDs as this branch renders them, and a publicly-trusted S3 endpoint behind an SNI-routed ingress:
two consecutive BackupJobs reached Succeeded, each in its own <namespace>/<BackupJob> directory;
a RestoreJob of the second into an empty FoundationDB reached Succeeded, and the sentinel key read back byte for byte;
deleting the first Backup removed its directory (fdbbackup describe: does not exist) and left the second's in place;
backup-roundtrip.sh cleanup then deleted the second Backup and its data, and both applications.
The dev stand was restored to its original state afterwards (all modified objects verified identical to their saved copies, HelmReleases resumed).
That run was on the head before the latest rebase. The review fixes since then (directory ownership taken from the CR, failing a restore into an agentless destination, the delete Job image, the accountName host, waiting for the previous backup to stop, same-name BackupJob handover, aborting a backup a stop cannot end, the backupTimeout deadline, waiting for restores, retrying handover errors) are covered by unit tests only.
Not covered here:
The per-app Bucket walk-through in examples/backups/foundationdb backs up, but its restore still needs that bucket's credentials in the operator's FDB_BLOB_CREDENTIALS; the README says so.
Upgrade notes:
The operator Deployment rolls once (init images, env, volume); the FoundationDB operator CRDs are replaced in place.
No data migration is needed: FoundationDB backups could not complete before this change on either the default or a custom strategy, so no existing Backup depends on the old layout. The strategy CRD only gains the optional minimumAgentVersions field. A custom FoundationDB strategy that passes credentials as a --blob_credentials customParameters entry has to move them to FDB_BLOB_CREDENTIALS in its pod template, since the operator prefixes every entry with --.
An admin who overrides backupStorage.systemNamespaces or fdb-operator.extraEnv/volumes/volumeMounts replaces the whole list and must restate the new entries.
Backups made before this change never became restorable on the default strategy, so there is nothing to migrate; custom strategies that left backupName empty now write under <namespace>/<BackupJob>, while existing backups restore from the name recorded on their Backup.
Screenshots
N/A — no UI changes.
Downstream repositories
Walked the trigger map against the diff. The Backup Classes guide now lives only on the website (content/en/docs/next/operations/services/backup-classes.md in cozystack/website), and it still says FoundationDB is not bound by cozy-default. It needs a follow-up once this merges: FoundationDB in cozy-default, how the credentials and CA reach the operator and the backup_agent, the client versions and SNI, restore agents, the backupTimeout parameter, and that deleting a FoundationDB Backup deletes its data. The box stays unticked until then. No other repository matches: the new strategy field is in a platform-internal CRD, and there is no app package, values-schema, variant or Talos change.
No downstream repository is affected by this change
fix(backups): FoundationDB backup and restore now work on the cozy-default BackupClass, which binds FoundationDB. Credentials reach the operator and the backup agents through FDB_BLOB_CREDENTIALS, both trust the system CA bundle, and they run SNI-capable FoundationDB client releases (7.3.79/7.4.8) so SNI-routed S3 endpoints work; tenant clusters are not upgraded. Backups land under <namespace>/<BackupJob> in the bucket, a BackupJob succeeds once the backup is restorable, and a restore starts its own backup agents for the destination cluster. Deleting a FoundationDB Backup taken after this upgrade now deletes its directory from the bucket (annotate the Backup backups.cozystack.io/skip-artifact-cleanup=true to keep the data); older Backups are left alone. The FoundationDB operator CRDs are now upgraded in place.

The pull request connects FoundationDB to the default backup strategy. It updates credential handling, backup readiness and identity, restore-agent management, and owned-directory cleanup. It also adds backup contract checks and an opt-in backup/restore round-trip test.
The FoundationDB strategy adds minimum agent versions and updates its pod-template and parameter contract. The default BackupClass routes FoundationDB to its strategy. Credentials use FDB_BLOB_CREDENTIALS, and account keys use @ followed by the endpoint host without its port. Operator settings add credential and CA mounts, updated monitor image tags, and CRD upgrade configuration.
Backup reconciliation and identity internal/backupcontroller/foundationdbtypes/*, internal/backupcontroller/foundationdbstrategy_controller.go, internal/backupcontroller/foundationdbstrategy_controller_test.go, examples/backups/foundationdb/04-create-backupjob.sh, examples/backups/foundationdb/91-scenario-user-backup.md
Backup details replace SnapshotTime with Restorable. Readiness also checks that the reported URL matches the backup directory. The controller selects agent versions, uses namespace-qualified default directories, refreshes pending status, and prunes eligible stopped backups.
FoundationDB backup deletion waits for active restores and operator-side resource removal. For owned blob-store directories, it creates and polls a cleanup Job. Failed Jobs are removed for retry. The skip annotation leaves the directory in place.
Chainsaw tests validate backup configuration and credentials. An opt-in script checks two backups, restores the second backup, verifies stored data, and confirms deletion of the first backup directory.
FoundationDB backup and restore now work with the default BackupClass. Several lifecycle edge cases remain, including aborting another job's backup at the deadline, leaving a restore CR behind after a restore timeout, and reusing older restore agents. Resolve or accept these before merging.

