SeaweedFS accepts and stores an S3 bucket lifecycle configuration, but only the s3_lifecycle job of its plugin worker applies it, and that job is scheduled by the admin server. Cozystack deployed neither, so a lifecycle rule returned 200 and no object ever expired, on the platform backup bucket and on tenant buckets alike. That also made the documented way to bound backup storage a no-op.
This PR adds the admin server and a worker to Simple and MultiZone SeaweedFS instances, behind a new lifecycle.enabled value that is off by default. A Client instance is unchanged, because its rules are enforced where the instance it connects to runs. The worker registers for s3_lifecycle only, so vacuum, balancing and erasure coding are not started as a side effect. The admin keeps its job state on a 1Gi volume on lifecycle.storageClass, or on the cluster default when that is empty; volume.storageClass is not reused, because in MultiZone it can name a class local to one zone or node. The admin UI is protected by a generated password, because a tenant namespace admits traffic from the whole cluster. The dashboard Role lists the two new WorkloadMonitors.
Enabling the worker alone was not enough on SeaweedFS 4.45. Its chart renders no [grpc.s3] section, so the s3 gateway served its internal gRPC in plaintext while the worker dials it with mTLS, and every lifecycle delete failed the TLS handshake. The section is backported from upstream (seaweedfs/seaweedfs#11157, released in 4.46) as a chart patch, applied with --forward so the next make update stops at the point where the patch must be dropped instead of silently reversing it. The s3 pods are restarted once so they load the section. This also repairs IAM cache propagation between s3 replicas, which failed in the same way, and it applies whether or not lifecycle is enabled.
The data-plane release now retries a failed install or upgrade in place (RetryOnFailure) instead of rolling it back. With the previous default remediation and unlimited retries, an upgrade that waited out its timeout, for example on a tenant quota with no room for the admin volume, rolled back and retried forever, restarting the s3 pods twice per cycle. The worker's hostname anti-affinity is relaxed to a preference so a rollout finishes on a single-node cluster.
Why lifecycle is off by default
The daily walk that SeaweedFS uses to expire objects sends its deletes without an object identity, and the s3 server skips its compare-and-swap when no identity is given; it does not re-check the object's age either. A key overwritten between the walk's listing and the delete loses its new content. This path is unchanged from 4.45 through 4.52 and on upstream master (weed/s3api/s3lifecycle/dailyrun/walker_dispatcher.go, identityMatches in weed/s3api/s3api_internal_lifecycle.go). Backup buckets write unique keys and are barely exposed; a tenant bucket that rewrites a fixed key is. On top of that, turning enforcement on would start applying, on upgrade, every rule that was stored and ignored until now. Both are retention changes an operator should choose, so nothing changes for existing instances until lifecycle.enabled is set. Making it the default again is left to a separate PR that carries object identity on the walk path; upstream report: seaweedfs/seaweedfs#12451.
Turning lifecycle on and off
When lifecycle.enabled is set, rules that have been stored but ignored start applying within minutes, and objects they have already expired are deleted on that first pass, so review existing bucket lifecycle rules first. Set lifecycle.storageClass before enabling, and prefer a replicated class: the class is part of the admin StatefulSet's volume claim template, which cannot change, so changing it while lifecycle is on makes every upgrade of the instance fail until it is reverted. Moving the volume means disabling lifecycle, deleting the admin-data-seaweedfs-admin-0 PVC, changing the class and enabling lifecycle again. Each instance gains two small pods and a 1Gi PVC; when the tenant quota has no room for them, the data-plane release keeps retrying in place until it has.
When lifecycle.enabled is turned off again, the parent release removes the admin credentials Secret while the data-plane release removes the admin StatefulSet only on its own reconcile, shortly after. An admin pod that restarts in that window fails to start on the missing Secret until the StatefulSet is gone; nothing is lost, and the order is left as is. The admin PVC stays until the instance is deleted, and a later re-enable starts the admin with a new password.
Verified on a test cluster with the 4.45 chart: without the backport, the worker found the expired objects and every delete failed with tls: first record does not look like a TLS handshake; with this branch and lifecycle enabled, a rule with a past expiration date removed the matching objects and left the others, both on a manual run and on the first scheduled pass.

