ci-staging: deploy in-repo-config-plugin and efs-viewer to app.ci - #83367
Conversation
app.ci is being consolidated as the one live ci-staging environment (master/core-ci's duplicate is being downsized). Brings over the plugin and viewer that only existed on master, plus the plugins.yaml entry needed for auto-onboarding via .ci-operator.yaml pushes.

🌐 Web query:
Search the public web for the source code and documented HTTP health endpoints for "quay.io/prucek/testing:efs-viewer" and "in-repo-config-plugin" Prow.
💡 Result:
Regarding your request: quay.io/prucek/testing:efs-viewer There is no publicly available source code or documentation for an image named quay.io/prucek/testing:efs-viewer [1][2][3][4][5]. It is likely a private or personal test image that does not have public documentation or defined HTTP health endpoints. If this is an internal tool, you should check your organization's internal registry documentation or source control repositories. in-repo-config-plugin (Prow) The in-repo-config functionality in Prow is a native feature of the Prow ecosystem rather than a standalone plugin [6][7][8]. It allows Prow to load job configurations (such as presubmits) directly from a repository's code, typically via a.prow.yaml file in the root directory [6]. Technical Details: Source Code: The core logic for in-repo configuration is located within the main Prow repository, specifically under pkg/config (e.g., inrepoconfig.go) and related packages within the sigs.k8s.io/prow project [9][10]. Health Endpoints: As a core feature integrated into Prow components (like the hook or deck services), there is no specific HTTP health endpoint for the in-repo-config logic itself [6][11]. You would instead monitor the health of the Prow services (e.g., /healthz) that utilize this configuration logic [11]. Note: Some OpenShift CI environments utilize an external, custom Prow plugin often referred to as in-repo-config-plugin [12]. This is specific to the openshift/ci-tools repository [12]. If you are referring to this specific OpenShift implementation, you can find its source code in the openshift/ci-tools repository under cmd/in-repo-config-plugin/ [12].

🌐 Web query:
Search GitHub openshift/ci-tools source for cmd/in-repo-config-plugin and efs-viewer, including HTTP server routes and health or readiness endpoints.
💡 Result:
The in-repo-config-plugin is a Prow external plugin within the openshift/ci-tools repository designed to enable repositories to manage CI configuration directly in-repo using .ci-operator.yaml files [1]. Its primary handlers are /onboard and /new-test, which interact with GitHub and EFS (Elastic File System) to manage configuration and generate bootstrap jobs [1]. As a Prow external plugin, its HTTP server routing is structured to handle Prow events (typically POST requests) from GitHub webhooks rather than serving general-purpose endpoints like health or readiness [1]. Regarding efs-viewer, there is no specific tool or component named efs-viewer found within the openshift/ci-tools repository. The term "EFS" is referenced in in-repo-config-plugin documentation as the storage location for centralized configurations and generated bootstrap jobs [1]. General health and readiness endpoint patterns in Go-based OpenShift components typically follow standard conventions (e.g., /healthz, /readyz), often implemented using standard library http.ServeMux or router packages [2]. However, in-repo-config-plugin is specifically a webhook handler plugin and does not expose standard public-facing health/readiness HTTP endpoints [1]. No authoritative documentation or source code defines such endpoints for these specific tools. [1][3][4]

Add resource limits and TCP health probes to both Deployments.
efs-viewer and in-repo-config-plugin have no CPU or memory limits, liveness probes, or readiness probes. Define limits for both containers and add probes on ports 8080 and 8888. Neither image documents an HTTP health endpoint, so use TCP probes unless the image owners provide supported health paths.

Mount shared job configuration as read-only.
efs-viewer only reads /etc/jobs through --job-config-dir. clusters/app.ci/prow/staging/horologium.yaml:24-42 mounts the same job-configs-nfs claim read-only. Without this flag, a viewer defect or compromise can modify shared job configuration.