167-168: Fix the missing failure propagation in describe_dir calls.
state1=$(describe_dir "$uri1") is an assignment with a command substitution. With set -e, a non-zero exit from describe_dir does abort the script, so the failure is not lost. The exit is silent apart from the log_error inside the function. That is acceptable.
The remaining risk is low. If describe_dir returns 2 for the first call, the second call never runs, and the error message already names the cause. No change is needed.
The comment states the inner budgets sum to 6060s, which is about 101m. The margin is thin but valid. Gated runs exit immediately, so there is no CI impact. No change is required.
⚠️Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Handle an empty pod list before reading .items[0].
If no Running cluster_controller pod matches, kubectl get ... -o jsonpath='{.items[0]...}' fails with an index error. With set -e inside $(...) in an assignment, the script exits before the friendly log_error on Line 86 runs. The guard on Line 86 is therefore unreachable for the no-pod case. Add || true so the guard produces the message.

Always set the cleanup image to the recorded agent version.
The code sets c.Image only when the strategy template leaves it empty. A strategy pod template can pin a foundationdb container image, for example a sidecar-style image or an older client. In that case the delete Job ignores foundationdbAgentVersionKey. The constant comment says the Job reuses the agent version because an SNI-routed endpoint needs an SNI-capable client. A pinned older image would fail fdbbackup delete on every run. The Backup would then stay Terminating until someone sets the skip annotation. The operator also replaces the agent image with the version-specific image, so the template image is not the image the agents ran. Override the image every time.

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Verify cancellation before removing agents from a timed-out restore.
When a fresh-cluster restore exceeds its deadline while still running, failFoundationDBRestore removes only the FoundationDBBackup agents before marking the RestoreJob failed. The FoundationDBRestore CR that queues the actual restore task is not deleted or aborted.
The timeout path (foundationdbstrategy_controller.go:1161–1167) calls failFoundationDBRestore(ctx, restoreJob, message) when the deadline is exceeded and the restore state is not Completed. failFoundationDBRestore (lines 1364–1369) deletes FoundationDBRestoreAgents (the FoundationDBBackup CRs) via deleteFoundationDBRestoreAgents, then calls markRestoreJobFailed.
deleteFoundationDBRestoreAgents (lines 1373–1385) removes only the FoundationDBBackup CRs labelled as agents; it does not delete the FoundationDBRestore CR. markRestoreJobFailed delegates to markRestoreJobFailedReason (restorejob_controller.go:283–291), which updates the RestoreJob status to Failed but issues no abort or cleanup of the underlying restore task.
The FoundationDBRestore CR, created by ensureFoundationDBRestore (foundationdbstrategy_controller.go:1207–1265), persists after timeout failure. No fdbrestore abort call or equivalent cancellation is visible in the failure path. FDB persists restore tasks in the database; removing workers does not release the cluster lock without cancellation.
Verify that markRestoreJobFailed or a failure-finalization path aborts the restore task before agents are removed. If not, confirm whether the FoundationDBRestore CR is owner-deleted or garbage-collected when the RestoreJob is marked Failed, or whether a later cleanup path handles it. Otherwise, the destination can remain locked and agents attempting later retries could resume the failed restore.

The shipped cozy-default-foundationdb strategy never reached the blob
store, which is why FoundationDB was left out of cozy-default:
- The operator prefixes every customParameters entry with "--" for the
backup_agent, fdbbackup and fdbrestore alike, so the strategy's
"--blob_credentials=..." reached FDB as "----blob_credentials" and was
rejected.
- The operator requires an "@" in accountName; the strategy rendered a
bare host, so no backup URL could be built.
- FoundationDB never loads the OS trust store: with secure_connection=1
and no FDB_TLS_CA_FILE its TLS context has no CA and every handshake
fails, and the provisioned bucket endpoint is https.
- The operator pod, which runs fdbbackup and fdbrestore itself, had no
credentials at all.
Pass the credentials file through FDB_BLOB_CREDENTIALS in both the

FoundationDB sends TLS SNI only from 7.3.78 and 7.4.6
(apple/foundationdb#12374). The provisioned bucket endpoint is an
ingress that routes by SNI and aborts the handshake without it, so the
7.3.63 binaries the operator ships, and the 7.3.63 backup_agent of a
default cluster, fail with "Network connection failed" before any S3
request.
Bump the operator's init containers, which supply the fdbbackup and
fdbrestore binaries picked by the cluster's major.minor, to 7.3.79 and
7.4.8. Add minimumAgentVersions to the FoundationDB strategy template:
a cluster on an older patch of a listed major.minor runs its
backup_agent at the listed version instead. Patch releases of one minor
are wire-compatible, so this needs no cluster upgrade. The default
strategy lists the same two versions as the operator.

