What this PR does

Refs #5205.

The S3 endpoint the platform backups use is copied twice, and neither copy is refreshed after publishing.host changes. The COSI sidecar writes BucketInfo once per BucketAccess, so the credentials Secret bucket-cozy-backups-system-credentials rendered from it keeps the old endpoint. The Velero BSL and the default Strategy CRs keep whatever endpoint the last render of backupstrategy-controller saw. The default objects gate only acted on missing objects, so backups kept going to the old host and nothing reported it.

The gate now also forces a render when a copy is stale:

  • the bucket's <bucket>-system release, when the credentials Secret's endpoint differs from the COSI Secret it is rendered from;
  • backupstrategy-controller, when the endpoint an object was rendered with differs from the credentials Secret's. The chart stamps the rendered endpoint on the BSL and on every default Strategy as backups.cozystack.io/endpoint, because the endpoint itself sits at a different path in every kind. Objects without the annotation count as stale until a render stamps it; MinForceInterval bounds the forces.

Stale credentials are forced before the BackupClass and the routed objects are read, so an absent BackupClass or an unreadable Strategy still fails the check but does not keep the old endpoint in the credentials Secret. A BucketInfo without an endpoint is not compared, since rendering from it would write an empty endpoint or fail the bucket release. Repairing missing objects keeps working while the credentials comparison is stale or fails, and a systemSecretName that is not derived from a COSI Secret (no -credentials suffix, or the raw COSI Secret itself) is not compared at all. RBAC is unchanged: the controller already holds cluster-wide get on Secrets. No new metric: nothing would consume it.

What this does not do: the COSI Secret still holds the endpoint the BucketAccess was granted with, so after a host change the endpoint follows only once an operator deletes the BucketAccess and forces bucket-cozy-backups to recreate it (this issues new S3 keys). From there the gate replaces the remaining manual steps of the recovery described in the issue. Automatic re-grant is left for a separate issue, and the operator runbook goes to the website, hence Refs rather than Fixes.

Known limitation: the credentials comparison runs only when backupStorage.systemSecretName is bucket-<bucketName>-system-credentials, the Secret the forced bucket-<bucketName>-system release renders. If an operator sets bucketName and systemSecretName inconsistently, the comparison is switched off rather than forcing a release that never rewrites the compared Secret, so a stale endpoint in that Secret is not repaired. Repairing a missing credentials Secret still forces the release derived from bucketName, as before this PR.

Tested with unit tests for the gate (including the comparison normalisation shared with the chart helpers), helm-unittest for the annotation and the wiring, and a bats guard that every rendered Strategy CR and the BSL carry the annotation. On a live cluster, a server-side render of the chart produced exactly the annotation the gate derives from the real credentials Secret, so the steady state does not force anything.

Release note

fix(backups): the backup controller now re-renders the Velero BSL, the default backup strategies and the platform bucket's credentials Secret when their S3 endpoint is stale, so after the platform bucket's BucketAccess is re-granted for a new publishing.host, backups move to the new endpoint without forcing releases by hand.

Summary by CodeRabbit

  • New Features
    • Backup strategies and storage locations now record their storage endpoint, enabling detection and repair of outdated endpoint settings after bucket access changes.
    • Bucket credentials and backup objects are refreshed independently when their endpoints are missing or out of date.
  • Documentation
    • Clarified when endpoint changes trigger updates and how suspended releases are handled.

…nt changes

The S3 endpoint the platform backups use is copied twice and neither
copy is refreshed. The COSI sidecar writes BucketInfo once per
BucketAccess, so the credentials Secret rendered from it keeps its
endpoint, and the Velero BSL and the default Strategy CRs keep whatever
endpoint the last render of backupstrategy-controller saw. The default
objects gate only acted on objects that were missing, so after a
publishing.host change every backup kept going to the old host with
nothing reporting it.

The gate now also forces a render when a copy is stale: the bucket's
<bucket>-system release when the credentials Secret's endpoint differs
from the COSI Secret it is rendered from, and backupstrategy-controller
when the endpoint an object was rendered with differs from the
credentials Secret's. That endpoint sits at a different path in every
kind, in some only as a bare host, so the chart stamps the rendered
value on each object as backups.cozystack.io/endpoint and the gate
compares that. Objects rendered before the annotation existed count as
stale until one forced render has gone through, which stamps it.

The COSI Secret itself still holds the endpoint the BucketAccess was
granted with; it follows a host change only once the BucketAccess is
re-granted.

