Summary

  • Adds read-only rollout diagnostics CodeBundle for Kubernetes Deployments (Issue Image pull backoff check #121, parent Add Bot Config #120)
  • Eight tasks cover rollout status, ReplicaSet comparison, new-RS pod failures, strategy config, PDB impact, blocking events, stuck terminating pods, and revision history
  • Uses cron-scheduler SLI pattern for periodic triage execution; remediation deferred to k8s-deployment-ops

Scorer

python -m scorer.score codebundles/k8s-deployment-rollout-troubleshoot
Score: 104/104 (threshold: 70) — PASSED

Test plan

  • Apply .test/kubernetes/manifest.yaml to a kind cluster (task build-infra)
  • Run bundle against healthy-rollout — expect 0 issues on status task
  • Run against progress-deadline-fail — expect ProgressDeadlineExceeded issues
  • Run against pdb-blocked-rollout — expect PDB eviction blocking issues
  • Run against image-pull-fail — expect ImagePullBackOff on new RS pods
  • Validate generation rules via task validate-generation-rules in .test/

Made with Cursor