No downstream repository is affected by this change
cozystack/website - follow-up needed, not opened yet: operations/services/backup-classes.md (v1.7 and next) advises an S3 lifecycle policy, which the bundled SeaweedFS applies only once lifecycle.enabled is set; the SeaweedFS reference page gains lifecycle.enabled and lifecycle.storageClass from the regenerated README on the next release
The terraform provider does not model the SeaweedFS application, so the new values do not reach it.
Release note
fix(seaweedfs): S3 bucket lifecycle rules can now be enforced. Simple and MultiZone SeaweedFS instances run the SeaweedFS admin server and a lifecycle worker when the new `lifecycle.enabled` value is set; it is off by default, so existing instances keep their current behaviour. It stays off by default because the upstream daily expiry walk deletes without checking that the object it listed is still the one stored, so an object overwritten in that window can be deleted although it is new. When enabled, rules that were stored but ignored start applying within minutes and objects they have already expired are deleted on that first pass; review existing rules first. Each enabled instance gains two small pods and a 1Gi volume, placed on `lifecycle.storageClass` or the cluster default. Independently of the switch, the s3 gateway now serves its internal gRPC over mTLS, which repairs IAM cache propagation between s3 replicas and restarts the s3 pods once on upgrade.
Summary by CodeRabbit
New Features
Added optional, daily S3 bucket lifecycle-rule processing for supported SeaweedFS configurations. It is disabled by default; Client instances rely on lifecycle rules configured on the connected SeaweedFS.
Added configurable storage for lifecycle job state and dashboard visibility for lifecycle components.
Enabled the S3 gRPC server to use its internal TLS identity when security is configured.
Bug Fixes
Improved storage-class handling so numeric-looking names remain strings and unset classes are omitted where appropriate.
Clarified backup cleanup guidance, including when lifecycle rules apply and how to reclaim storage.
weed s3 takes its gRPC server identity from [grpc.s3] in security.toml
and serves plaintext when the section is missing, which it is in the
4.45 chart. Every peer dials that port with mTLS: the s3_lifecycle
worker with its [grpc.worker] certificate, other s3 replicas with
[grpc.client] for IAM cache propagation. Both fail the handshake, so
lifecycle deletes cannot run and identity changes do not reach the
other replicas.
The section is backported from upstream (seaweedfs/seaweedfs#11157,
first released in 4.46) as a chart patch. It uses the internal
CA-signed client certificate the s3 pods already mount, not the public
listener's tlsSecret, which internal peers would not trust.
security.toml is mounted by subPath, so a running s3 pod never sees the
new section. A pod annotation changes the s3 template in this release
so the upgrade restarts it.

SeaweedFS accepts and stores a bucket lifecycle configuration, but only
the s3_lifecycle job of its plugin worker acts on it, and that job is
scheduled by the admin server. Neither ran here, so a rule returned 200
and no object ever expired, on the platform backup bucket and on tenant
buckets alike, and the documented way to bound backup storage did
nothing.
Both now run in Simple and MultiZone instances, behind lifecycle.enabled
(on by default). A Client instance has no data plane of its own; its
rules are enforced where the master it connects to runs. The worker
registers for s3_lifecycle alone, so enabling lifecycle does not also
start vacuum, balancing or erasure coding. The admin keeps its job state
on a small volume (on volume.storageClass when set), and its UI gets a
generated password, because a tenant namespace admits traffic from the
whole cluster and the server is unauthenticated without one. The
data-plane chart keeps both off unless its parent turns them on, so it
never starts an admin without that password.
Existing rules start applying minutes after the upgrade: the admin's
scheduler runs the first pass within one idle cycle of its lifecycle
lane, then once a day, and objects the rules have already expired are
deleted on that first pass.