Walkthrough

The chart now renders endpoint annotations on default backup objects and supplies COSI Secret configuration to the controller. DefaultObjectsGate checks credentials and object endpoints, then can force the associated HelmRelease when it detects drift.

Changes: Backup endpoint reconciliation

Layer / File(s) Summary
Render and configure backup endpoints
cmd/backupstrategy-controller/main.go, packages/system/backupstrategy-controller/templates/*, packages/system/backupstrategy-controller/tests/*, hack/backupstrategy-crd-gate.bats
Default Strategy and Velero BackupStorageLocation templates add the endpoint annotation. The deployment passes the COSI Secret name when the configured credentials Secret name matches the expected bucket credentials name. Chart tests check endpoint annotations and Secret-name configuration.
Detect and repair endpoint drift
internal/backupcontroller/default_objects_gate.go, internal/backupcontroller/default_objects_gate_test.go, packages/system/backupstrategy-controller/values.yaml, packages/system/bucket/templates/user-credentials.yaml
DefaultObjectsGate checks credentials and backup-object endpoint values, tracks missing and stale entries, and can force the associated releases independently. Tests cover endpoint comparisons, release selection, throttling, and error cases. Documentation describes the endpoint-drift checks.

Explanation

The title "fix(backups): re-render the default backup objects when the S3 endpoint changes" matches the main change. The changeset makes DefaultObjectsGate force a re-render when the endpoint annotations on default Strategy CRs, the Velero BSL, or the platform bucket credentials Secret no longer match the endpoint the chart would render. It adds the backups.cozystack.io/endpoint annotations to the chart templates. The title is specific and uses the conventional commit format. It does not name the COSI Secret or the credentials comparison, but it does not need to cover every detail.

the BucketInfo parsing flow to skip the stale check when the normalized COSI
endpoint is empty; preserve the existing comparison and stale-result behavior
for non-empty endpoints.
- Around line 568-573: Update the renderForced state used by staleEndpoint so it
reflects successful completion of the forced render, not just a successful
HelmRelease patch. Continue marking objects without endpoint annotations stale
until that render completes, and preserve repair behavior when the render fails.
- Around line 386-391: Update the Check flow around the BackupClass Get to apply
force to any stale credentials endpoint identified by staleCredentials before
attempting that read, using only the source Secret and COSI Secret for the
credentials comparison. Preserve the existing BackupClass error handling while
ensuring a failed Get does not prevent releasing stale credentials.

Review comments at
@packages/system/backupstrategy-controller/templates/deployment.yaml:
- Around line 95-97: Update the BACKUP_CREDENTIALS_COSI_SECRET_NAME condition in
the deployment template so it is rendered only when the trimmed systemSecretName
matches backupStorage.bucketName, while preserving the existing “-credentials”
suffix check. This ensures endpoint comparisons apply only to the Secret managed
by the forced release.

scooby87 NOT LGTM. Please make the credentials refresh independent of the object checks. Evidence: I ran regression cases with a newer COSI endpoint and stale source credentials, first with a missing BackupClass, then with a forbidden read of the CNPG Strategy. Both returned an error without patching the credentials HelmRelease (default_objects_gate.go:386–406). An unreadable Strategy therefore keeps the old credentials endpoint in place for the other drivers too. Please force the bucket release before those reads and cover these cases in the gate tests.

Verdict: comment (gate logic is sound; one CI item to confirm before merge)

The endpoint-staleness gate is a sound render-witness design: the backups.cozystack.io/endpoint annotation is stamped by the same helper that fills the spec fields, and the gate recomputes it with the same normalisation, so it compares what each object was rendered with against the live credentials Secret. Repairing missing objects still works when the comparison is stale or fails, so the original gate purpose does not regress.

One CI item and two minor points:

  • E2E (in-tree) is red on the head, on chainsaw/bucket. The tenant-bucket writes in that test actually succeeded (cap1/cap2/cap3 PUT and rm OK), which points at the documented mc/S3 timing shape the test itself references (#4268) rather than this change, but the exact failing assertion is not pinned here. Since this PR changes the system bucket's credentials and endpoint rendering, please confirm a green re-run before merge rather than assume the flake.
  • [MINOR] renderForced stops counting un-annotated objects as stale until a controller restart, but the only case that leaves an object un-annotated after a requested force is a force that failed, which is exactly what the growing force count was meant to surface. Prefer counting always and leaning on MinForceInterval, or read the HelmRelease status.
  • [MINOR] the forced credentials release name is derived from backupStorage.bucketName, the COSI Secret name from trimSuffix "-credentials" systemSecretName, and the lookup from systemSecretName. Inconsistent values force the wrong release. Deriving the COSI name from bucketName with the same formula, or validating equality, removes the footgun.

