to the standard Ingress template for classes other than Traefik-prefixed and
direct openshift modes; in charts/plane-enterprise/README.md lines 98-107,
explicitly state that annotations are ignored for both direct openshift Routes
and Traefik.

Reverted the ingress class-gate widening in 7b2c7d5 — that one needs its own consideration rather than riding along with the OpenShift work, and is being tracked separately. What went back: What stayed: the nil-pointer fix on the same file. Impact on the OpenShift path: none. The one thing the revert does remove is the Regression suite re-run — |

Kubernetes fsGroup volume ownership management CSI fsGroupPolicy documentation existing PVC kubelet
💡 Result:
In Kubernetes, volume ownership and permission management via fsGroup is controlled by the interaction between the Pod, the Kubelet, and the CSI driver [1][2]. There are two primary mechanisms for managing these settings: 1. Kubelet-Managed (Default/Legacy) By default, or when using drivers that do not support advanced volume mounting, the Kubelet recursively modifies ownership and permissions of files within a volume to match the fsGroup defined in the Pod's securityContext [2][3]. The CSIDriver resource's fsGroupPolicy field governs whether this occurs [4][5]: - ReadWriteOnceWithFSType (Default): The Kubelet examines the volume and only applies changes if the fsType is defined and the access mode is ReadWriteOnce [4][3]. - File: The Kubelet attempts to apply changes regardless of fstype or access mode [5][3]. - None: The Kubelet does not attempt any modifications [5][3]. 2. CSI-Managed (Delegation) To avoid the overhead of recursive chown/chmod operations (especially on large or slow volumes), modern CSI drivers can take over this responsibility [2][6]. If a driver advertises the VOLUME_MOUNT_GROUP node capability, the Kubelet automatically delegates fsGroup management to the driver during the NodeStageVolume and NodePublishVolume calls [1][2][7]. When this delegation is active, the CSIDriver.fsGroupPolicy and Pod.fsGroupChangePolicy fields are ignored, as the driver is expected to apply the necessary permissions directly during the mount operation [2][6]. In summary, the Kubelet handles ownership unless the CSI driver explicitly supports and advertises the VOLUME_MOUNT_GROUP capability, which shifts that responsibility entirely to the driver [2][7].

Make PVC migration guidance conditional. The admitted Pod’s fsGroup and the volume driver’s ownership behavior determine whether Kubernetes updates existing PVC ownership. A PVC can remain owned by uid/gid 1000 and be unwritable by the SCC-assigned identity. Replace this safety claim with storage-class and driver-specific checks, and require migration tests on snapshots or clones of existing PVCs before production upgrades.

OpenShift Route spec path passthrough TLS termination path not supported official documentation
💡 Result:
In OpenShift, path-based routing is not supported when using passthrough TLS termination [1][2][3]. This is because the OpenShift router does not terminate the TLS connection and therefore cannot inspect the request to determine the path [1][4]. Official documentation confirms that attempting to use passthrough termination with a path is incompatible with the router's architecture [1][3][4]. When configuring a passthrough route, the path field should be left empty (or set to '') and the pathType should be set to ImplementationSpecific [1][3][5]. Technical validation logic within the OpenShift API server explicitly prohibits routes that specify both a path and passthrough TLS termination [4].

Reject passthrough TLS termination for path-based Routes.
The template always renders spec.path and accepts arbitrary $oc.termination. OpenShift rejects Routes that combine a path with passthrough, so this setting causes deployment failure. Validate that termination is edge or reencrypt, or render separate pathless passthrough Routes.

