fix(cozy-lib): delete the Secrets cert-manager writes when an app is deleted - #4875
Addresses #4704. Deleting an app left the Secrets cert-manager wrote for it in the tenant namespace, private keys included, because cert-manager runs with enableCertificateOwnerRef: false and nothing else deletes them. This PR deletes them for every app where that happens and makes the E2E run fail a suite that still leaves one behind. It also takes in #4876, closed so that the check lands together with the fix it checks.
Seven commits.
fix(cozy-lib) adds cozy-lib.hooks.deleteSecrets, a post-delete hook (ServiceAccount, Role, RoleBinding, Job) that an app feeds with the Secret names its Certificates can write, and wires qdrant, redis, rabbitmq, nats and opensearch to it. Of the other apps that mint their own CA and leaf, mariadb, kubernetes (Talos PKI) and etcd already delete those Secrets in their own hooks.
fix(apps) covers the Secrets of Ingress certificates. harbor, bucket and bootbox get theirs from cert-manager's ingress-shim. The harbor and bucket hooks deleted that Certificate but not its Secret, and bootbox had no hook at all. harbor and bucket now delete the Secret right after the Certificate, and bootbox uses the cozy-lib hook, which takes an optional certificates list for this case. Tenant monitoring and seaweedfs already delete theirs.
fix(cozy-lib) makes the hook accept only Kubernetes resource names, because it writes them into its shell script inside double quotes.
fix(bucket) makes the bucket hook fail whenever its UI TLS Secret may remain, instead of only warning.
fix(cozy-lib) cuts the names of the hook objects to 63 characters, because the apps API admits release names of up to 53 and a Job name goes into the 63-character job-name label of its pods.
fix(cozy-lib) builds the hook image with cozy-lib.image, so the cluster images registry applies, and adds _hooks.tpl to the Renovate manager that refreshes the clastix/kubectl digest.
How the cleanup works.
Delete is granted by explicit resourceNames. cert-manager stamps its Secrets only with the cluster-wide controller.cert-manager.io/fao label, so a label sweep would reach sibling apps in the namespace.
An empty list, a blank entry or a value that is not a list fails rendering, because an RBAC rule without resourceNames grants delete on every Secret in the namespace. So does any entry that is not a Kubernetes resource name, because the names go into the Job's shell script inside double quotes, where $ and a backquote are still expanded.
A failed delete exits non-zero, so the Job and its log stay instead of being collected by hook-succeeded. A Secret that is already gone is not a failure. The bucket hook still only warns about leftover ACME objects, as it did before, but now fails whenever its Secret may remain.
The hooks render whatever the TLS values are, so a release that had TLS on earlier and off at uninstall is cleaned too. None of these apps accepts a user-provided Secret under those names.
A Certificate that the release does not render itself, which is every ingress-shim Certificate, is deleted before its Secret, and a failure there leaves the Secret alone. cert-manager issues the Secret of a live Certificate again, with a new ACME order where the issuer is ACME. cert-manager v1.20 puts no finalizer on a Certificate (it sets one only on ACME Challenges), so the Certificate is gone once its delete returns.
How the guard works.
A Secret is charged to the suite when, after the suite's own cleanup, it carries the cert-manager.io/certificate-name annotation, was created at or after the suite started, and the root of its chain was too. A Secret with no owners of its own is walked as if the Certificate the annotation names owned it, then up that Certificate's ownerReferences like a pod. A platform Secret re-issued mid-suite traces back to a Certificate the install created and is not charged, and one whose Certificate is gone is. A Secret an operator patched an owner onto, like the PerconaServerMongoDB ones, is walked through that owner.
Charged Secrets get the same 300s budget and the same kubectl wait --for=delete as pods, and are reported under their own LEAKED-SECRETS marker and leaked-secrets annotation with the Certificate and root of each. The pod markers are unchanged. The allowlist stays per suite and covers both kinds.
The read is kubectl get secrets --field-selector type=kubernetes.io/tls, cut to metadata inside the pipe from kubectl, so it does not carry every stored Helm release revision along and the keys never reach a shell variable.
Why not the global flag. enableCertificateOwnerRef: true would change the same behaviour for every Certificate the platform issues, the CA Certificates of its own components among them, and a Certificate removed or renamed in a platform chart would take its key with it. A per-Certificate owner reference is not available either, as spec.secretTemplate in cert-manager v1.20 carries labels and annotations only.
E2E criterion, registered before the run. Every suite prints leak-guard: suite=<dir> clear after, or a LEAKED-SECRETS line carrying allowlisted=, checked-once= or inconclusive=, and no line matches LEAKED-SECRETS suite=.* budget=. Without the two fixes, reading the charts and suites on main, the guard fails qdrant, redis and opensearch, redis for redis-secure and for redis-flip, whose refused TLS upgrade still creates Certificates. That is the leak the first two commits remove. harbor, bucket and bootbox cannot show theirs in E2E, because the sandbox never completes an ACME order.
Testing.