Thanks. On renderForced: I took the first option. The flag is gone, an object without the endpoint annotation counts as stale on every check until a render stamps it, and MinForceInterval bounds the forces, so a failed forced render keeps showing up in the force counter instead of going quiet until a restart. On the release name: the COSI Secret name is now derived from bucketName with the same formula as the forced release, and the comparison is enabled only when systemSecretName is bucket-<bucketName>-system-credentials, so inconsistent values disable the comparison rather than force the wrong release. The values reference states the same condition. On E2E: E2E (in-tree) passed on the current head.

Thanks, reproduced both cases. The bucket release is now forced before the BackupClass and Strategy reads, and TestCheckForcesStaleCredentialsWhenObjectsUnreadable covers a missing BackupClass and a forbidden CNPG Strategy read: the check still returns the error and counts one check error, but the credentials HelmRelease is forced, the credentials Secret is reported as stale, and the gate's own release is not forced without a conclusive object check.

scooby87 NOT LGTM. The previous credentials-refresh blocker is fixed; my remaining request concerns only a commit message.

Please remove or explain the reason for the "Also mirror the endpoint helper ... and describe the stale endpoint case in the gate's docs, metric help and log lines" paragraph in commit ef0d35e2f553. Evidence: that paragraph lists changes, while the contributing guide requires commit bodies to explain why they are needed. This paragraph was already present in the head I reviewed before; I missed it then.

…ved from COSI

backupStorage.systemSecretName may name a Secret the bucket chart does
not render from a COSI Secret: the raw COSI Secret itself, which the
projector accepts, or any Secret without the -credentials suffix. The
COSI Secret name was then the source name unchanged, so the gate
compared a Secret with itself and either reported it stale on every
tick or failed the check, and stopped repairing missing default objects
as well. Skip the comparison when there is no distinct COSI Secret or
no endpoint key to compare.

The gate compares the annotation with what the chart's endpoint
helper renders, and the helper renders a present but blank endpoint as
a bare https:// instead of falling back, so the gate has to compute
the same value or its expectation and the chart disagree for that
Secret. The gate's docs, metric help and log lines named only missing
objects, so they did not cover a stale endpoint they now report.

…s lag

The credentials comparison returned early when the credentials Secret
was stale or the COSI Secret could not be read, so a missing default
Strategy or BSL was no longer created on that tick, nor on any later
one while the bucket release stayed suspended, kept failing, or the
COSI Secret stayed unreadable. Repairing missing objects is what the
gate did before the comparison existed, and it does not depend on the
answer.

Run the object check on every tick and force each release for what it
renders, reporting a comparison error alongside instead of in place of
the repair.

…are unreadable

The credentials endpoint comparison needs only the credentials Secret and
the COSI Secret it is rendered from, yet its forced render was issued only
after the BackupClass and every routed object had been read. A missing
BackupClass or one unreadable Strategy therefore kept the old endpoint in
the credentials Secret, which the projector hands to every driver, not
just the one whose object failed.

…no endpoint

A BucketInfo without an endpoint differs from every credentials Secret
that has one, so the gate forced the bucket release on every throttle
window. That render cannot converge: an empty endpoint would be written
into the Secret every driver reads, and with the key absent the
template's trimPrefix fails and parks the release in Failed.

…cket's Secret

The gate forces bucket-<bucketName>-system, which renders the
credentials Secret of that bucket's system user and nothing else. The
COSI Secret name was derived from systemSecretName instead, so a value
naming another bucket's Secret made a lagging endpoint there force the
platform bucket release every throttle window without ever refreshing
the Secret that was compared.

…ation

An object without backups.cozystack.io/endpoint stopped counting as
stale as soon as one forced render had been requested, whether or not
that render succeeded. A failed upgrade left the objects unannotated
and the gate silent until the controller restarted, which also hid the
climbing force counter meant to report exactly that failure. Such an
object now stays stale until a render stamps it; MinForceInterval
already bounds the cost.

## What this PR does

Refs #5205.