The default FoundationDB strategy separated tenants sharing the system
bucket with a "bucket_path" URL parameter, which FoundationDB does not
know: fdbbackup start rejects the URL with "Backup Container URL
invalid: Unknown URL parameter: 'bucket_path'", so no backup ever
started.
Drop the parameter and make the driver's default backup name
"<namespace>/<BackupJob name>" instead of the bare BackupJob name. The
name becomes the path under the bucket, so same-named BackupJobs of
different tenants no longer share a directory. Backups taken before
keep restoring from the name recorded on their Backup.

…tor reads it
The driver wrote the strategy's backup_agent pod template to
spec.backupDeploymentSpec.podTemplateSpec, a field FoundationDBBackup
v1beta2 does not have. The apiserver pruned it, so the agents never got
the credentials volume or the TLS settings and every blob request failed
with "Network connection failed". The operator reads spec.podTemplateSpec.
The driver also took backupDetails.snapshotTime > 0 as "a snapshot was
written". The operator uses that field for the snapshot period in
seconds; whether the backup can be restored is backupDetails.restorable.
Mirror both fields as the operator defines them and gate BackupJob
success on restorable.

… run
A FoundationDB BackupJob could never succeed and a restore into a fresh
cluster could never finish:
- The operator reconciles a FoundationDBBackup only on generation or
annotation changes and does not requeue a reconciled one, so a backup
that turns restorable after its last reconcile keeps
restorable=false in status. The driver now bumps an annotation, at
most once a minute, on a backup the operator has reconciled but not
yet reported restorable, so the operator re-reads it.
- Clusters that took the v2.30.0 operator bump kept the old CRDs,
because helm-controller skips CRD upgrades by default, and the
apiserver pruned status.backupDetails.restorable. Upgrade the
foundationdb-operator CRDs with CreateReplace; the schema diff is
additive.
- fdbrestore only queues a restore; backup_agent processes connected to
the destination cluster carry it out, and a cluster restored into
fresh has none. The driver now starts agents for the destination with
a Stopped FoundationDBBackup rendered from the backup's strategy
(agents run, no backup starts), owned by the RestoreJob and deleted
once the restore completes or times out. The controller needs delete
on foundationdbbackups for that.

The operator reads backup state for the whole cluster, so the Stopped
FoundationDBBackup a RestoreJob adds for its agents saw a running
backup on the same cluster as its own and discontinued it: an in-place
restore of a cluster with a live backup stopped that backup. A cluster
that already has any FoundationDBBackup also already has agents, so the
driver now starts restore agents only on a destination without one.
A restore that failed after its agents started left them behind, since
a Failed RestoreJob is not reconciled again and only the owner
reference, on deletion, would remove them. Every failure past that point
now deletes the agents first and retries while the delete does not go
through.
Cover the agent and status-refresh wiring at the reconcile level, and
correct the pod template field named in the strategy API doc.

Binding FoundationDB into cozy-default sends every tenant's continuous
backup to the shared system bucket, and deleting a Cozystack Backup
left both the operator-side FoundationDBBackup and the S3 data behind,
so a retention-pruned Plan would grow the bucket without bound.
The driver now owns the directory it names per BackupJob, the way the
Redis and Rabbitmq drivers own their objects. Deleting the Backup stops
and removes the operator-side FoundationDBBackup (which also keeps a
stopped CR from later discontinuing another backup of the cluster),
then runs a Job with `fdbbackup delete` in the strategy's agent pod
template and waits for it. A directory already gone counts as deleted.
The give-up conditions and the skip-artifact-cleanup annotation match
Rabbitmq. A strategy that pins backupName shares one directory between
runs, and its Backups keep the data; Backups record the ownership and
the agent version used for the delete Job's image.
Restore agents now carry the strategy's customParameters, and a
transient API error while preparing them requeues the RestoreJob
instead of failing it.

The operator copies status.backupDetails.url from the cluster-wide
`fdbbackup status`, and it does not start a backup while that status
shows one running. A BackupJob reconciled while the previous backup was
still stopping could therefore report the previous directory as its own,
succeed on that data, and record a URL whose deletion would remove
another Backup's directory. The driver now builds the URL from the CR's
spec, the way the operator does, records that on the Backup, and treats
a backup as ready only when the status shows its own directory. Status
refreshes are requested for any reconciled backup that is not ready, so
the new backup starts once the previous one has stopped.
Earlier FoundationDBBackup CRs of the cluster are deleted once the
operator has acted on their stop: reconciling a stopped CR again, after
an operator restart for example, would discontinue the running backup.
Backup deletion no longer waits for the operator when the FoundationDB
cluster is gone, waits instead while a RestoreJob still reads the
Backup, records a Warning naming the skip annotation on each failed
delete, and hashes long Backup names into a valid Job name instead of
releasing them without deleting.