helm unittest 1.1.2 passes for qdrant (112), redis (74), rabbitmq (109), nats (81), opensearch (159), harbor (46), bucket (12), bootbox (12) and cozy-lib-tests (87), the last with a new suite that calls the helper directly. postgres (209), kafka (98), kubernetes (346), mariadb (163), etcd (25), seaweedfs (39) and monitoring (31) pass unchanged.
helm template of redis with a 53-character release name renders the four hook objects as <release>-secrets-c, 63 characters, where the name was 69 before the cut. Renovate in local extract mode finds the clastix/kubectl pin in _hooks.tpl, 5 package files instead of 4.
hack/app-cleanup-hooks_test.bats now also runs the rendered harbor, bucket and bootbox hooks against its fake kubectl. It pins that the Secret goes after its Certificate, stays when the Certificate delete failed, and that a Secret which may remain makes the Job exit non-zero (22 tests). hack/chainsaw-leak-guard_test.bats covers the guard against a stub kubectl (47 tests). Both pass under Bats 1.14.0 and through hack/cozytest.sh under dash, and the guard tests also pass with the jq 1.7 and bash 5.2 of Ubuntu 24.04, which the E2E sandbox image is built on.
Every new rule was checked by breaking it in a copy of the tree. 17 mutations of the hooks and the helper, 12 of the rendered hook scripts and 13 of the guard, such as dropping the creation-time filter, the Certificate walk, the metadata cut, pipefail, the name check, the name cut to 63 characters, the cozy-lib.image call or the final non-zero exit of the bucket hook, each turn at least one named test red.
shellcheck reports nothing on the guard, the runner and the three rendered hook scripts.
The Makefile's Bats unit list, 176 files, run on main and on this branch side by side under Bats 1.14.0 on macOS, adds 26 new tests that all pass. Both trees fail the same 121 tests there, and no test that passes on main fails on the branch.
Not in this PR.
Secrets orphaned by deletions before this change stay. A hook runs only when a release is uninstalled.
mariadb, kubernetes and etcd keep their own Secret deletion, which already works.
The tenant wildcard Certificate of extra/ingress is not covered. It is issued only for the publishing tenant, and its Secret name is the _cluster.wildcard-secret-name an operator also sets for a wildcard Secret of their own, so deleting it on uninstall could remove a Secret the release never wrote.
The TenantGateway controller deletes the Certificates it owns but not the Secrets they wrote, and it has no access to Secrets at all. Covering it means granting the controller delete on Secrets, which needs a decision of its own.
The diff adds hook templates and tests to eight apps, a helper with its own tests to cozy-lib, the Secret check to the E2E leak guard, a file pattern to the Renovate config and lines to the agent docs. It moves or renames nothing under hack/, and changes no values, schema, defaults, package names, make targets or ApplicationDefinition, so nothing in the trigger map applies.
Release note
fix(cozy-lib): deleting a qdrant, redis, rabbitmq, nats, opensearch, harbor, bucket or bootbox app now also deletes the TLS Secrets cert-manager wrote for it, so their private keys no longer stay in the tenant namespace, and the E2E run fails a suite that leaves such a Secret behind.
Summary by CodeRabbit
Bug Fixes
TLS Secrets created for certificates are now cleaned up when supported releases are deleted, including certificates created indirectly by ingress integrations. Certificates are removed before their Secrets, and cleanup reports failures rather than silently leaving key material behind.
Cleanup preserves shared wildcard TLS Secrets instead of deleting credentials still used elsewhere.
New Features
End-to-end leak checks now detect cert-manager Secrets that remain after a test suite, alongside leaked pods. Reports identify the affected resource type and account for allowlisted and inconclusive results.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
A shared Helm hook now deletes listed cert-manager Certificates before their Secrets. Several charts configure post-delete cleanup for TLS Secrets. Bucket and Harbor cleanup handles shared wildcard TLS. The Chainsaw leak guard tracks eligible cert-manager Secrets alongside pods and reports them separately.
The shared template validates the listed names, creates scoped cleanup resources, and runs a Job that deletes Certificates before Secrets. Tests cover RBAC, deletion order, and invalid inputs. The Helm convention documents which Certificate Secrets to list. Renovate now scans the shared hook template for kubectl image digests.
Cleanup for NATS, OpenSearch, Qdrant, RabbitMQ, and Redis packages/apps/nats/..., packages/apps/opensearch/..., packages/apps/qdrant/..., packages/apps/rabbitmq/..., packages/apps/redis/...
The charts pass release-specific Secret names to the shared hook. Their tests check Role scope, Job settings and failures, rendering conditions, and covered Certificates.
Ingress and application TLS cleanup packages/extra/bootbox/..., packages/apps/bucket/..., packages/apps/harbor/..., hack/app-cleanup-hooks_test.bats
Bootbox configures cleanup for its Ingress-owned Certificate and Secret. Bucket and Harbor delete their TLS Secrets only after Certificate deletion succeeds. They omit Certificate and Secret cleanup when the TLS Secret matches the configured wildcard Secret. Tests cover ordering, failures, wildcard handling, and scoped permissions.
The leak guard checks annotated TLS Secrets created during a suite and traces their owner chain. Secret and pod leaks share a cleanup budget and wait, with separate report markers. Tests cover attribution, timeout behavior, errors, allowlisting, and runner reporting.

