k8s/README.md says these manifests are the dry-run/reference copy of what Pulumi actually deploys, so they only earn their keep while they match. ol-infrastructure now sets a pod securityContext (runAsNonRoot, uid/gid 1000, fsGroup, seccomp RuntimeDefault), a container securityContext (no privilege escalation, read-only root, all capabilities dropped) and the /tmp emptyDir that the read-only root requires; this brings the reference copy in line.

What
Adds the pod/container
securityContextand the/tmpemptyDir tok8s/deployment.yaml.Why
k8s/README.mdis explicit that these manifests are the local dry-run / reference copy of what Pulumi actually deploys — which only earns its keep while it matches. mitodl/ol-infrastructure#5410 adds:securityContext(runAsNonRoot, uid/gid 1000,fsGroup: 1000, seccompRuntimeDefault),securityContext(allowPrivilegeEscalation: false,readOnlyRootFilesystem: true,capabilities.drop: [ALL]),/tmpemptyDir, the one writable path the read-only root still needs.This brings the reference copy in line. No behavior change in this repo — nothing here is deployed from these manifests.
How tested
kubectl apply --dry-run=client -f k8s/deployment.yaml— accepted.prek run --files k8s/deployment.yaml— all hooks pass.🤖 Generated with Claude Code