…each other
Pruning a stopped FoundationDBBackup whose BackupJob was still running
made that job find no CR on its next poll, create a fresh running one
and stop the newer backup, which then did the same in turn until both
jobs hit their deadline. A stopped CR is now pruned only once its
BackupJob has finished.
The Backup cleanup no longer releases a Backup on a transient error
projecting the credentials; it retries, as the job paths do. The
skip-artifact-cleanup annotation still stops and removes the operator
CR, so its agents stop writing into the directory left behind. The
delete Job renders the strategy with the parameters the backup ran
with. Restore agents that the apiserver rejects as invalid or forbidden
now fail the RestoreJob instead of requeueing without a status.

A BackupJob whose CR a newer job had stopped kept polling, and its
status refresh bumped an annotation on that stopped CR every minute.
The operator then reconciled a stopped CR while the cluster showed the
newer backup running, and its stop path discontinued that backup. The
refresh now skips stopped CRs.
Also bring the walkthrough's readiness description in line with the
driver, which waits for restorable rather than snapshotTime.

…ind a gate
foundationdb-2-backup-contracts runs in CI: a BackupJob on cozy-default
must yield an operator CR naming the job's own directory and an "@host"
account, at the SNI-capable agent version, with the credentials in
spec.podTemplateSpec; the agent pod must get them, and the operator pod
its projected credentials and CA. The sandbox has no S3 endpoint the
backup can reach, so it stops at the wiring and tears the CR down.
foundationdb-3-backup-roundtrip drives backup-roundtrip.sh: two
consecutive BackupJobs in their own directories, a restore of the second
into an empty copy with the sentinel intact, and deleting the first
Backup removing only its directory. Like the etcd round-trip it is gated
behind FDB_E2E_S3_ROUNDTRIP=1: fdbbackup and fdbrestore run inside the
cluster-wide operator pod, whose credentials and CA come from the
package values, so a test cannot point them at the in-cluster SeaweedFS
endpoint, and the external one is a placeholder in kind.

A Backup marked its blob-store directory as owned when the strategy,
rendered at artifact time, left backupName empty. A BackupJob reuses
its existing FoundationDBBackup, so an admin who cleared a pinned
backupName while the job ran made the Backup claim the shared pinned
directory, and deleting it would delete data other Backups still read.
Ownership now follows the directory the CR actually writes: the Backup
owns it only when the CR's backupName is the driver-named

A destination that already has a FoundationDBBackup gets no restore
agents from the driver, since a Stopped CR next to a running backup
would discontinue it. When every such CR sets agentCount: 0 the
operator creates no backup_agent Deployment, so the restore was queued

The delete Job used the strategy template's foundationdb image verbatim
whenever one was set. The operator treats an untagged image as a base
and tags it with the agent version, so a mirrored base such as

right version while the delete Job pulled :latest. A tagged or

The operator reads backup state for the whole cluster. A BackupJob
stopped the cluster's previous FoundationDBBackup and created its own in
the same pass, so the operator could reconcile the new CR while the
previous backup still ran: it then skips the start and runs
`fdbbackup modify` instead, moving the previous backup into the new
job's directory. The new job saw its own directory restorable and
succeeded on a directory without a snapshot of its own, and the
previous CR's discontinue then stopped the only running backup.
A new CR is now created only after every stopped CR of the cluster has
been reconciled and no longer shows a backup running; while one still
does, its status is refreshed (nothing of the cluster runs at that
point, so the refresh can only discontinue the backup being stopped).
Pruning leaves such a CR alone for the same reason.
The same handover covers a BackupJob recreated under an earlier name:
CRs record the UID of the job that created them, so a stopped CR left
by the failed attempt is removed instead of reused (a reused one would
never run again), a Backup of that name still being deleted is waited
for, and a Backup that records another CR is not adopted.

A stop runs `fdbbackup discontinue`, which ends a backup only once it
is restorable. A backup that never got there (agents that cannot reach
the endpoint, say) keeps running, and the operator never reconciles
its stopped CR. Since a BackupJob now waits for every stopped backup of
the cluster before starting its own, such a backup held back every
later BackupJob of the cluster, and only a manual `fdbbackup abort`
released it.
A BackupJob that runs out its deadline now has the operator abort its
backup instead of stopping it: the CR is deleted with the operator's
finalizer and a stop deletion policy, or a cleanup policy when the job
named the directory, which also removes the partial data no Backup
records. A stopped CR that went quiet is only deleted, since the
cluster may be running a newer backup by then. A stopped backup that
reported itself not restorable and whose job has finished is aborted
the same way by the next BackupJob of the cluster. Nothing else of the
cluster runs at either point, so the abort, which takes no tag, only
reaches that backup.