europrinter (@yankawai) NOT LGTM, one blocker: the cleanup Job name can go past 63 characters for app names the API accepts, and then uninstall fails.
The fix itself is worth taking. Selecting by resourceNames instead of the shared controller.cert-manager.io/fao label is the right call, every Secret name matches the secretName in the app's certmanager.yaml, and the hook runs only on uninstall. It does not overlap with the kubernetes cleanup either, since that app is not wired to the new helper. On a trial merge with current main, helm unittest passes for cozy-lib-tests and all eight charts (bootbox with helm-unittest 1.1.2, the version CI pins), both Bats files pass, and dropping the resourceNames list or the name check from the helper turns cozy-lib-tests red.
The blocker is the Job name, <release>-secrets-cleanup. The apps API caps the release name at 53 characters, prefix included (maxHelmReleaseName in pkg/registry/apps/application/rest.go), so this name can reach 69. Kubernetes copies a Job's name into the job-name labels of its pod template, and a label value is limited to 63 characters, so the apiserver rejects the Job. A redis app named with 42 to 47 characters renders exactly that:
On main these redis, rabbitmq, nats and opensearch apps uninstall fine, because they have no hook or a short one (-cleanup). With this PR the post-delete hook cannot be created, Helm reports the uninstall as failed, and the Secrets stay anyway. qdrant already has this problem through -qdrant-cleanup, so it is not new there.
Since the release name is at most 53, printf "%s-secrets-cleanup" $root.Release.Name | trunc 63 | trimSuffix "-" keeps the whole release name and stays unique. Please add a cozy-lib-tests case with a 53-character release name that checks the Job name length.
Not blocking, but worth doing in the same push: the helper pulls docker.io/clastix/kubectl:v1.32@sha256:... directly. The harbor, mariadb, opensearch and kafka hooks pass the same ref through cozy-lib.image. Also, the Renovate manager that refreshes this digest only matches packages/.+/templates/hooks/.+\.yaml, so the pin in _hooks.tpl will silently age while the other hooks get bumped.
The reason will be displayed to describe this comment to others. Learn more.
With a 53-character release name this is 69 characters, and the Job is rejected because its name goes into the 63-character job-name label. | trunc 63 | trimSuffix "-" here is enough, since the release name itself is at most 53.
…deleted
cert-manager runs without --enable-certificate-owner-ref, so the Secret a
Certificate writes has no owner and outlives the release. qdrant, redis,
rabbitmq, nats and opensearch mint their own CA and leaf certificate and had
no cleanup for them, so deleting one of these apps left Secrets holding
tls.key in the tenant namespace, and a later app of the same name could pick
up a key it did not create.
The cleanup is one post-delete hook in cozy-lib that an app feeds with the
Secret names its Certificates can write, so every app gets the same
least-privilege delete by name and the same non-zero exit on a failed delete
instead of a hand-written copy. Turning the cert-manager flag on would change
the same behaviour for every Certificate the platform itself issues,
including the CA Certificates its own components trust.

