feat(monitoring-agents): keep application identity in container log streams by kitsunoff · Pull Request #5217 · cozystack/cozystack

Maxim Kitsunoff (kitsunoff) · 2026-11-04T13:13:17Z

What this PR does

Makes Fluent Bit keep the pod lineage labels apps.cozystack.io/application.{group,kind,name} on container log lines, as the stream fields apps_cozystack_io_application_{group,kind,name}, for both the default container-log output and the per-tenant routed output.

Why: the per-application logs scope in the design proposal Tenant application logs (section 6) filters by these stream fields. Today the kubernetes filter fetches pod labels, but they are dropped together with the rest of the kubernetes_* keys before output.

What changes in the pipeline:

A second nest lift of the pod labels, then a rename of the three lineage keys to their final names before the existing Remove_wildcard kubernetes_ runs. All other labels are still removed. Every lifted key is prefixed, so no other label can collide into the identity names.
The three keys are added to _stream_fields of both container-log outputs. Events and audit pipelines are unchanged.
A parsed JSON log line is kept under log_processed (already on main), so a line's content cannot create the identity keys.
Guest Kubernetes clusters are not affected: their monitoring-agents release replaces the filters and outputs wholesale. A regression test in packages/apps/kubernetes pins that guest streams carry no identity fields.

Effect on existing streams: VictoriaLogs treats a missing stream field like an empty one, and the rename writes nothing when the label is absent. Pods without lineage labels keep exactly the same stream. Pods with lineage labels get a new stream once after the rollout; their earlier lines stay reachable by namespace.

How it was tested

helm-unittest for monitoring-agents (lift order, rename before Remove_wildcard, stream fields on both outputs, events and audit untouched) and for kubernetes (guest streams unchanged). The events/audit guard was mutation-checked.
Verified on a test cluster: real pod log lines arrive, Redis pods' lines carry the three apps_cozystack_io_application_* stream fields, and Fluent Bit logs show no errors.

Known limitation

Guest clusters write to the parent log store without authentication, so a guest administrator can forge these stream fields as well as the namespace field, within the store their tenant shares. This is the write-path trust risk already documented in the proposal.

Screenshots

No UI changes.

Downstream repositories

Downstream: no trigger matched. Candidate: none affected, because the diff changes packages/system/monitoring-agents/values.yaml (a system package with no schema) and adds tests; the file under packages/apps/kubernetes is a test only, so the app's values.yaml and values.schema.json are unchanged.

Release note

feat(monitoring-agents): container log lines of pods that belong to a Cozystack application now carry `apps_cozystack_io_application_{group,kind,name}` stream fields in VictoriaLogs. Streams of pods without application labels are unchanged; streams of application pods start a new stream once after the upgrade.

Summary by CodeRabbit

New Features
- Container-log streams now include application group, kind, and name metadata for root and tenant stores.
- Guest monitoring streams include pod name, container name, and namespace fields.
Bug Fixes
- Application metadata is added to container-log streams without changing the existing stream fields for event and audit outputs.

A reader that scopes logs to one application needs the owning application on every line, and the lineage webhook already puts it on the pod as apps.cozystack.io/application.{group,kind,name}. Fluent Bit fetched those labels and then dropped them with the rest of the kubernetes map, so the store could only be scoped by namespace. Keep the three labels as apps_cozystack_io_application_{group,kind,name}, the names the metrics side uses, and make them stream fields on every container-log output so the scope is an indexed stream filter. A pod without the labels produces no such fields, and VictoriaLogs builds the stream from the fields present, so existing streams keep their identity; a labelled pod starts a new stream once.

Guest pods are tenant-controlled, so their lineage labels are not a trustworthy application identity, and the platform must not promote them to the stream fields the parent scopes application logs by. The guest release replaces the monitoring-agents filters and outputs wholesale, which is what keeps the parent's label lift out of guests; pin that so a later change to the guest overrides cannot bring it in. This only covers what the platform ships. A guest admin can still edit the guest's fluent-bit or write to the parent's vlinsert directly; that needs a write-path control, which the logs proposal leaves open.

Walkthrough

The Fluent Bit configuration lifts Kubernetes labels and routes three application lineage fields in root and tenant container-log outputs. Tests check those fields, confirm events and audit outputs omit them, and verify the guest release uses pod, container, and namespace fields without lineage-label processing.

Changes: Monitoring-agent identity fields

Layer / File(s)	Summary
Lift and route lineage fields `packages/system/monitoring-agents/values.yaml`, `packages/system/monitoring-agents/tests/fluent-bit_application_identity_test.yaml`	The kube-log filter lifts Kubernetes labels and renames application group, kind, and name. Root and tenant container-log outputs include those fields in `_stream_fields`. Tests check the filter order and confirm events and audit outputs omit the lineage fields and are not matched by label lifting.
Check guest identity fields `packages/apps/kubernetes/tests/monitoring_agents_application_identity_test.yaml`	The guest-release test checks for pod name, container name, and namespace in output `stream_fields`. It also rejects label lifting and application-identity patterns in guest filters and outputs.

The new application fields can contain workload-supplied values and should not be treated as authoritative identity. With that limitation understood, the change is mergeable; the suggested test guards improve regression protection.

Full details: Title check

Explanation

The title "feat(monitoring-agents): keep application identity in container log streams" matches the main change in the changeset. The diff lifts and renames the pod lineage labels apps.cozystack.io/application.{group,kind,name} and adds them as stream fields to the default and per-tenant container-log outputs in the monitoring-agents values. The title names the component (monitoring-agents) and the primary effect (identity kept in container log streams). The related tests for monitoring-agents and the guest kubernetes release support this change.

Add a guard that rejects Labels Off in the kubernetes filter.

The new assertions check only the order of the lift, rename, and stream-field statements. None of them covers the kubernetes filter block. If Labels Off is added to that block, all three assertions still pass. Fluent Bit then omits the pod labels, and the apps_cozystack_io_application_* stream fields are no longer produced. This is a test-coverage gap for the behavior this suite protects. The current configuration is not affected.

Assert the guest nest filter that produces kubernetes_pod_name.

The test checks only the rendered output uri. That string contains kubernetes_pod_name regardless of the filters. If the nest filter's Wildcard pod_name lift or its Add_prefix kubernetes_ is removed, this test still passes. The guest stream then loses the pod field silently. Add two matchRegex checks on the filters.

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The renames promote pod labels directly into application identity stream fields. If a workload owner can set or subsequently change those lineage labels without the lineage webhook enforcing their values, that owner can attribute its logs to another application.

The other application's scoped log view could display attacker-controlled log entries.

This can occur when: A workload owner creates or updates a pod with lineage label values belonging to another application.

Maxim Kitsunoff (@kitsunoff) LGTM. The container-log, guest, and events/audit guards pass. I checked the pinned Fluent Bit implementation and ran the Helm suites; I did not run Fluent Bit against a live cluster.

Business context: application-scoped log queries need indexed lineage fields on container logs without changing guest, event, or audit streams.

## 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.

follow-up: ### 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. ```

## 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). -

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. ### Screenshots No UI changes. ### Downstream repositories - [ ] No downstream repository is affected by this change - [ ] [cozystack/website](https://github.com/cozystack/website) - follow-up: - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [ ] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: - [ ] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: 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.