- A BackupJob whose name already has a Backup fails before it starts a
backup: the directory is named after the job, and that Backup's
deletion would delete a new backup written there.
- A Backup released with skip-artifact-cleanup only stops its operator
CR. Deleting it at once could hide a backup still running from the
next BackupJob of the cluster, which waits for every stopped backup.
The next BackupJob prunes it once the stop has gone through.
- Restore agents ignore a strategy's explicit agentCount of 0, which
would make the operator start none; the restore then counted its own
agents as an agentless destination and failed.

Confirm backup ownership before aborting.
At deadline, the CR’s status can describe another job’s running backup. The operator’s untagged abort can then stop that backup. With cleanup, it also deletes this job’s directory.
Coordinate the abort with the cluster’s active backup. A status URL check alone is not sufficient because the status can be stale when the operator processes the deletion.

Update the non-quiet deletion path around abortFoundationDBBackup to confirm
ownership against the cluster’s current active backup before aborting; do not
rely solely on the CR’s possibly stale status or issue an untagged abort. Ensure
cleanup only deletes the job directory after its ownership is confirmed,
preserving the existing quiet-backup behavior.

- The deadline for a first restorable snapshot was a fixed 45 minutes.
The first snapshot of a large database can take longer, and since
the deadline now aborts the backup along with its partial data, such
a database could never be backed up. The BackupClass backupTimeout
parameter now raises it, read as for Kafka (the parsing is shared),
and the failure message points at it.
- A BackupJob whose name already has a Backup is refused before it
stops the cluster's running backup, not after, so the refusal no
longer leaves the cluster without one.

- A BackupJob whose CR a later job stopped before its first snapshot
never succeeded: discontinue lets such a backup reach a restorable
snapshot and then ends it, but readiness required the backup to be
running. The job failed on its deadline and left a restorable
directory in the shared bucket that no Backup recorded. A stopped CR
now counts once its own directory is restorable.
- The deadline abort no longer uses the cleanup deletion policy. The
operator keeps its finalizer until its own `fdbbackup delete`
succeeds, which never happens for a bucket whose credentials it
lacks, and every later BackupJob of the cluster would wait on that
CR. The partial directory of a failed job stays.
- A stopped backup is aborted on behalf of the next BackupJob only when
its job failed, or is gone without having recorded a Backup; a job
that succeeded had a restorable backup, which the stop ends.

- The pass that stops the cluster's previous backup no longer goes on
to create the new CR. The wait that follows reads the cache, which
may not show the stop yet, or show the stopped CR as already quiet,
and a CR created then would make the operator move the previous
backup into the new directory. Any backup of the cluster the cache
still shows running also holds the new one back.
- A stopped CR the operator has not acted on is refreshed as well. A
repeated discontinue fails, and the operator then retries the CR only
on its error backoff, which can eat most of the next job's deadline.
- Restore agents get a name derived from the RestoreJob, so a create
repeated over a stale cache collides instead of starting a second
set, and they carry the strategy's encryptionKeyPath like the backup
agents do.

Signed-off-by: Andrey Kolkov <[email protected]>
- A BackupJob no longer starts a backup on a cluster a restore runs
into. The restore runs on a stopped agents CR, and the operator would
discontinue a backup started next to it the next time it reconciled
that CR.
- An API error while handing over the cluster's backup is retried
within the deadline instead of failing the job: an earlier pass may
already have stopped the running backup. A same-named Backup, an
invalid or forbidden request, and the deadline still fail it.
- A stopped CR whose own directory is restorable counts as ready before
the operator has acted on the stop, so a job stopped just before its
deadline is not aborted with a restorable directory.