harbor, bucket and bootbox get their Ingress certificate from
cert-manager's ingress-shim. The harbor and bucket hooks deleted that
Certificate on uninstall, bootbox had no hook at all, and none of them
deleted the Secret the Certificate wrote. With
--enable-certificate-owner-ref off, that Secret and the private key of
the app host stayed in the tenant namespace.
harbor and bucket now delete the Secret by name right after the
Certificate, and only when the Certificate delete succeeded, because
cert-manager issues the Secret of a live Certificate again. bootbox gets
the cozy-lib hook, which now takes an optional list of such Certificates
and deletes them before the Secrets.

cert-manager runs without --enable-certificate-owner-ref, so the Secret a
Certificate writes outlives the Certificate and the release, and a later
release of the same name finds and reuses the private key in it. The leak
guard only looked at pods, so a suite that deleted its app and left those
Secrets behind still passed.
A Secret is charged to a suite when it carries cert-manager's
certificate-name annotation, was created after the suite started, and the
root of its chain was too, where a Secret with no owners of its own is
walked as if its Certificate owned it. A platform Secret re-issued
mid-suite traces back to a Certificate the install created, while one
whose Certificate is gone is charged. Charged Secrets get the same budget
as pods and are reported under their own LEAKED-SECRETS marker, so the pod
markers read as before.
The list is read with a kubernetes.io/tls field selector and cut to
metadata inside the pipe from kubectl, so the keys it carries never reach
the shell.

The hook writes the Secret and Certificate names into its shell script

a caller from passing one that the shell would run. Anything that is not
a Kubernetes resource name now fails rendering.

The hook only warned when it could not delete the UI TLS Secret, so it
still exited 0 and hook-succeeded removed the Job and its log while the

and exits non-zero whenever that Secret may remain. Leftover ACME objects
keep the warning they always had.

