  • Move standalone Kuadrant extensions (e.g. pipeline-policy) out of the operator CSV patch and into their own installable chart, charts/kuadrant-extensions, deployed as a separate Helm release
  • Add charts/kuadrant-extensions: deploys the extensions namespace, the user-supplied CRD via extensionCRD.yaml, RBAC (ClusterRole, ClusterRoleBinding, ServiceAccount) from chart templates, and a Deployment that connects to the operator's extension gRPC service using a projected ServiceAccount token (audience kuadrant-extensions, 1h expiry)
  • Remove the old 08-extensions-patch.yaml CSV-patching approach
  • install.sh / uninstall.sh: install/uninstall the new chart when -e is passed, instead of merging extension manifests into the instances install
  • values.yaml: add extensionsImage, extensionsNamespace, and extensionsName to configure the standalone deployment
  • RBAC and ServiceAccount are managed by chart templates and derive from
    {{ .Values.kuadrant.extensionsName }} — users only need to provide the extension CRD in extensionCRD.yaml
  • README: document the new install path, the -e flag, and that extensions require Kuadrant v1.6+ / RHCL v1.5+

Verification steps

  1. Run ./install.sh -e with kuadrant.extensionsImage set to quay.io/rh-ee-starabov/extensions:pipeline-policy (testing image).
  2. Confirm the kuadrant-extensions namespace, ServiceAccount, ClusterRole/Binding, CRD are created with names derived from kuadrant.extensionsName.
  3. Confirm the extension pod starts, authenticates to the operator's extension gRPC service using the projected ServiceAccount token, and reaches Ready.
  4. Run ./uninstall.sh and confirm the kuadrant-extensions release is cleanly removed.

Closes #113
Follow-up work will wire this new standalone extension deployment into CI in testsuite-pipelines.

📝 Walkthrough

Walkthrough

The change replaces operator CSV patching with a standalone kuadrant-extensions Helm release. It adds namespace, CRD, RBAC, and Deployment templates. The installer and uninstaller manage the release. The README documents manual and scripted installation.

Changes

Standalone extension deployment

Layer / File(s) Summary
Extension configuration and chart
values.yaml, example-extensionCRD.yaml, charts/kuadrant-extensions/...
The new chart uses configurable extension values. It renders the namespace, extension CRD, ServiceAccount, ClusterRole, ClusterRoleBinding, and restricted Deployment.
Installation and removal lifecycle
install.sh, uninstall.sh, .gitignore
The -e option installs the kuadrant-extensions chart as a separate release. The uninstaller removes this release before instances.
Deployment documentation
README.md
The README documents supported versions, required manifests, image values, manual Helm installation, and the -e option.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔴 Critical · up to a7f52

The new standalone extensions install path can delete extension CRDs and their custom resources during uninstall, creating a destructive data-loss risk; merge should be blocked until CRD cleanup is excluded or made explicitly opt-in. Version compatibility, configuration migration, multi-extension support, and authentication credential handling also require owner follow-up.

Poem

A rabbit checks the chart with care
New pods hop lightly through the air
CRDs and RBAC fall in line
Helm plants extensions, neat and fine
The old CSV patch fades away
And uninstall cleans the way

Explanation

The changes satisfy issue [#113]. They deploy extensions as standalone workloads, provision the namespace, CRD, RBAC, ServiceAccount, Deployment, and credential wiring, and remove the old CSV-patching mechanism.

Full details: Out of Scope Changes check

Explanation

The changes remain within scope. The documentation, installer updates, uninstaller updates, configuration changes, chart resources, and removal of CSV patching all support the standalone extension deployment objective.

In `@example-extensionsManifests.yaml`:

with kuadrant.extensionsName and its -credential resource with the same quoted
kuadrant.extensionsToken value; when that value is empty, reuse the previously
generated token on Helm upgrades before generating a new one.

In `@values.yaml`:
- Around line 73-77: Replace the single extensionsName configuration with a list
of extension definitions, then update the chart templates to range over that
list when rendering each extension’s Deployment, RBAC resources, credential
Secret, and authentication Secret entries. Update install.sh’s -e handling to
accept and install multiple configured extensions while preserving unique
resource and release names per extension.

Inline comments:
In `@charts/kuadrant-extensions/templates/02-extensionCRD.yaml`:
- Around line 2-5: Update the extension CRD handling around the extensionCRD
template and uninstall flow so these CRDs are not removed during normal release
deletion or broad kuadrant CRD cleanup. Manage them outside the Helm release and
exclude them from uninstall.sh’s automatic deletion filter, or require an
explicit destructive-cleanup action while preserving intentional cleanup
behavior.

In `@example-extensionCRD.yaml`:
- Around line 1-8: Update the Helm values/rendering flow around extensionCRD so
configurations using the former extensionsManifests key either migrate through
an alias or fail explicitly when extensionCRD is empty; prevent Deployment and
RBAC from rendering without a CRD when kuadrant.extensionsImage is set, and
audit existing installation values for the legacy key.

In `@values.yaml`:
- Around line 65-68: Set the values.yaml extensionsImage default to an empty
string so extensions remain disabled unless explicitly configured, preserving
the documented Kuadrant v1.6+/RHCL v1.5+ compatibility requirement.