The notes that send a tenant to a bucket lifecycle rule for a backup
object Cozystack leaves behind read as if some policy were already in
place. None is: the rule has to be set on the bucket, and it is applied
only by an object store that implements lifecycle, which the bundled
SeaweedFS now does once a day while lifecycle.enabled is on.

Walkthrough
The changes add optional SeaweedFS bucket-lifecycle processing, configure S3 gRPC TLS, and update storage-class rendering in SeaweedFS charts. Backup documentation now describes lifecycle cleanup conditions for different object stores.
The charts expose lifecycle.enabled and lifecycle.storageClass. The documentation describes lifecycle processing, its Client-topology behavior, and storage requirements. Backup notes describe when lifecycle rules apply and how to reclaim unpruned objects.
System chart lifecycle workloads packages/system/seaweedfs/values.yaml, packages/system/seaweedfs/tests/lifecycle_test.yaml
The chart adds admin and worker settings for the s3_lifecycle job. Tests check rendered resources, storage, credentials, resource settings, and disabled behavior.
Extra chart lifecycle configuration packages/extra/seaweedfs/templates/*, packages/extra/seaweedfs/tests/lifecycle_test.yaml
The chart conditionally configures admin and worker components, creates or reuses admin credentials, and renders workload monitors. Tests cover lifecycle settings, credentials, storage class, monitors, dashboard access, and release retry strategy.
The security configuration sets the S3 gRPC certificate and key paths. The update target applies the patch in forward-only mode, the S3 pod template receives a TLS configuration annotation, and tests check the rendered configuration and annotation.
The templates quote configured storage-class values. PVC templates omit storageClassName when the corresponding value is unset, where specified. Tests cover numeric-looking values and additional quoted or multiline values.
cozystack/cozystack#2622: Both changes modify the SeaweedFS application schema, including the master.volumeSizeLimitMB configuration contract.
cozystack/cozystack#5224: Both PRs concern cleanup of stored backup archives; this PR documents SeaweedFS lifecycle cleanup.
cozystack/cozystack#5034: Both PRs change backup documentation, including the object-retention and lifecycle-cleanup guidance.

Add coverage that fails on a constant admin password.
The new-instance credential test checks only that data.adminPassword is at least 40 characters. A fixed value of that length passes. No assertion in the suite checks that the value differs between renders. A change from random generation to a fixed value would not fail the suite.
A notEqual check against one literal does not close this gap. It rejects only that literal, so another fixed value still passes. A single helm-unittest case renders the template once and cannot compare two generations.
The existing-Secret test covers only the lookup path, so it does not cover generation for a new instance.

[P1] Preserve object identity on the lifecycle walk path
An expired unversioned key can be overwritten after the walker lists it but before the delete RPC. The worker then deletes the fresh replacement. Evidence: the 4.45 walker sends ExpectedIdentity as nil. The server identity check accepts that unconditionally. It then deletes the live unversioned object without reevaluating its age. Please backport identity validation for the walk path and add an overwrite regression test before starting this worker.
The reason will be displayed to describe this comment to others. Learn more.
Confirmed against upstream: walker_dispatcher.go builds the request with ExpectedIdentity nil (L59-L67, byte-identical in 4.45, 4.52 and current master), identityMatches returns true for a nil witness, and the unversioned and suspended branches of lifecycleDispatch delete without re-checking the rule, while the event path in dispatch.go does send identity. Rather than start the worker over that path, lifecycle.enabled now defaults to false (the data-plane chart already kept the admin and the worker off unless the parent turns them on), so nothing changes for existing instances and the race is reachable only on an instance where an operator opts in. The values comment, the field description and the release note state the race and that on-by-default comes back only with identity on the walk path. Carrying identity in a patched image is left to a separate PR with the overwrite regression test you asked for, and the upstream report is seaweedfs/seaweedfs#12451. Does keeping it opt-in until then work for you?