Aleksei Sviridkin (@lexfrei) thanks, both in. rebased onto current main (aed7fa8), the only conflict was one line in hack/e2e-chainsaw/README.md and both sides are kept. two commits on top, the other five are unchanged apart from that line.
job name, 57d2e75. the helper builds the name as printf "%s-secrets-cleanup" $root.Release.Name | trunc 63 | trimSuffix "-" and uses it for the ServiceAccount, Role, RoleBinding and Job. cozy-lib-tests gets three cases with a 53 character release name. they check that the Job is <release>-secrets-c and at most 63 characters, that all four objects carry that name and that the RoleBinding points at the cut Role and ServiceAccount. without the trunc all three go red. helm template of redis with a 53 character release now renders a 63 character Job name, 69 before.
image, cb1891c. the helper passes clastix/kubectl:v1.32@sha256:... through cozy-lib.image like the harbor, mariadb, opensearch and kafka hooks, and the clastix/kubectl renovate manager now also matches packages/library/cozy-lib/templates/_hooks.tpl. renovate --platform=local --dry-run=extract (44.165.0) finds 5 package files with the pin, _hooks.tpl among them, and 4 on the commit before. the five app suites expect the registry-relative ref now and cozy-lib-tests checks the images-registry prefix.
helm unittest 1.1.2 passes for cozy-lib-tests 87/87, qdrant 112/112, redis 74/74, rabbitmq 109/109, nats 81/81, opensearch 159/159, harbor 46/46, bucket 12/12 and bootbox 12/12. both bats files pass, 22 and 47 tests, and the rest of the bats lane fails only where bare main fails in the same environment.

europrinter (@yankawai) NOT LGTM. The cleanup can delete a configured shared wildcard Secret. For example, publishing.certificates.wildcardSecretName: bootbox-tls is supported, but packages/extra/bootbox/templates/hooks/cleanup-secrets.yaml:4-7 always passes that name to the cleanup helper. In wildcard mode the app creates no per-app TLS Secret, yet uninstall removes the operator-provided one.
Evidence: I checked full chart renders and ran the rendered hooks against a fake store. The shared Secret is removed on this branch; the same configuration on main and a wildcard name outside the cleanup targets preserve it.
Please preserve the configured shared wildcard Secret and delete only app-owned targets, including in the separate Harbor and bucket hooks. Keep cleanup for keys left by earlier TLS-enabled revisions, even when TLS is off now.
The previous Job-name blocker and the image/Renovate points are fixed. Functional CI has not run on this head.
A shared wildcard Secret can use the same name as an old per-app key. Uninstall must preserve that Secret while still reclaiming keys from earlier TLS-enabled revisions.

Prevent in-flight issuance from recreating the Secret.
If the Certificate remains during deletion, an in-flight issuance can recreate the Secret after the hook deletes it. The hook then reports success while the private key remains. Coordinate cleanup with in-flight cert-manager writes; waiting for Certificate deletion alone does not stop a reconciliation already in progress.

Verify Secret provenance before deleting it.
In wildcard mode, the hook deletes <release>-ingress-tls even if another application owns it. For example, a Kubernetes Proxmox controller can use that name for its credentials Secret. Deleting Harbor then removes those credentials. Identify legacy Harbor Secrets before deletion rather than relying on the name alone.

Update the cleanup hook’s deletion of the release-named ingress TLS Secret to
verify that it is a legacy Harbor Secret using reliable ownership metadata or
labels before deleting it. Do not rely on the Secret name alone; leave it
untouched when Harbor provenance cannot be confirmed.

Certificate filtering does not follow the target Secret.
If an operator-created bootbox-tls Certificate targets a differently named wildcard Secret, uninstalling bootbox can delete the Certificate and stop renewal of the shared Secret.
The reverse also matters: a Certificate named like the wildcard Secret can target an app Secret. The filter retains that Certificate while deleting the app Secret, which the Certificate can then reissue. The Certificate’s spec.secretName, not its metadata name, distinguishes these cases.

Update the `$certificates` filtering around `$wildcardSecret` to use each
Certificate’s `spec.secretName`, not its metadata name: preserve Certificates
targeting the wildcard Secret and exclude Certificates targeting app Secrets,
even when their metadata names match the wildcard Secret.

If the only listed Secret matches the wildcard name, the helper omits the hook even when a differently named Certificate remains. That Certificate can remain after uninstall. Render Certificate cleanup independently, without granting unrestricted Secret deletion.