The S3 endpoint the platform backups use is copied twice, and neither
copy is refreshed after `publishing.host` changes. The COSI sidecar
writes `BucketInfo` once per `BucketAccess`, so the credentials Secret
`bucket-cozy-backups-system-credentials` rendered from it keeps the old
endpoint. The Velero BSL and the default Strategy CRs keep whatever
endpoint the last render of `backupstrategy-controller` saw. The default
objects gate only acted on missing objects, so backups kept going to the
old host and nothing reported it.

The gate now also forces a render when a copy is stale:

- the bucket's `<bucket>-system` release, when the credentials Secret's
endpoint differs from the COSI Secret it is rendered from;
- `backupstrategy-controller`, when the endpoint an object was rendered
with differs from the credentials Secret's. The chart stamps the
rendered endpoint on the BSL and on every default Strategy as
`backups.cozystack.io/endpoint`, because the endpoint itself sits at a
different path in every kind. Objects without the annotation count as
stale until a render stamps it; `MinForceInterval` bounds the forces.

Stale credentials are forced before the BackupClass and the routed
objects are read, so an absent BackupClass or an unreadable Strategy
still fails the check but does not keep the old endpoint in the
credentials Secret. A `BucketInfo` without an endpoint is not compared,
since rendering from it would write an empty endpoint or fail the bucket
release. Repairing missing objects keeps working while the credentials
comparison is stale or fails, and a `systemSecretName` that is not
derived from a COSI Secret (no `-credentials` suffix, or the raw COSI
Secret itself) is not compared at all. RBAC is unchanged: the controller
already holds cluster-wide `get` on Secrets. No new metric: nothing
would consume it.

What this does not do: the COSI Secret still holds the endpoint the
`BucketAccess` was granted with, so after a host change the endpoint
follows only once an operator deletes the `BucketAccess` and forces
`bucket-cozy-backups` to recreate it (this issues new S3 keys). From
there the gate replaces the remaining manual steps of the recovery
described in the issue. Automatic re-grant is left for a separate issue,
and the operator runbook goes to the website, hence `Refs` rather than
`Fixes`.

Known limitation: the credentials comparison runs only when
`backupStorage.systemSecretName` is
`bucket-<bucketName>-system-credentials`, the Secret the forced
`bucket-<bucketName>-system` release renders. If an operator sets
`bucketName` and `systemSecretName` inconsistently, the comparison is
switched off rather than forcing a release that never rewrites the
compared Secret, so a stale endpoint in that Secret is not repaired.
Repairing a missing credentials Secret still forces the release derived
from `bucketName`, as before this PR.

Tested with unit tests for the gate (including the comparison
normalisation shared with the chart helpers), helm-unittest for the
annotation and the wiring, and a bats guard that every rendered Strategy
CR and the BSL carry the annotation. On a live cluster, a server-side
render of the chart produced exactly the annotation the gate derives
from the real credentials Secret, so the steady state does not force
anything.

## What this PR does

Backports to `release-1.7` from `main`, picked by the rules of the
[backport
policy](https://github.com/cozystack/cozystack/blob/main/docs/release/backports.md)
in merge order. A merged pull request comes as its own commits, picked
with `git cherry-pick -x` so each keeps its author, message and
sign-offs, and a merge commit that carries the original's merge message
with a `Backported-from:` trailer naming it; a squash-merged one comes
as one pick. `backport-batch verify` checks that shape. A pick listed as
changed differs from the commit it came from; `git range-diff
<merge>^1..<merge>^2 <batch merge>^1..<batch merge>^2` shows how. A
conflict or a failing check here is a [backport
task](https://github.com/cozystack/cozystack/blob/main/docs/release/backport-tasks/README.md).

