## Summary - Set `replicas: 2` with `maxUnavailable: 0` / `maxSurge: 1` on CV and Docs deployments so rolling updates never drop below 2 ready pods - Add PodDisruptionBudgets (`minAvailable: 1`) to protect against node drains and cluster maintenance - Add Fly.io cache purge step to `cv-deploy.yaml` workflow (docs already had this) so CV deploys don't serve stale cached content ## Deployment and Testing - [ ] `argocd app diff cv` / `argocd app diff docs` from branch - [ ] Deploy from branch: `argocd app set cv --revision feature/ha-cv-docs-zero-downtime && argocd app sync cv` - [ ] Verify 2 pods running: `kubectl get pods -n cv --context=minikube-indri` - [ ] Test rolling restart: `kubectl rollout restart deployment/cv -n cv --context=minikube-indri` - [ ] During rollout, confirm continuous availability via `curl -I https://cv.eblu.me` - [ ] After merge: reset ArgoCD to main, re-sync both apps Reviewed-on: https://forge.ops.eblu.me/eblume/blumeops/pulls/273