Update the cleanup hook condition around $secrets so Certificate cleanup is
rendered when a remaining Certificate needs cleanup, even if the only listed
Secret matches the wildcard name. Keep Secret deletion restricted to its

## What this PR does
The apps API admits release names of up to 53 characters, the release
prefix included (less for Kafka and Kubernetes, which cap their own
names). Kubernetes copies a Job name into the `job-name` label of its
pods, and a label value takes at most 63 characters, so the apiserver
refuses a Job with a longer name. A CronJob name is refused over 52
characters, because the controller names each Job it starts
`<cronjob>-<timestamp>`. I rendered every Job and CronJob in
`packages/apps` and `packages/extra` with the longest release name each
application admits, and eight of them go over.
| Application | Object | Name | Longest on main | After |
| --- | --- | --- | --- | --- |
| bucket | post-delete Job | `<release>-cleanup-acme` | 66 | 63 |
| qdrant | post-delete Job | `<release>-qdrant-cleanup` | 68 | 63 |
| kafka | pre-install and pre-upgrade Job | `<release>-kafka-migration`
| 66 (release capped at 50) | 63 |
| vm-disk | resize Job, rendered when the disk grows |
`<release>-volume-resize-hook` | 72 | 63 |
| vm-instance | update Job and the `app` label of its pod |
`<release>-update-hook` | 65 | 63 |
| mariadb | backup CronJob | `<release>-backup` | 60 | 52 |
| clickhouse | legacy backup CronJob | `<release>-backup` | 60 | 52 |
| tenant | pre-delete Job in `cozy-system` | `<tenant
namespace>-cleanup` | 71 (nested namespace of 63) | 63 |
Counted in characters of the application name, a Kafka of 42 to 44
cannot be installed today, a VMDisk of 37 or more cannot grow, and a
VMInstance of 40 or 41 cannot take an instance type, profile or external
change. Deleting a Bucket of 44 or more or a Qdrant of 42 or more fails
in the post-delete hook. With the backup CronJob enabled, a MariaDB of
38 or more and a ClickHouse of 35 or more fail the whole release. A
nested tenant whose namespace is longer than 55 characters cannot be
deleted.
The Jobs of bucket, qdrant, kafka, vm-disk and vm-instance are now named
`printf "%s-<suffix>" .Release.Name | trunc 63 | trimSuffix "-"`, and
vm-instance uses the same value for the pod label. A release name is
never longer than 53, so only the fixed suffix is cut, and a brute-force
check over every pair of release name lengths found no two release names
that render the same Job name.
A plain cut to 52 would reach into the release name of a CronJob, and
two 53-character names that differ in the last character would share
one. So a CronJob name that does not fit becomes the release name cut to
38 characters, the first six hex characters of its sha256 and `-backup`,
the shape #4133 gave the ClickHouse Keeper name. The tenant cleanup Job
takes the same form with the namespace cut to 48, because it runs in
`cozy-system` next to the cleanup Job of every other tenant. There a
plain cut gives a parent and a child named `clea` the same name, and the
child's `before-hook-creation` would delete the parent's Job while it
runs.
Names that fit render exactly as before. The hook documents rendered
from main and from this branch with the short release names the tests
use are identical in all eight charts. A name that did not fit never
produced an object, so nothing is renamed on upgrade. The
ServiceAccounts, Roles and RoleBindings of these hooks keep their names,
since they have no such limit, so the ones a pre-install hook left
behind are replaced rather than orphaned. Helm runs the delete hooks
stored with a release, so an existing Bucket, Qdrant or tenant picks up
the fix with its next upgrade.
Every other Job and CronJob fits at the longest name. The cleanup Jobs
of clickhouse, harbor, mariadb and opensearch and the Kafka pre-delete
Job reach 61, the Postgres init Job 62, and the Kubernetes and
KubernetesNodes Jobs either stay under 63 or already cut their names.
The etcd and monitoring modules require their chart name as the release
name, and the gateway and seaweedfs cleanup Jobs reach 61.
Each of the eight charts gets a new helm-unittest suite. It pins a short
name, a name that lands exactly on the limit and the longest admitted
name, a cut that would end in a dash wherever one can happen, and for
the hooks the unchanged ServiceAccount and RBAC names. The CronJob
suites also pin two 53-character names that differ in the last
character, and the tenant suite pins the parent and child pair. Against
the templates on main, 18 of the 41 new cases fail, every one with a
name over the limit. With the hash forms replaced by a plain cut, the
tenant parent and child both render
`tenant-abcdefghijklmnopqrstuvwxyz-0123456789abcdefghijklmn-clea` and
the two MariaDB names both render
`mariadb-abcdefghijklmnopqrstuvwxyz0123456789abcdefgh`.
`hack/helm-unit-tests.sh` passes over all 106 packages with tests. The
Bats files that exercise these hooks and charts
(`app-cleanup-hooks_test`, `kafka-migration-hook`,
`kafka-pre-delete-hook`, `tenant-pre-delete-hook`,
`check-hook-request-timeout`, `pod-label-census_test`,
`mariadb-first-boot-waits`, `check-render-matrix`) give 96 ok on main
and on this branch. `make generate` with cozyvalues-gen v1.7.0 in the
eight packages changes nothing. A local kube-apiserver v1.35.0 refuses
the longest name each chart renders on main, with `must be no more than
63 bytes` on the job-name label or `must be no more than 52 characters`
on the CronJob, and creates the name from this branch. For vm-disk and
vm-instance, whose hooks render only after a live lookup, that check
used a Job with the same name and labels.
This is related to #4875 but does not depend on it. #4875 adds a
cozy-lib cleanup Job and cuts its name to 63 the same way, while this PR
covers the Jobs already on main. Neither needs the other, and the two
merge cleanly.