Verdict: NOT LGTM
The diagnosis and the mechanism (admin + worker + the [grpc.s3] backport) are correct, and the worker is scoped cleanly. The blocker is that lifecycle.enabled defaults ON and changes data retention on upgrade.
[CRITICAL] default-ON expires objects on the first pass after upgrade, over an upstream delete race
With the default on, every Simple and MultiZone instance starts applying lifecycle rules that were stored but ignored before, within minutes of the upgrade, and deletes objects they have already expired on the first pass. On top of that, SeaweedFS's cold-start walk sends ExpectedIdentity nil, the server skips the CAS on nil, and deletes the unversioned object without re-evaluating its age, so a key overwritten between the listing and the delete RPC is removed fresh. That nil path is unchanged through 4.52 upstream. For backup buckets (unique timestamp keys) the race barely hits, but for tenant buckets that overwrite a "latest" key it does. A silent retention change on upgrade should be opt-in (lifecycle.enabled: false by default) until identity is carried on the walk path, or at minimum gated behind an explicit per-upgrade acknowledgement.
[MAJOR] rollback loop under a full tenant quota flaps the data plane
seaweedfs-system sets upgrade.remediation.retries: -1 with no strategy, so Flux defaults to rollback. On a tenant whose quota is already full, the new admin PVC/pod cannot schedule, helm waits its timeout, Flux rolls back, retries, and loops. Each cycle toggles the grpc-s3-tls annotation and the ConfigMap, so the s3 pods roll twice per cycle and the data plane flaps. Your own external tenant->seaweedfs HR already uses RetryOnFailure for exactly this reason; the internal HR should too. The PR body's "the data-plane release waits until it has room" does not match this behaviour.
[MINOR] the [grpc.s3] patch has no removal marker
The backport is byte-for-byte correct, but there is no "remove at >= 4.46" marker on the patch or in the Makefile. On the next chart bump, BSD /usr/bin/patch (macOS) reverse-applies it silently and drops the section, returning plaintext gRPC. Add a marker, or lean on s3_grpc_tls_test.yaml to catch it.
Credit: admin password is generated (randAlphaNum 40) and persisted, the admin stays ClusterIP with ingress disabled behind mTLS, and the worker registers for s3_lifecycle only, so vacuum/balancing/EC are not started as a side effect.
The admin volume and the two lifecycle pods are new demands on tenant
quota, so an upgrade into a namespace with no headroom can wait out its
timeout. Flux's default remediation then rolls the release back, and
with unlimited retries it does so on every attempt: each rollback drops
the [grpc.s3] section and the s3 restart annotation, each retry brings
them back, and the s3 pods restart twice per cycle until quota frees up.
RetryOnFailure keeps what was applied and retries it, as the parent
release that the apiserver builds for the application already does.

The backport becomes redundant once the vendored chart reaches 4.46.
Re-applied to a chart that already carries the section, BSD patch takes
it as reversed, removes the section and exits 0, so a re-vendor would
quietly return the s3 gRPC listener to plaintext. --forward refuses an
already-applied patch with a non-zero exit, which stops the update at
the point where the patch should be dropped.

The worker is a one-replica Deployment, so a rollout surges a second
pod before stopping the first, and the subchart pins worker pods apart
with a hard hostname anti-affinity. On a single-node cluster the surge
pod never schedules and the release waits out its timeout on every
change to the worker template. A preference keeps the spread where
there are nodes for it, as the master and s3 settings here already do.

The daily walk that expires objects sends its deletes without an object
identity, and the s3 server skips its compare-and-swap when none is
given (walker_dispatcher.go and identityMatches, unchanged from 4.45
through 4.52). It does not re-check the object's age either, so a key
overwritten between the walk's listing and the delete loses its new
content. Backup buckets write unique keys and barely meet that window;
a tenant bucket that rewrites a fixed key does.
Turning enforcement on by default would also start applying, on
upgrade, every rule that was stored and ignored until now. Both are
retention changes an operator should choose, so the admin server and
the worker now run only where lifecycle.enabled is set. On by default
can return once the walk carries identity.

volume.storageClass is picked for volume server data, and in a
MultiZone instance it can name a class whose volumes exist in one zone
or on one node. Reusing it for the admin volume would tie the admin to
that zone or node, so losing it would stop lifecycle enforcement for
the whole instance, a placement nobody chose for the admin. The admin
volume now takes lifecycle.storageClass, and the cluster default when
that is empty.

