feat(monitoring-agents): export PVC labels from kube-state-metrics - #5215
Adds persistentvolumeclaims=[*] to the kube-state-metrics --metric-labels-allowlist, next to the existing pods=[*] and deployments=[*]. kube-state-metrics then publishes kube_persistentvolumeclaim_labels, one series per PVC, with the PVC's labels as label_*.
Why: the per-application metrics scope in the design proposal Tenant resource-consumption metrics (Phase 0) finds an application's volumes through the apps.cozystack.io/application.* lineage labels on its PVCs. Without this series, volume usage (kubelet_volume_stats_*, which carries persistentvolumeclaim but not pod) cannot be attributed to an application.
[*] rather than an explicit key list: kube-state-metrics has no prefix matching, so the three lineage keys would have to be enumerated, and the series count is the same either way (one per PVC). [*] stays consistent with the existing pods and deployments entries and does not silently miss a lineage key added later. PVCs are far fewer than pods, which already export all labels.
How it was tested
helm-unittest for monitoring-agents: a new suite asserts the exact flag in the rendered kube-state-metrics Deployment.
Verified on a test cluster: kube_persistentvolumeclaim_labels is present and carries label_apps_cozystack_io_application_name.
Not verified: the memory impact on kube-state-metrics.
Known limitation
PVCs created from a StatefulSet's volumeClaimTemplates usually have no owner reference and no Flux label, so the lineage webhook gives them no lineage labels and this series cannot attribute them to an application. Fixing that belongs to the lineage webhook.
Screenshots
No UI changes.
Downstream repositories
No downstream repository is affected by this change
Downstream: no trigger matched. Candidate: none affected, because the diff touches only packages/system/monitoring-agents/values.yaml and a test in that system package; it adds a series but renames no telemetry metric, platform value, app field or CRD.
Release note
feat(monitoring-agents): kube-state-metrics now exports PVC labels as `kube_persistentvolumeclaim_labels`, one series per PVC, so volume usage can be attributed to the application that owns it.
Summary by CodeRabbit
New Features
Kubernetes monitoring metrics now include labels from pods, deployments, and persistent volume claims. This expands the resource metadata available alongside metrics, including lineage labels used by the tenant metrics API. Metrics for these resource labels are emitted only for resources covered by the configured label allowlist.
The tenant metrics API scopes a query to one application by looking up
its pods and PVCs through their apps.cozystack.io/application.* lineage
labels. kube-state-metrics emits kube_persistentvolumeclaim_labels only
for resources on --metric-labels-allowlist, so without PVCs there the
PVC half of that lookup always comes back empty and volume series of
an application fall out of its scope.
All labels are allowed, as for pods and deployments: kube-state-metrics
emits one series per PVC whatever keys are listed, and PVCs are far
fewer than pods, which already export every label.

Signed-off-by: ZverGuy <[email protected]>
The kube-state-metrics label allowlist now includes labels from persistent volume claims, in addition to pod and deployment labels. A Helm test checks that the deployment arguments contain the expected allowlist.

Summary
Configure and test label allowlist packages/system/monitoring-agents/values.yaml, packages/system/monitoring-agents/tests/kube_state_metrics_labels_test.yaml
The values add all PVC labels to the kube-state-metrics allowlist and update its comments. The Helm test asserts the exact allowlist argument for pods, deployments, and PVCs.
cozystack/cozystack#5124: Extends lineage resolution for CAPK VMs and reports lineage labels on data-volume PVCs. This PR exposes PVC labels through kube-state-metrics for application-scoped metrics.
Merge Risk: Low · up to 7de70
The default configuration supports PVC label export. Operators following the nodes-label override example can lose those labels; update the example to preserve the full allowlist. This is a bounded configuration risk.

Explanation
The title "feat(monitoring-agents): export PVC labels from kube-state-metrics" matches the main change. The PR adds persistentvolumeclaims=[*] to kube-state-metrics' --metric-labels-allowlist, so kube_persistentvolumeclaim_labels carries PVC labels. The raw summary also confirms the allowlist now includes PVCs alongside pods and deployments, and a new Helm test checks the flag. The title names the component and the specific change. It does not mention the test or the comment updates, which is acceptable because it need not cover every detail.