…te ingress OpenShift ignores the image's USER, assigns an arbitrary UID from the namespace's range, and validates the pod's own request with MustRunAsRange -- so a manifest asking for a specific runAsUser or fsGroup outside that range is rejected at admission. Today `securityContext.enabled=true` renders runAsUser/runAsGroup/ fsGroup 1000 on every workload, so nothing schedules; and neither ingress branch produces anything OpenShift's router can serve. securityContext needs no template change: setting a key to null in a values file removes it during Helm's coalescing, so the rendered context keeps runAsNonRoot, seccompProfile and the dropped capabilities while carrying no UID. That is now shipped as examples/values-openshift.yaml, which also un-pins the email service's uid 100, selects the OpenShift ingress path and forces the bundled datastores off. Also in this change: - templates/ingress-openshift.yaml: one route.openshift.io/v1 Route per path when ingressClass is "openshift", carrying haproxy.router.openshift.io/timeout (the router's 30s default severs /live/ WebSockets and /pi/ streaming). Declaring the Routes directly avoids depending on whether annotations survive the ingress-to-route conversion, which varies by OCP version. - ingress.yaml: fix `len of nil pointer` on ingress_annotations, which made ingressClass=nginx fail to render at all unless the key was set explicitly; and widen the gate from `eq "nginx"` to any non-traefik, non-openshift class, which is what the README already claimed and what "openshift-default" needs. - email and opensearch: their hardcoded UIDs are now nullable values, defaulting to the current literals. Every existing configuration renders byte-identically to master (default, traefik, securityContext.enabled, local datastores, air-gapped) -- verified with only the render timestamp and the chart-version label normalized. Not covered here: SCC admission and Route behaviour cannot be exercised on EKS and still need a CRC / OpenShift Local run. Requires the images from plane-ee #9018, which grant group 0 write access to their runtime paths. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…port PR Three findings, all valid: - email.deployment.yaml: with services.email_service.runAsUser set to null (the OpenShift path), the `with` block emitted no securityContext at all, so the email container silently lost runAsNonRoot, dropped capabilities and seccompProfile -- the one unhardened workload, and a PSA "restricted" reject on a non-OpenShift cluster. It now takes everything except runAsUser from the shared containerSecurityContext when securityContext.enabled is set, and overrides runAsUser only when a value is given. Those controls are not UID-specific, so there was never a reason to exclude them. - ingress-openshift.yaml: added the minioHost and rabbitmqHost Routes that templates/ingress.yaml renders for the bundled MinIO console (9090) and RabbitMQ management UI (15672), via an optional per-route `host`. Both stay gated on the corresponding local_setup, so neither renders in the recommended OpenShift configuration where the bundled datastores are off. (The Traefik template omits these too -- that pre-existing gap is left alone here.) - values.yaml / README.md: the ingress_annotations comment still claimed they are "ONLY rendered when ingressClass is 'nginx'", which this PR's widened gate made wrong. Restated as "every class except traefik* and openshift", and noted that Routes take ingress.openshift.route_annotations instead. Render check re-run against master. default, traefik+silo+pi+email, local datastores (now also with minioHost/rabbitmqHost set) and air-gapped are still byte-identical. The single intentional difference is securityContext.enabled=true, where the email container now gains allowPrivilegeEscalation: false, capabilities.drop [ALL], runAsNonRoot and seccompProfile alongside its uid 100. That is strictly additive hardening and safe: the service binds 10025/10465/10587, so it needs no capability. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…gress.yaml Backs out only the widened ingressClass condition. Rendering the standard Ingress for every non-traefik class changes behaviour for existing installs that set a class the chart never served, so it needs its own consideration rather than riding along with the OpenShift work. Tracked separately. templates/ingress.yaml goes back to `eq .Values.ingress.ingressClass "nginx"` verbatim. The nil-pointer fix on the same file STAYS: `gt (len .Values.ingress.ingress_annotations) 0` still aborts the whole render with `len of nil pointer` whenever ingressClass is nginx and the key is left commented out in values.yaml, which is unrelated to which classes are served. The OpenShift Route path is unaffected -- templates/ingress-openshift.yaml is its own template gated on `eq ... "openshift"`, so it never depended on the widened condition. What the revert does remove is the "openshift-default" alternative (letting OpenShift's ingress-to-route controller convert a plain Ingress); that class now renders nothing again, so every doc offering it as an option is corrected: values.yaml, README (both the template-selection table and the ingress_annotations row), examples/values-openshift.yaml and the header of ingress-openshift.yaml. A note on ingress.yaml records the README-vs-code mismatch for whoever picks this up. Verified against master: openshift-default, alb, haproxy and contour all render byte-identically again, alongside the existing default / traefik / local datastores / air-gapped cases. The single intentional difference remains securityContext.enabled=true, where the email container gains the shared hardening. nginx with no annotations still renders instead of erroring, and the openshift class still emits its Routes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…es.yaml
The securityContext block told you what it does but not how to configure it for
your platform, so the OpenShift case in particular was only discoverable by
reading the README -- and the mechanism there (setting the id fields to `null`)
is not something anyone guesses.
values.yaml now carries four copy-pasteable recipes at the point of use:
1. off (the default; entrypoints drop privileges themselves)
2. non-root uid 1000 -- just `enabled: true`
3. a platform-pinned uid, e.g. 10001
4. OpenShift / any platform that assigns the uid -- set runAsUser,
runAsGroup and fsGroup to null
Recipe 4 explains WHY null works (a null in a user values file removes the key
during Helm's merge, so the rendered context keeps runAsNonRoot, seccompProfile
and dropped capabilities but names no uid) and, more usefully, why the obvious
alternative fails: restricted-v2 validates with MustRunAsRange and rejects any
pod requesting an id outside the namespace's range, so leaving the 1000s in
place means nothing schedules at all. It also states the image requirement,
since older images crash under an assigned uid.
Also corrects the exclusions list: the email service no longer opts out of the
whole block, only of its uid -- it takes runAsNonRoot/capabilities/seccomp from
the shared settings as of the CodeRabbit fix earlier in this branch.
Comments only. All four recipes verified by rendering, and the default output is
still byte-identical to master.