### Release note

```release-note
fix(backupstrategy-controller): the ClickHouse (Altinity) and RabbitMQ backup strategy Pods now run a dedicated `backup-http-client` image (alpine + curl + jq + ca-certificates, non-root, ~7 MB) instead of the 349 MB `platform-migrations` image. Air-gapped mirrors need the new `ghcr.io/cozystack/cozystack/backup-http-client` repository.

fix(e2e): a chainsaw assert in the e2e suites keeps polling through a transient API error such as an etcd leader change, instead of failing the suite long before its timeout.

fix(ci): use GITHUB_TOKEN to start the initial packages build when freezing a release line

fix(etcd): the tenant etcd alert etcdHighNumberOfFailedGRPCRequests now counts only the gRPC codes that the etcd mixin and the platform copy of the alert count, so the Canceled watch streams of a Kubernetes API server that stops no longer fire it on every etcd member.

fix(tcp-balancer): HAProxy now takes its fd and thread caps from the replica's memory and CPU limits instead of the node, so a t1.nano balancer is no longer OOMKilled on nodes with many CPUs. maxconn follows the memory limit at about 16 connections per MiB, 2035 on t1.nano, and the pods roll once on upgrade.

fix(kubernetes): the Proxmox cloud-controller-manager now runs v0.16.1, and the Proxmox CCM and CSI driver images are pinned by digest. The v0.15.0 tag referenced before was re-pushed upstream to a build that panics on start, which left every new Proxmox worker with the uninitialized taint.

fix(marketplace): a tapped repository is pinned to a digest instead of following a mutable tag, so moving the tag upstream no longer changes what runs in the cluster; connect accepts oci://...@sha256:... and an optional keyless cosign verify policy (anchored to an exact identity and preserved across re-connects), and with verify flags the CLI verifies the signature and pins the verified digest at tap time.

fix(dashboard): tenant name in the tenant list links to its detail page now (where Delete is), and top level tenants get their Edit button back.

fix(cilium): the IPAM migration hook no longer fails with "Argument list too long" on clusters with more than a few nodes, which blocked the cilium upgrade and every package that depends on networking.

fix(kubernetes): the OIDC bootstrap Job no longer fails to start for a tenant cluster with about 240 or more oidc.users, the bindings now come from a ConfigMap the Job mounts.

fix(clickhouse): a RestoreJob now restores the archive its Backup was taken as, not the newest one. New Backups record the archive name, Backups taken before this release are restored best effort from the newest archive stamped no later than their takenAt, with a warning in the restore pod log. A ClickHouse BackupJob created again under a name whose Backup still exists now fails instead of reporting that Backup as its result.

fix(backups): the backup controller now re-renders the Velero BSL, the default backup strategies and the platform bucket's credentials Secret when their S3 endpoint is stale, so after the platform bucket's BucketAccess is re-granted for a new publishing.host, backups move to the new endpoint without forcing releases by hand.

fix(securitygroups): a SecurityGroup with attachments and no rules no longer leaves an invalid CiliumNetworkPolicy behind; its backing policy is now accepted by Cilium and still allows or denies nothing.

fix(postgres): the init script renders the declared databases in a stable order, so an upgrade that leaves the databases unchanged no longer rewrites the init-script Secret.

fix(mariadb-operator): the MariaDB operator now uses the platform's networking.clusterDomain instead of a hard-coded cozy.local, so replication and User/Database/Grant reconciliation work on clusters with a non-default cluster domain.

fix(redis): an instance with `replicas: 1` now runs one Sentinel instead of three, without a Sentinel PodDisruptionBudget; on upgrade, the PDB the operator created earlier is deleted. Instances with two replicas or more are unchanged.

fix(lineage, kubernetes): the virt-launcher pods of Kubernetes worker nodes are now resolved to their Kubernetes application and marked as managed by Cozystack, so a SecurityGroup attached to a Kubernetes cluster now applies to its worker nodes, not only to its control plane.

fix(api): tenant quota admission now counts the parent pool's usage of extended resources and hugepages, so a child tenant can no longer get a share the parent has already used. After upgrading, updates to existing tenants may be rejected if their quota for these resources exceeds the parent's remaining budget. This includes updates that leave the quota unchanged.

fix(postgres): a Postgres BackupJob now fails as soon as its CloudNativePG Backup fails, with the recorded error, instead of after 30 minutes, and a BackupJob waiting on a CloudNativePG Backup reports a WaitingForCNPGBackup condition with the Backup's phase.

fix(postgres): databases now refuses the PostgreSQL system databases postgres, template0 and template1, and the init job never runs DROP DATABASE on them. A system database a previous version took over is handed back to the superuser on the next upgrade (event trigger removed, ownership and public schema restored, its <db>_admin and <db>_readonly roles dropped). A release that declares one of them must remove the entry before upgrading.

fix(mariadb): a MariaDB BackupJob or RestoreJob whose operator Job failed now ends Failed instead of Succeeded, and a failed backup no longer creates a Ready Backup without an archive. Backups created by failed runs before this fix are not removed; restoring from one can fail or select another dump from the shared prefix.

fix(kubernetes, monitoring): the vmagent of tenant Kubernetes clusters now writes to the tenant's vminsert and labels series with the owning tenant instead of `cozy-monitoring`. Previously no tenant cluster metric reached the tenant's Monitoring.