Leaving this as is. helm-unittest renders each case once and has no way to compare two renders, so the suggested test cannot be written in this framework; the generation is a single randAlphaNum 40 call, and the test that matters for operation, that an existing password survives a re-render, is in place.
Thanks, all three are handled on the latest push. CRITICAL: lifecycle.enabled now defaults to false, so an upgrade neither starts applying stored rules nor exposes tenant buckets to the walk-path delete race; the field description, the values comment and the release note say why, and on-by-default is left to a follow-up that carries identity on the walk path (upstream report: seaweedfs/seaweedfs#12451). MAJOR: the internal data-plane HelmRelease now uses RetryOnFailure for install and upgrade, with a unit test, so a release waiting on tenant quota retries in place and no longer rolls the [grpc.s3] section and the s3 restart annotation back and forth; the body no longer claims the release simply waits. MINOR: the Makefile applies the backport with --forward next to a note to drop it once the vendored chart carries [grpc.s3] (4.46), so a re-vendor onto 4.46 stops with a non-zero exit instead of BSD patch reversing it silently, and s3_grpc_tls_test.yaml still pins the section. Also changed on the way: the admin volume takes its own lifecycle.storageClass instead of volume.storageClass, the dashboard Role lists the admin and worker monitors, and the worker's hostname anti-affinity is a preference so it rolls out on a single node.
The worker is no longer started by default: lifecycle.enabled defaults to false, details in the thread on seaweedfs.yaml. Identity on the walk path is left to a separate PR (upstream report: seaweedfs/seaweedfs#12451).

Verdict
Request changes
Most of this holds up well. The vendored security-configmap.yaml edit that the lint flags is a legitimate re-vendor, not a hand edit: reversing patches/s3-grpc-tls.patch off it yields the upstream-shaped file and re-applying reproduces the committed bytes, and the patch is wired into the Makefile with --forward so it fails loudly once upstream ships the section. The topology matrix is consistent, the admin credential Secret stays internal, the tests are green and non-vacuous, and live CI including the in-tree E2E passes. One confirmed issue is worth fixing before merge, plus a couple of smaller robustness gaps.
Confirmed: the new storageClass interpolation is YAML-injectable
lifecycle.storageClass is interpolated unquoted and its schema entry is a plain type: string with no pattern, so a crafted value escapes the field and writes arbitrary keys into the system HelmRelease's values, past the values.schema.json that is supposed to be the tenant-facing control surface. I rendered it: a value carrying a newline and an indented image: block lands image.repository as a sibling of admin under spec.values.seaweedfs. SeaweedFS is a tenant-creatable app, so the author of the CR is the one who can do this. The blast radius is that instance's own namespace, and I did not prove a node or cross-tenant escape, but it does defeat the schema as an input gate.
The same unquoted shape already exists at volume.storageClass, so this isn't newly introduced, it's one more instance of a pattern worth closing. Quoting the interpolation fixes it; the pool and zone sites a few lines up are already quoted, so this is just bringing these two in line. A pattern on both schema fields would belt-and-suspenders it.
What's correct
The gRPC-TLS backport points [grpc.s3] at the client CA cert that the s3 pods actually mount, so the handshake has a cert to find.
helm unittest passes 54/54 (extra) and 94/94 (system), the guard-parity bats 10/10, and the suites still pass after merging current main. The Go change is a comment reword with no logic.
The admin password Secret is not exposed through the cozyrd, and the dashboard Role only adds read-only WorkloadMonitors bound to tenant super-admin.