## 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.

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(seaweedfs): bucket users granted together could get S3 keys that never work (403 InvalidAccessKeyId). COSI driver is bumped to v0.4.0, which writes each grant to per-identity IAM file.
```
)
## What this PR does
Depends on #5219. This PR is stacked on that branch; the description
covers only what it adds on top.
Adds the per-application roots to the observability proxy, as described
in the design proposals [Tenant application
logs](cozystack/community#95) and [Tenant
resource-consumption
metrics](cozystack/community#94):
```text
/apis/apps.cozystack.io/v1alpha1/namespaces/<ns>/<plural>/<name>/log/select/logsql/<endpoint>
/apis/apps.cozystack.io/v1alpha1/namespaces/<ns>/<plural>/<name>/metrics/api/v1/<endpoint>
```
This lets the console show the logs and resource consumption of one
application rather than of the whole namespace.
What is added:
- Plural-to-Kind mapping from an informer over `ApplicationDefinitions`.
The Kind is looked up only after the `SubjectAccessReview` (`get
<plural>/log` or `get <plural>/metrics`), so an unauthenticated caller
cannot probe which plurals exist. An unknown plural answers `404`; an
unsynced cache or a plural declared by two kinds answers `503`.
- Logs: a second `extra_stream_filters` value with the application Kind
and name, on top of the unchanged namespace filter. VictoriaLogs ANDs
the two, on every endpoint including `tail`.
- Metrics: the forced `extra_filters[]` becomes an OR of three branches,
each still bound to the namespace:
1. series carrying the application identity labels;
2. series of the application's pods, found through `kube_pod_labels`;
3. series of the application's PVCs, found through
`kube_persistentvolumeclaim_labels`.
- The pod and PVC lookups cap the number of names
(`--metrics-app-max-pods`, `--metrics-app-max-pvcs`); over the cap
answers `422`. A failed pod or PVC lookup fails the request (`502`, or
`504` on the deadline) rather than answer without the application's
series, and so does a lookup that vmselect marks `isPartial`, since a
storage node that did not answer leaves names out (a partial list
already over the cap still answers `422`); vmselect's series-limit
refusal of a lookup is passed through as `422`. A query that reads
further back than `--metrics-app-lookback` (default 720h, chart value
`observabilityProxy.metrics.appLookback`), or by an unknown amount, and
a query whose samples lie at a time the lookup cannot cover answer `422`
on the application root; this includes every query with an `@` modifier,
`WITH` with a negative offset, and offsets that are not plain durations.
The namespace root still serves them. `rollup_candlestick`, a backslash
or a `#` comment outside a string, an offset directly followed by a
minus (compound durations such as `-1h-30m` or `1h-2h`), and a subquery
step that is not a plain duration are refused as well. The lookup
reaches past the evaluation time by any negative offset and by two steps
per subquery level.
- Application routes require read access to the namespace root as well
as the application subresource; a grant narrowed with `resourceNames`
alone answers `403`.
- The proxy's ClusterRole gains `list`/`watch` on
`cozystack.io/applicationdefinitions`. No tenant RBAC change is needed:
the `view` role already allows `get` on every `apps.cozystack.io`
resource and subresource.
- `/readyz` now also waits for the `ApplicationDefinitions` cache, so a
missing CRD or RBAC rule keeps the whole proxy unready, namespace roots
included.
#### Data comes from the identity labels
The application roots find data only through identity labels added by
three PRs that are now in main:
- #5215 `feat(monitoring-agents)`: export PVC labels from
kube-state-metrics (PVC branch).
- #5216 `feat(monitoring)`: stamp application identity on scraped series
(identity branch).
- #5217 `feat(monitoring-agents)`: keep application identity in
container log streams (logs root).
Merge after #5219.
The pod branch does not depend on them, because `kube_pod_labels`
already exports all pod labels. Logs and series written before those
changes rolled out carry no identity and are reachable only through the
namespace root.
#### Security condition: a convenience filter, not an isolation boundary
The application roots narrow the namespace roots; they do not isolate
applications from each other. Each application route therefore requires
two grants: the application subresource (`get <plural>/log` or `get
<plural>/metrics`) and read access to the namespace root (`list
cozystack.io/logs` or `cozystack.io/metrics` in the namespace). A grant
narrowed with `resourceNames` alone is refused. Every tenant role that
can read applications already has both. The application scope cannot
isolate yet because:
1. The lineage webhook keeps `apps.cozystack.io/application.*` labels
that a user sets on a pod or PVC that has no application owner, so such
an object can claim another application's identity.
2. The webhook's `objectSelector` skips any object created with
`internal.cozystack.io/managed-by-cozystack`, pods included, so forged
labels on such an object are never examined.
3. The pod and PVC branches match by name over the lookup window, so an
object that reuses the name of another application's recently deleted
pod or PVC pulls that object's older series into scope.
The proposed fix (a separate change to the lineage webhook) is to strip
the identity labels when no owner resolves, and to stop skipping CREATE
requests for objects carrying the managed-by label.
#### Other known gaps
- PVCs created from a StatefulSet's `volumeClaimTemplates` usually get
no lineage labels, so their volume series are not in the application
scope.
- ingress-nginx series intentionally carry no application identity, so
they are reachable only through the namespace root.
- A request for an application that does not exist answers `200` with an
empty result rather than `404`: the proxy checks authorization, not
existence. Nothing leaks; whether a `404` is wanted is open for review.
#### How it was tested
- `go test -race` and `go vet` for the proxy packages, including a
narrowed-grant test (access to application `a` only): every application
path for `b` answers `403` and no request reaches the store. Name
escaping in the pod and PVC branches is covered for regex metacharacters
and quotes.
- helm-unittest for `observability-proxy` (new RBAC rule).
- Verified on a test cluster, with the three identity PRs above applied:
the application logs root of a Redis instance returned only that
instance's lines and none from a neighbouring pod in the same namespace;
its application metrics root returned only the Redis pods' series.

Downstream: no trigger matched. Candidate: none affected, because the
diff on top of #5219 is confined to the proxy's Go code and its own
chart RBAC; it reads `ApplicationDefinitions` but does not change their
semantics or the CRD. The security condition above may deserve a note in
the design proposals in `cozystack/community`, which is not a
trigger-map item.
### Release note
```release-note
feat(observability-proxy): add per-application logs and metrics roots under `/apis/apps.cozystack.io/v1alpha1/namespaces/<ns>/<plural>/<name>/{log,metrics}/`, scoped by application identity labels. Data appears for logs and series collected after the application identity changes to Fluent Bit, VMAgent and kube-state-metrics are rolled out.