## What this PR does
The generated HelmReleases leave `spec.upgrade.crds` unset unless the
PackageSource sets `upgradeCRDs`, so helm-controller never replaces a
CRD that a chart ships in `crds/`. keycloak-operator and
foundationdb-operator ship their CRDs that way and set no policy. On a
v1.6.4 cluster that came through earlier releases, the CRDs of both
operators were older than the ones in the v1.6.4 charts. The v1.25.0
ClusterKeycloakRealm schema has no `spec.sessions`, `spec.login` or
`spec.organizationsEnabled`, so the apiserver dropped the session
settings keycloak-configure sets and the operator never applied them to
the realm. Keycloak also rejected the dashboard KeycloakClient with HTTP
400 on that cluster, and replacing the 17 CRDs from the charts and
restarting keycloak-operator cleared it.
This opts both PackageSources into `upgradeCRDs: CreateReplace`, the
policy mongodb-operator, redis-operator and velero already use, and pins
it with a platform test for each. The keycloak-operator change is not
purely additive. v1.32.0 drops the `realm`, `targetRealm` and
`keycloakOwner` fields that v1.25.0 marked deprecated and requires
`realmRef` and `keycloakRef` instead. Every Keycloak object the platform
renders already uses the refs, and each of the 14 CRDs keeps its single
version, so the replace loses nothing the platform relies on and drops
no stored version. A hand-made object that still uses a deprecated field
would lose it on its next write, and that write needs the ref. The
foundationdb-operator CRDs only add fields from v2.13.0 to v2.30.0, plus
a pattern on `perpetual_storage_wiggle_locality`, which the platform
does not set.
helm-controller applies the policy only when it upgrades a release, and
it upgrades only when the release artifact or its values change. A
PackageSource edit changes neither. The PR therefore also gives the
keycloak-operator package a helm-unittest suite, which pins the realm
fields keycloak-configure sets against the ClusterKeycloakRealm CRD the
chart ships and changes the keycloak-operator artifact, so the CRDs are
replaced on the upgrade that brings this change even where nothing else
in the package changes, as on a backport to release-1.6. The platform
release writes the new PackageSource in the same apply that moves
`cozystack-packages` to the new revision, so the policy should reach the
HelmRelease before the new keycloak-operator artifact does. The
foundationdb-operator package does not change here, so its CRDs are
replaced at the next change to that package, and main already carries
one since v1.6.5.
Objects written while the CRDs were stale get the pruned fields back
only when their chart applies them again. For the cozy realm that is the
next keycloak-configure upgrade. On main it comes with the same platform
upgrade, since keycloak-configure changed after v1.6.5, and its
HelmRelease depends on the keycloak-operator one through the oidc
variant. On a branch where keycloak-configure does not change, the realm
keeps its current session limits until it does or until that release is
forced to upgrade.
#4901 adds the same `upgradeCRDs: CreateReplace` to the
foundationdb-operator PackageSource as part of the FoundationDB backup
work, and it changes the foundationdb-operator package as well. The
foundationdb commit here is separate from the keycloak one and does not
depend on it, so it can be dropped if #4901 lands first.
The other packages that ship CRDs only in `crds/` and set no policy are
bootbox, clickhouse-operator, clustersecret-operator,
cozystack-scheduler, external-dns, grafana-operator, kafka-operator and
snapshot-controller. None of their CRDs changed since v1.0.0, or since
the package was added, apart from description text in external-dns, so
no cluster is behind on them today. kafka-operator gets CreateReplace
with the Strimzi move in #4900. gpu-operator replaces its CRDs with its
own pre-upgrade Job, and the remaining packages render their CRDs from
templates or leave them to an operator. Each of the eight will need the
same review and opt-in the next time its CRDs change.
`make -C packages/core/platform test` passes with 58 suites and 287
tests, and `make -C packages/system/keycloak-operator test` passes. With
either PackageSource reverted to main, its suite fails with `unknown
path spec.variants[0].components[0].install.upgradeCRDs`. With the
v1.25.0 ClusterKeycloakRealm CRD in the chart, the keycloak-operator
suite fails all four assertions. The full `hack/helm-unit-tests.sh`
sweep passes.

Two PackageSources under `packages/core/platform/sources/` gain an
install option, three test suites are new, and
`packages/system/keycloak-operator/Makefile` gains the same `test`
target other packages have. Platform `values.yaml`, variants, bundles,
CRDs, `hack/` and the installer are untouched. The website's
`development.md` does not describe per-package test targets, so the
Makefile change needs nothing there, and no website page documents a
manual CRD replace for these operators.
### Release note
```release-note
fix(keycloak, foundationdb): keycloak-operator and foundationdb-operator now replace their CRDs on upgrade. Clusters upgraded from before v1.2.0 kept the v1.25.0 keycloak-operator CRDs, under which the apiserver dropped the Keycloak realm session settings and Keycloak could reject the dashboard client, and clusters upgraded from before v1.6.0 kept the v2.13.0 foundationdb-operator CRDs.
```