[MAJOR] Unquoted storageClass interpolation is YAML-injectable
lifecycle.storageClass is interpolated unquoted here, and its schema entry is a plain type: string with no pattern. A crafted value escapes the field and writes arbitrary keys into the system HelmRelease's values, past the values.schema.json that is meant to gate tenant input. Rendered proof: setting storageClass to a value carrying a newline plus an indented image: block lands image.repository: evil/pwned as a sibling of admin under spec.values.seaweedfs. SeaweedFS is a tenant-creatable app, so the CR author can do this.
The blast radius is that instance's own namespace and I did not prove a node or cross-tenant escape, so this isn't a confirmed isolation break, but it does defeat the schema as an input gate. The identical unquoted shape already lives at volume.storageClass (seaweedfs.yaml:263), so it isn't newly introduced, it's one more instance of the same pattern. The pool and zone sites just above (seaweedfs.yaml:282, 298, 323) are already quoted. Fix: {{ . | quote }} here and at :263, and ideally a pattern on both schema fields.

Fixed. Both interpolations into the system HelmRelease values are quoted now, lifecycle.storageClass here and volume.storageClass at :263, so a value with a line break stays inside its own field. lifecycle.storageClass is new in this PR, so it also carries the StorageClass name rules in its schema (maxLength: 253 and the DNS-1123 subdomain pattern), and the same payload is refused when the application is written. I left volume.storageClass without a pattern: it is an existing field, and a pattern there would start refusing values already stored in existing applications. Tests: tests/volume_storage_class_test.yaml (line break stays in its field, numeric name stays a string) and the two refuses a storage class ... cases in tests/lifecycle_test.yaml. The same class of defect sat in three neighbouring places, fixed here as well: the pool and zone classes were wrapped in quotes by hand, so a quote character in the value broke the release values, and they now use quote; db.storageClass went unquoted into the database release and its CNPG Cluster, and is quoted at both steps.

[MINOR] bad storageClass values fail without a legible signal
Two smaller gaps on the same field, both fixed by quoting and/or a schema guard. A numeric-looking value like "123" renders storageClass: 123 (int) into the admin StatefulSet's volumeClaimTemplate, which the apiserver would reject (not executed, no cluster). lifecycle: null makes the render fail with an opaque template error rather than a readable message. And a typo'd class passes the schema, leaves the admin PVC Pending, and because the class sits in an immutable volumeClaimTemplate, every later upgrade of the instance fails with only the README describing the disable-delete-re-enable recovery, no render-time guard pointing at it.

The numeric case is fixed through both charts, see the reply to lexfrei below. A value that cannot name a StorageClass is now refused by the schema with at '/lifecycle/storageClass': ... does not match pattern, instead of an opaque render error or a pending claim. Two parts I left as they are. lifecycle: null fails with a nil pointer error, the same as volume: null or any other section set to null in this chart; guarding one section would not change that for the rest, so it is better handled for the chart as a whole if at all. A class name that is valid but does not exist cannot be detected at render time without a cluster lookup, and the chart does not look up StorageClasses anywhere; the README describes the recovery, and the field description says to set the class before enabling lifecycle.

scooby87 NOT LGTM. Keeping lifecycle off by default addresses my previous concern about starting the unsafe walker on upgrade.
The storage class still needs quoting in both charts. Evidence: lifecycle.storageClass: "123" passes schema validation and both renders, but the admin StatefulSet contains storageClassName: 123, which native Kubernetes decoding rejects as a number instead of a string. Quoting the parent interpolation at packages/extra/seaweedfs/templates/seaweedfs.yaml:390 fixes that hand-off, but the vendored admin template emits the field unquoted again. Please preserve the string through both stages and cover this case in the existing Helm tests.
The volume and admin storage classes were written unquoted into the
values of the data-plane release. A class name made only of digits,
which Kubernetes allows, arrived there as a number, and a value with a
line break could add keys next to the field, past the schema that is
the tenant's input gate. Both are now quoted. lifecycle.storageClass,
new in this release, also carries the StorageClass name rules in its
schema, so a value that cannot name a class is refused when the
application is written instead of leaving the admin claim pending.

