ci-staging: unify job config sources on shared NFS volume - #83571
Conversation
Have git-sync write directly to the NFS PVC under /etc/jobs/git-synced/ instead of a separate emptyDir. All prow components now read both EFS plugin-written jobs and git-synced release-staging jobs from a single --job-config-path=/etc/jobs.

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The configuration change consolidates job sources on a writable shared NFS mount across five workloads, but those workloads still lack required container hardening, resource limits, and health probes. This creates a concrete security and runtime-readiness gap, so merge should wait for the configuration to be fixed or explicitly accepted by the owner. 🚥 Pre-merge checks | ✅ 15✅ Passed checks (15 passed)

Add the required container hardening and resource limits.
These Deployments do not enforce a pod or container securityContext. They also omit CPU and memory limits. The long-running git-sync containers have no liveness or readiness probes.
Set runAsNonRoot, readOnlyRootFilesystem, allowPrivilegeEscalation: false, and drop all capabilities. Add resource limits to every container. Add probes to long-running containers.