What this PR does
Makes FoundationDB backup and restore work end to end on the platform-managed
cozy-defaultBackupClass, and binds FoundationDB in it. The shippedcozy-default-foundationdbstrategy never reached S3: a chain of independent defects broke it before any byte was written, and restore into a fresh cluster could not run at all. Each fix below was found and confirmed on a live dev stand (operator v2.30.0, FDB 7.3.63, SeaweedFS behind an ACME ingress), by reading the operator and FoundationDB sources at the pinned versions, or with a local docker probe.Credentials and TLS:
--blob_credentialsbecame----blob_credentials. The operator prefixes everycustomParametersentry with--for the backup_agent,fdbbackupandfdbrestore. The credentials file now reaches both the backup_agent and the operator throughFDB_BLOB_CREDENTIALS, and the API doc no longer recommends the broken form.accountNamehad no@. The operator'sparseAccountNamerequires one. It is now@<host:port>, so FDB reads both key and secret from the file under the account@<host>(FDB drops the port from the lookup key), which is what the projector writes. Any path or trailing slash in the configured endpoint is dropped, as the projector already does, so it cannot end up in the blob URL host.secure_connection=1and noFDB_TLS_CA_FILEevery handshake fails. Both the operator and the agent point it at the image's system bundle.Network connection failedwhere 7.3.79 reaches HTTP. The operator's init containers (which supplyfdbbackup/fdbrestore, picked by major.minor) move to 7.3.79 and 7.4.8, and a newminimumAgentVersionsstrategy field runs an older cluster's backup_agent at the SNI-capable patch of its minor. Tenant clusters are not upgraded; patch releases of a minor are wire-compatible.cozy-backups-credsis now projected intocozy-foundationdb-operatorand mounted there (optional, so the operator starts without the backup stack). The projector skips a listed namespace that does not exist instead of counting a failure every minute.Backup lifecycle:
bucket_pathis not a FoundationDB URL parameter;fdbbackup startrejected the URL. Tenant separation in the shared bucket now comes from the default backup name,<namespace>/<BackupJob>.spec.backupDeploymentSpec.podTemplateSpec, which v1beta2 does not have; the operator readsspec.podTemplateSpec.backupDetails.snapshotTimeis the snapshot period; restorability isbackupDetails.restorable, which BackupJob success now gates on.restorablenever refreshed. The operator reconciles a backup only on generation/annotation changes and does not requeue a reconciled one. The driver bumps an annotation, at most once a minute, on a reconciled but not yet restorable backup.restorablewas pruned by stale CRDs. helm-controller skips CRD upgrades by default, so clusters that took the v2.30.0 bump kept the old schema. The operator source now setsupgradeCRDs: CreateReplace; the schema diff against the CRDs a dev stand carried from before the bump is additive only.Restore:
fdbrestoreonly queues it; backup_agents connected to the destination cluster carry it out, and a fresh cluster has none. The driver now starts agents for the destination with aStoppedFoundationDBBackup rendered from the backup's strategy (owned by the RestoreJob, deleted when the restore completes or fails, with the delete retried before the job is marked Failed). A destination that already has a FoundationDBBackup keeps its own agents and gets none: the operator reads backup state for the whole cluster, so a Stopped object next to a running backup woulddiscontinueit. If every FoundationDBBackup of the destination setsagentCount: 0, the operator runs no agents for it, and the RestoreJob fails at once instead of running out its deadline. The restore's own agents ignore a strategy's explicitagentCount: 0. The controller gainsdeleteonfoundationdbbackups.FoundationDBRestoredeletion, and that path is unchanged from main). Aborting it needsfdbrestore abortagainst the destination and is left for a follow-up.Data lifecycle:
cozy-defaultsends every tenant's continuous backup to the system bucket, and the FDB branch of the Backup cleanup was a no-op, so retention would grow the bucket without bound. The driver now owns the directory it names per BackupJob, like the Redis and Rabbitmq drivers: deleting the Backup stops and removes the operator-sideFoundationDBBackup, then runs a Job withfdbbackup deletein the strategy's agent pod template and waits for it (a directory already gone counts as deleted). Same give-up conditions andbackups.cozystack.io/skip-artifact-cleanupescape hatch as Rabbitmq. A strategy that pinsbackupNameshares a directory between runs, and its Backups keep the data; ownership is read from the directory the operator CR actually writes, so changingbackupNamewhile a BackupJob runs cannot make a Backup claim a shared directory. The delete Job runsfdbbackupfromfoundationdb/foundationdb:<agent version>; an image the strategy's pod template sets for thefoundationdbcontainer is resolved as the operator resolves it (untagged takes the agent version, tagged or digest-pinned is used as is). An air-gapped install mirrors that image as well. The delete script was exercised in docker against an auth-enforcing SeaweedFS with a real FDB 7.3.79 backup: the first run deleted the directory, a rerun reported success, wrong credentials failed the Job.Cluster-wide operator status:
