Release and Rollback Runbook

Standardize release gates, post-deploy checks, and rollback triggers to reduce operational risk.

Example rollback triggers

  • 5xx error rate spikes above 1%
  • Core API p95 latency doubles
  • Critical feature outage lasts more than 5 minutes

Pre-release checks

  • Build/test/link checks completed
  • Owners assigned (release/verification/monitoring)
  • Hotfix path and communication channel confirmed

15-minute post-release validation

runbook
1) Sample 3 critical URLs
2) Check 5xx/4xx ratios
3) Execute one key user flow
4) Decide immediate rollback if abnormal

Rollback log template

markdown
- Trigger: [what happened]
- Decision Time (KST): [YYYY-MM-DD HH:mm]
- Rollback Target: [deploy or revision]
- Owner: [name]
- Follow-up: [next action]

TL;DR

  • Use this section as a quick baseline for release/rollback operation.
  • Replace branch names, secrets, URLs, and thresholds with your team-specific values.

Prerequisites

  • Confirm repository and runtime access permissions.
  • Verify baseline commands (`install`, `build`, `test`) for local/CI.
  • Ensure environment variables, secrets, and deployment targets are up to date.

Steps

  1. Lock the change goal and scope in one sentence.
  2. Apply the core release/rollback operation changes in minimal commits.
  3. Capture validation logs and immediately update checklist/docs.

Validation

  • Confirm build/test pass reproducibly on the current branch.
  • Run manual sample checks on critical user/operation flows.
  • Cross-check ko/en docs and links for intent consistency.

Troubleshooting

  • Capture logs, request payloads, and environment values first on failures.
  • Narrow down by permissions, env vars, routing, and build artifacts.
  • Record temporary mitigation and root-cause fix separately.