The upstream admin and volume StatefulSets write storageClassName
unquoted, so a class name made only of digits, which Kubernetes allows
and the parent chart now hands on as a string, turned back into a
number there and the claim was rejected. The field is quoted, and left
out when no class is named: quoting an empty value would set an empty
storageClassName, which disables dynamic provisioning instead of using
the cluster default. Upstream 4.52 and master still write both fields
unquoted, so this is a chart patch, applied with --forward so make
update stops once upstream carries an equivalent change.

The master, filer, volume index, log and all-in-one claims of the
upstream chart write storageClassName unquoted, like the data claims
did, so a class name made only of digits renders as a number and the
claim is rejected. None of them is set by Cozystack today, but they
are values of the same chart that a later change can start handing on,
and the patch already exists for the data claims. They follow the same
rule: quoted, and left out when no class is named so that the cluster
default applies. The deprecated filer.enablePVC claim is left alone:
it renders only with filer.data unset, and the template fails earlier on
an unset filer.data, so it cannot be reached.

Pool and zone storage classes were wrapped in quotes by hand, which
does not escape a quote or a backslash in the value: a quote closes the
string early and the data-plane release values stop parsing, with a
YAML error that does not name the field. They are now quoted like the
volume and admin classes.

db.storageClass went unquoted into the values of the database release
and again into its CNPG Cluster. A class name made only of digits,
which Kubernetes allows, became a number that the Cluster rejects, and
a line break in the value could add keys to the database release
values. It is quoted at both steps.

Verdict
LGTM
Re-reviewed against the five things I raised across the earlier rounds, and all of them are closed on this head.
The default-on retention change is gone: lifecycle.enabled now defaults to false, so the expiry pass is opt-in, and the overwrite-during-walk race is spelled out in the field description.
The rollback loop is fixed: seaweedfs-system now sets strategy: RetryOnFailure, so a release that cannot schedule under a full quota waits in place instead of rolling back and flapping the data plane.
The gRPC-TLS patch carries a removal marker now, and the Makefile applies it with patch --forward, so a future chart bump that already has [grpc.s3] fails loudly instead of silently reverse-applying.
The storage-class YAML injection is closed twice over: every interpolation is quoted, in the extra chart and the vendored admin and volume templates, and the schema carries a pattern that rejects a value with a newline in it.
The bad-value handling comes with it, since the quoting and the pattern cover the numeric and injection shapes together.
Tests pass, and the vendored edit reproduces byte-for-byte from the patch. Good to merge from my side.

scooby87 LGTM. I reran the numeric storage-class case through both charts and native Kubernetes decoding. Removing the quoting at either stage makes the existing string assertion fail, and restoring it makes the test pass. Lifecycle remains off by default, with the upstream overwrite risk documented for operators who enable it. The required checks, including E2E, are green on this head.
Fixed in both stages. The parent chart now hands lifecycle.storageClass and volume.storageClass to the data-plane release quoted, and a new chart patch, patches/storage-class-string.patch, quotes storageClassName in the upstream admin and volume StatefulSets, and in the master, filer, index, log and all-in-one claims of the same chart, which Cozystack does not set today. The patch leaves the field out when no class is named, because a quoted empty value would set storageClassName: "" and disable dynamic provisioning instead of using the cluster default. Upstream 4.52 and master still write these fields unquoted, so it is applied with --forward and make update stops once upstream carries an equivalent change. Tests for "123" on each stage: hands a numeric storage class name on as a string in both parent test files, keeps a numeric admin storage class name a string and keeps a numeric volume storage class name a string in the system chart, plus the empty case for each claim. Rendering the parent's HelmRelease values through the system chart gives storageClassName: "123" as a string.