status.backupDetails.urlfrom the cluster-widefdbbackup statusand skipsstartwhile that shows a backup running, so a BackupJob reconciled while the previous backup was stopping could report the previous directory as its own. The driver builds the URL from the CR's spec (as the operator'sgetURLdoes), records that on the Backup, and treats a backup as ready only when status shows its own directory. Earlier Stopped CRs of the cluster are deleted once their stop is reconciled, so an operator restart cannot reconcile one again and discontinue the running backup.fdbbackup modify, moving the previous backup into the new directory. A BackupJob now creates its CR only after every stopped CR of the cluster has been reconciled and no longer shows a backup running, refreshing their status meanwhile; a stopped CR that still shows one is not pruned either.discontinuewaits for a restorable snapshot, so a backup whose agents cannot write would run forever and hold back every later BackupJob of the cluster. A BackupJob that runs out its deadline now has the operator abort its backup: the CR is deleted with the operator's finalizer and astopdeletion policy.cleanupis not used: the operator keeps its finalizer until its ownfdbbackup deletesucceeds, which never happens for a bucket whose credentials it lacks, so the partial directory of a failed job stays in the bucket. A stopped backup that reported itself not restorable is aborted the same way by the next BackupJob, but only when its job failed or is gone without a Backup; a job that succeeded had a restorable backup, which the stop ends. A BackupJob whose CR a later job stopped before its first snapshot still succeeds: discontinue lets the backup reach a restorable snapshot before ending it, and a stopped CR counts once its own directory is restorable, even before the operator has acted on the stop.backupTimeoutparameter (a Go duration, read as for Kafka) for a database whose first snapshot takes longer.cozy-defaultitself carries no parameters, so there the deadline stays at 45 minutes; a database that needs longer uses a custom BackupClass.deletionPolicy: cleanup, which on CR deletion aborts whatever backup the cluster reports running. It retries transient credential errors instead of releasing, stops the operator CR even whenskip-artifact-cleanupreleases the Backup (the next BackupJob prunes it once the stop has gone through), and renders the delete Job with the parameters the backup ran with.E2E: why the round-trip is gated, as for etcd
Every other backup round-trip in
hack/e2e-chainsawpoints its S3 client at the in-cluster SeaweedFS (https://seaweedfs-s3.tenant-root.svc:8333) and trusts its self-signed CA, either by copying the CA into the client pod (Redis, RabbitMQ, Kafka, MariaDB, Postgres, ClickHouse viabackup.endpointCA) or withinsecureSkipTLSVerify(MongoDB, VMInstance). That works because each of those clients runs in a pod the test configures. The bucket's external ingress endpoint thatcozy-defaultuses is the unroutables3.example.orgplaceholder in kind.FoundationDB has a client the test cannot configure:
fdbbackupandfdbrestorerun inside the cluster-wide FoundationDB operator pod, and its credentials file and CA bundle come from the operator package values. Pointing them at the in-cluster endpoint would mean reconfiguring a platform component from inside a test. That is the etcd situation (its snapshot agent exposes no CA or insecure surface), so this follows the etcd precedent:foundationdb-2-backup-contractsruns in CI. A BackupJob oncozy-defaultmust produce an operator CR with the job's own<namespace>/<job>directory and an@hostaccount, the SNI-capable agent version and the credentials inspec.podTemplateSpec; the agent pod must get them, and the operator pod its projected credentials and CA. Bytes never reach S3 there, so the test stops at the wiring and removes the CR.foundationdb-3-backup-roundtripis gated behindFDB_E2E_S3_ROUNDTRIP=1and runs on a real cluster: two consecutive BackupJobs in their own directories, a restore of the second into an empty copy with a sentinel key intact, and deleting the first Backup removing only its directory. In CI it exits 0 with the reason in the log, asetcd-2-backup-roundtripdoes.Validation on a dev stand
The final head was validated by running
hack/e2e-chainsaw/foundationdb/backup-roundtrip.sh run(the gated round-trip) against a dev stand on the realcozy-defaultBackupClass, with the controller built from these changes, the operator, strategy, BackupClass and CRDs as this branch renders them, and a publicly-trusted S3 endpoint behind an SNI-routed ingress:Succeeded, each in its own<namespace>/<BackupJob>directory;Succeeded, and the sentinel key read back byte for byte;fdbbackup describe: does not exist) and left the second's in place;backup-roundtrip.sh cleanupthen deleted the second Backup and its data, and both applications.The dev stand was restored to its original state afterwards (all modified objects verified identical to their saved copies, HelmReleases resumed).
That run was on the head before the latest rebase. The review fixes since then (directory ownership taken from the CR, failing a restore into an agentless destination, the delete Job image, the
accountNamehost, waiting for the previous backup to stop, same-name BackupJob handover, aborting a backup a stop cannot end, thebackupTimeoutdeadline, waiting for restores, retrying handover errors) are covered by unit tests only.Not covered here:

It needs a follow-up once this merges: FoundationDB incozy-default, how the credentials and CA reach the operator and the backup_agent, the client versions and SNI, restore agents, thebackupTimeoutparameter, and that deleting a FoundationDB Backup deletes its data. The box stays unticked until then. No other repository matches: the new strategy field is in a platform-internal CRD, and there is no app package, values-schema, variant or Talos change.Release note