Align the remaining ingress-class instructions.
This section correctly states that only traefik, openshift, and exact nginx activate chart templates. Lines [58] and [176] still say “or whichever class your controller exposes.” A user who sets alb or haproxy gets a successful install with no rendered ingress.

OpenShift 4.15 restricted-v2 SCC runAsUser fsGroup strategy MustRunAsRange MustRunAs official documentation
💡 Result:
In OpenShift Container Platform 4.15, the restricted-v2 Security Context Constraint (SCC) uses specific strategies to govern RunAsUser and fsGroup settings, primarily relying on namespace annotations for allocation [1][2]. RunAsUser Strategy The RunAsUser strategy for the restricted-v2 SCC is MustRunAsRange [1][2]. This strategy requires that the pod's user ID (UID) falls within a specified range [1]. In practice, because restricted-v2 is granted to authenticated users, OpenShift uses the openshift.io/sa.scc.uid-range annotation defined on the project (namespace) to automatically populate and validate the UID [1][2]. If a container does not explicitly request a UID, the effective UID is typically set to the first value in that project's allocated range [1][2]. fsGroup Strategy The fsGroup strategy for the restricted-v2 SCC is MustRunAs [1][2]. This strategy requires that the fsGroup must be defined and must match the allowed value [2]. Admission controllers look for the openshift.io/sa.scc.supplemental-groups annotation on the namespace to determine the authorized group ID [2][3]. If that annotation is missing, the system falls back to the openshift.io/sa.scc.uid-range annotation [2][3]. By default, this annotation-based strategy configures itself with a single range derived from the minimum value of the annotation [2][3]. Summary of Strategies - RunAsUser: MustRunAsRange [1][2] - fsGroup: MustRunAs [1][2] These configurations ensure that pods running under the restricted-v2 SCC are constrained to UIDs and GIDs allocated specifically to the namespace, maintaining security isolation between projects [1][2][4].

💡 Result:
In OpenShift, the restricted-v2 Security Context Constraint (SCC) utilizes the following strategies for fsGroup and supplementalGroups: 1. fsGroup: MustRunAs [1][2][3] 2. supplementalGroups: RunAsAny [3] Under the MustRunAs strategy for fsGroup, the SCC requires the pod to define a fsGroup that is validated against a range [1][2]. If the pod specification does not define an fsGroup, OpenShift typically uses the minimum value of the first range as the default [1][2]. When the strategy is MustRunAs, the system also checks the namespace annotation openshift.io/sa.scc.supplemental-groups to ensure compliance [1][2][4]. Under the RunAsAny strategy for supplementalGroups, there is no default provided, and the SCC allows any supplementalGroups ID to be specified by the pod [1][2]. The restricted-v2 SCC is designed to be highly secure, dropping all capabilities by default (with the exception of allowing NET_BIND_SERVICE) and enforcing strict security context settings [1][4][3]. It is the default SCC applied to pods for all authenticated users in modern OpenShift installations [4][3][5].

Describe the runAsUser and fsGroup strategies separately.
restricted-v2 uses MustRunAsRange for runAsUser and MustRunAs for fsGroup. State that runAsUser must match the namespace UID range, while fsGroup must match its separately configured group range or value.

OpenShift ignores the image's
USER, assigns an arbitrary UID from the namespace's range, and validates the pod's own request withMustRunAsRange— so a manifest asking for a specificrunAsUserorfsGroupoutside that range is rejected at admission. TodaysecurityContext.enabled=truerendersrunAsUser/runAsGroup/fsGroup: 1000on every workload, so nothing schedules; and neither ingress branch produces anything OpenShift's router can serve.The securityContext needs no template change
Setting a key to

That's now shipped asexamples/values-openshift.yaml, which also un-pins the email service's uid 100, selects the OpenShift ingress path, and forces the bundled datastores off.What else changed

Declaring the Routes directly avoids depending on whether annotations survive the ingress-to-route conversion, which varies by OCP version.

SCC admission and Route behaviour cannot be exercised on EKS and still need a CRC / OpenShift Local run. The images this depends on have been validated on a real cluster under an arbitrary UID — see internal-scripts#122.