### Release note
```release-note
fix(apps): Job and CronJob names now fit the Kubernetes limits for the longest application names. A Kafka with a name of 42 to 44 characters can now be installed, long VMDisk and VMInstance names no longer fail a resize or an instance type change, long Bucket and Qdrant names and long nested tenant namespaces no longer fail deletion, and long MariaDB and ClickHouse names no longer fail the release with the backup CronJob enabled.

## Summary by CodeRabbit
* **Bug Fixes**
* Cleanup, migration, resize, and update Jobs now use names that fit
Kubernetes naming limits, including for long release or tenant names.
* ClickHouse and MariaDB backup CronJobs now use names within
Kubernetes’ length limit. Longer names are shortened with a hash suffix
to help distinguish them.
* Short names and names at the supported limit retain their existing
naming format.

What this PR does
Addresses #4704. Deleting an app left the Secrets cert-manager wrote for it in the tenant namespace, private keys included, because cert-manager runs with
enableCertificateOwnerRef: falseand nothing else deletes them. This PR deletes them for every app where that happens and makes the E2E run fail a suite that still leaves one behind. It also takes in #4876, closed so that the check lands together with the fix it checks.Seven commits.
fix(cozy-lib)addscozy-lib.hooks.deleteSecrets, a post-delete hook (ServiceAccount, Role, RoleBinding, Job) that an app feeds with the Secret names its Certificates can write, and wires qdrant, redis, rabbitmq, nats and opensearch to it. Of the other apps that mint their own CA and leaf, mariadb, kubernetes (Talos PKI) and etcd already delete those Secrets in their own hooks.fix(apps)covers the Secrets of Ingress certificates. harbor, bucket and bootbox get theirs from cert-manager's ingress-shim. The harbor and bucket hooks deleted that Certificate but not its Secret, and bootbox had no hook at all. harbor and bucket now delete the Secret right after the Certificate, and bootbox uses the cozy-lib hook, which takes an optionalcertificateslist for this case. Tenant monitoring and seaweedfs already delete theirs.test(e2e)extends the E2E leak guard of test(e2e): fail the suite whose pods outlive its cleanup #4492 from pods to these Secrets.fix(cozy-lib)makes the hook accept only Kubernetes resource names, because it writes them into its shell script inside double quotes.fix(bucket)makes the bucket hook fail whenever its UI TLS Secret may remain, instead of only warning.fix(cozy-lib)cuts the names of the hook objects to 63 characters, because the apps API admits release names of up to 53 and a Job name goes into the 63-characterjob-namelabel of its pods.fix(cozy-lib)builds the hook image withcozy-lib.image, so the cluster images registry applies, and adds_hooks.tplto the Renovate manager that refreshes the clastix/kubectl digest.How the cleanup works.
resourceNames. cert-manager stamps its Secrets only with the cluster-widecontroller.cert-manager.io/faolabel, so a label sweep would reach sibling apps in the namespace.resourceNamesgrants delete on every Secret in the namespace. So does any entry that is not a Kubernetes resource name, because the names go into the Job's shell script inside double quotes, where$and a backquote are still expanded.hook-succeeded. A Secret that is already gone is not a failure. The bucket hook still only warns about leftover ACME objects, as it did before, but now fails whenever its Secret may remain.How the guard works.
