--- name: remediation description: Safe remediation actions for Kubernetes. Use when proposing or executing pod restarts, deployment scaling, or rollbacks. Always use dry-run first. --- # Remediation Actions ## Safety Principles 1. **ALWAYS dry-run first** - All scripts support `--dry-run` flag 2. **Confirm before executing** - Show what will happen, ask for confirmation 3. **Document the action** - Log what was done and why 4. **Have a rollback plan** - Know how to undo the action ## Available Scripts All scripts are in `.claude/skills/remediation/scripts/` ### restart_pod.py - Restart a pod by deleting it ```bash # Dry run (shows what would happen) python .claude/skills/remediation/scripts/restart_pod.py -n --dry-run # Execute python .claude/skills/remediation/scripts/restart_pod.py -n ``` ### scale_deployment.py - Scale a deployment ```bash # Dry run python .claude/skills/remediation/scripts/scale_deployment.py -n --replicas N --dry-run # Execute python .claude/skills/remediation/scripts/scale_deployment.py -n --replicas N ``` ### rollback_deployment.py - Rollback to previous revision ```bash # Dry run (shows current and target revision) python .claude/skills/remediation/scripts/rollback_deployment.py -n --dry-run # Execute python .claude/skills/remediation/scripts/rollback_deployment.py -n ``` ## Remediation Workflow 1. **Diagnose first** - Use k8s-debugger to understand the issue 2. **Propose action** - State what you plan to do and why 3. **Dry run** - Show what will happen 4. **Get confirmation** - Ask user to confirm 5. **Execute** - Run the action 6. **Verify** - Check that the issue is resolved ## Common Remediation Scenarios ### Pod stuck in CrashLoopBackOff ```bash # 1. Check events python .claude/skills/infrastructure/kubernetes/scripts/get_events.py -n # 2. If fixable by restart, dry-run first python .claude/skills/remediation/scripts/restart_pod.py -n --dry-run # 3. Execute restart python .claude/skills/remediation/scripts/restart_pod.py -n ``` ### Deployment stuck with bad image ```bash # 1. Check history python .claude/skills/infrastructure/kubernetes/scripts/get_history.py -n # 2. Dry-run rollback python .claude/skills/remediation/scripts/rollback_deployment.py -n --dry-run # 3. Execute rollback python .claude/skills/remediation/scripts/rollback_deployment.py -n ``` ### Service under high load ```bash # 1. Check current state python .claude/skills/infrastructure/kubernetes/scripts/describe_deployment.py -n # 2. Dry-run scale up python .claude/skills/remediation/scripts/scale_deployment.py -n --replicas 5 --dry-run # 3. Execute scale python .claude/skills/remediation/scripts/scale_deployment.py -n --replicas 5 ``` ## Output Format When proposing remediation, use this structure: ``` ## Proposed Remediation **Action**: [e.g., Restart pod, Scale deployment, Rollback] **Target**: [resource name and namespace] **Reason**: [why this action will help] **Risk**: [potential side effects] ### Dry Run Output [output from --dry-run] ### Confirmation Required Please confirm you want to proceed with this action. ```