What this PR does
SeaweedFS accepts and stores an S3 bucket lifecycle configuration, but only the
s3_lifecyclejob of its plugin worker applies it, and that job is scheduled by the admin server. Cozystack deployed neither, so a lifecycle rule returned 200 and no object ever expired, on the platform backup bucket and on tenant buckets alike. That also made the documented way to bound backup storage a no-op.This PR adds the admin server and a worker to Simple and MultiZone SeaweedFS instances, behind a new
lifecycle.enabledvalue that is off by default. A Client instance is unchanged, because its rules are enforced where the instance it connects to runs. The worker registers fors3_lifecycleonly, so vacuum, balancing and erasure coding are not started as a side effect. The admin keeps its job state on a 1Gi volume onlifecycle.storageClass, or on the cluster default when that is empty;volume.storageClassis not reused, because in MultiZone it can name a class local to one zone or node. The admin UI is protected by a generated password, because a tenant namespace admits traffic from the whole cluster. The dashboard Role lists the two new WorkloadMonitors.Enabling the worker alone was not enough on SeaweedFS 4.45. Its chart renders no
[grpc.s3]section, so the s3 gateway served its internal gRPC in plaintext while the worker dials it with mTLS, and every lifecycle delete failed the TLS handshake. The section is backported from upstream (seaweedfs/seaweedfs#11157, released in 4.46) as a chart patch, applied with--forwardso the nextmake updatestops at the point where the patch must be dropped instead of silently reversing it. The s3 pods are restarted once so they load the section. This also repairs IAM cache propagation between s3 replicas, which failed in the same way, and it applies whether or not lifecycle is enabled.The data-plane release now retries a failed install or upgrade in place (
RetryOnFailure) instead of rolling it back. With the previous default remediation and unlimited retries, an upgrade that waited out its timeout, for example on a tenant quota with no room for the admin volume, rolled back and retried forever, restarting the s3 pods twice per cycle. The worker's hostname anti-affinity is relaxed to a preference so a rollout finishes on a single-node cluster.Why lifecycle is off by default
The daily walk that SeaweedFS uses to expire objects sends its deletes without an object identity, and the s3 server skips its compare-and-swap when no identity is given; it does not re-check the object's age either. A key overwritten between the walk's listing and the delete loses its new content. This path is unchanged from 4.45 through 4.52 and on upstream master (
weed/s3api/s3lifecycle/dailyrun/walker_dispatcher.go,identityMatchesinweed/s3api/s3api_internal_lifecycle.go). Backup buckets write unique keys and are barely exposed; a tenant bucket that rewrites a fixed key is. On top of that, turning enforcement on would start applying, on upgrade, every rule that was stored and ignored until now. Both are retention changes an operator should choose, so nothing changes for existing instances untillifecycle.enabledis set. Making it the default again is left to a separate PR that carries object identity on the walk path; upstream report: seaweedfs/seaweedfs#12451.Turning lifecycle on and off
When
lifecycle.enabledis set, rules that have been stored but ignored start applying within minutes, and objects they have already expired are deleted on that first pass, so review existing bucket lifecycle rules first. Setlifecycle.storageClassbefore enabling, and prefer a replicated class: the class is part of the admin StatefulSet's volume claim template, which cannot change, so changing it while lifecycle is on makes every upgrade of the instance fail until it is reverted. Moving the volume means disabling lifecycle, deleting theadmin-data-seaweedfs-admin-0PVC, changing the class and enabling lifecycle again. Each instance gains two small pods and a 1Gi PVC; when the tenant quota has no room for them, the data-plane release keeps retrying in place until it has.When
lifecycle.enabledis turned off again, the parent release removes the admin credentials Secret while the data-plane release removes the admin StatefulSet only on its own reconcile, shortly after. An admin pod that restarts in that window fails to start on the missing Secret until the StatefulSet is gone; nothing is lost, and the order is left as is. The admin PVC stays until the instance is deleted, and a later re-enable starts the admin with a new password.Verified on a test cluster with the 4.45 chart: without the backport, the worker found the expired objects and every delete failed with
tls: first record does not look like a TLS handshake; with this branch and lifecycle enabled, a rule with a past expiration date removed the matching objects and left the others, both on a manual run and on the first scheduled pass.Screenshots