cert-manager.io/certificate-nameannotation, was created at or after the suite started, and the root of its chain was too. A Secret with no owners of its own is walked as if the Certificate the annotation names owned it, then up that Certificate's ownerReferences like a pod. A platform Secret re-issued mid-suite traces back to a Certificate the install created and is not charged, and one whose Certificate is gone is. A Secret an operator patched an owner onto, like the PerconaServerMongoDB ones, is walked through that owner.kubectl wait --for=deleteas pods, and are reported under their ownLEAKED-SECRETSmarker andleaked-secretsannotation with the Certificate and root of each. The pod markers are unchanged. The allowlist stays per suite and covers both kinds.kubectl get secrets --field-selector type=kubernetes.io/tls, cut to metadata inside the pipe from kubectl, so it does not carry every stored Helm release revision along and the keys never reach a shell variable.Why not the global flag.
enableCertificateOwnerRef: truewould change the same behaviour for every Certificate the platform issues, the CA Certificates of its own components among them, and a Certificate removed or renamed in a platform chart would take its key with it. A per-Certificate owner reference is not available either, asspec.secretTemplatein cert-manager v1.20 carries labels and annotations only.E2E criterion, registered before the run. Every suite prints
leak-guard: suite=<dir> clear after, or aLEAKED-SECRETSline carryingallowlisted=,checked-once=orinconclusive=, and no line matchesLEAKED-SECRETS suite=.* budget=. Without the two fixes, reading the charts and suites on main, the guard fails qdrant, redis and opensearch, redis forredis-secureand forredis-flip, whose refused TLS upgrade still creates Certificates. That is the leak the first two commits remove. harbor, bucket and bootbox cannot show theirs in E2E, because the sandbox never completes an ACME order.Testing.
helm templateof redis with a 53-character release name renders the four hook objects as<release>-secrets-c, 63 characters, where the name was 69 before the cut. Renovate in local extract mode finds the clastix/kubectl pin in_hooks.tpl, 5 package files instead of 4.hack/app-cleanup-hooks_test.batsnow also runs the rendered harbor, bucket and bootbox hooks against its fakekubectl. It pins that the Secret goes after its Certificate, stays when the Certificate delete failed, and that a Secret which may remain makes the Job exit non-zero (22 tests).hack/chainsaw-leak-guard_test.batscovers the guard against a stubkubectl(47 tests). Both pass under Bats 1.14.0 and throughhack/cozytest.shunder dash, and the guard tests also pass with the jq 1.7 and bash 5.2 of Ubuntu 24.04, which the E2E sandbox image is built on.pipefail, the name check, the name cut to 63 characters, thecozy-lib.imagecall or the final non-zero exit of the bucket hook, each turn at least one named test red.Not in this PR.

Downstream repositories
The diff adds hook templates and tests to eight apps, a helper with its own tests to cozy-lib, the Secret check to the E2E leak guard, a file pattern to the Renovate config and lines to the agent docs. It moves or renames nothing under
hack/, and changes no values, schema, defaults, package names, make targets orApplicationDefinition, so nothing in the trigger map applies.Release note