## Summary by CodeRabbit
* **New Features**
* Added a tenant-aware observability proxy for logs and metrics, with
namespace and application scoping, access checks, and per-user request
limits.
* Enabled the proxy in the system package bundle and routed console log
and metrics requests through it.
* Added live log streaming and health, readiness, and metrics endpoints.
* **Bug Fixes**
* Invalid or excessive query parameters are rejected; requests with
uncertain application-metric scope are refused rather than returning
incomplete results.
* **Tests**
* Added end-to-end and integration coverage for tenant isolation,
console routing, access controls, and log streaming.

What this PR does
Adds
persistentvolumeclaims=[*]to the kube-state-metrics--metric-labels-allowlist, next to the existingpods=[*]anddeployments=[*]. kube-state-metrics then publisheskube_persistentvolumeclaim_labels, one series per PVC, with the PVC's labels aslabel_*.Why: the per-application metrics scope in the design proposal Tenant resource-consumption metrics (Phase 0) finds an application's volumes through the
apps.cozystack.io/application.*lineage labels on its PVCs. Without this series, volume usage (kubelet_volume_stats_*, which carriespersistentvolumeclaimbut notpod) cannot be attributed to an application.[*]rather than an explicit key list: kube-state-metrics has no prefix matching, so the three lineage keys would have to be enumerated, and the series count is the same either way (one per PVC).[*]stays consistent with the existing pods and deployments entries and does not silently miss a lineage key added later. PVCs are far fewer than pods, which already export all labels.How it was tested
monitoring-agents: a new suite asserts the exact flag in the rendered kube-state-metrics Deployment.kube_persistentvolumeclaim_labelsis present and carrieslabel_apps_cozystack_io_application_name.Known limitation
PVCs created from a StatefulSet's
volumeClaimTemplatesusually have no owner reference and no Flux label, so the lineage webhook gives them no lineage labels and this series cannot attribute them to an application. Fixing that belongs to the lineage webhook.Screenshots
No UI changes.
Downstream repositories
Downstream: no trigger matched. Candidate: none affected, because the diff touches only
packages/system/monitoring-agents/values.yamland a test in that system package; it adds a series but renames no telemetry metric, platform value, app field or CRD.Release note
