name devops-rollout-plan description Generate comprehensive rollout plans with preflight checks, step-by-step deployment, verification signals, rollback procedures, and communication plans for infrastructure and application changes DevOps Rollout Plan Generator Your goal is to create a comprehensive, production-ready rollout plan for infrastructure or application changes. Input Requirements Gather these details before generating the plan: Change Description What's changing (infrastructure, application, configuration) Version or state transition (from/to) Problem solved or feature added Environment Details Target environment (dev, staging, production, all) Infrastructure type (Kubernetes, VMs, serverless, containers) Affected services and dependencies Current capacity and scale Constraints & Requirements Acceptable downtime window Change window restrictions Approval requirements Regulatory or compliance considerations Risk Assessment Blast radius of change Data migrations or schema changes Rollback complexity and safety Known risks Output Format Generate a structured rollout plan with these sections: 1. Executive Summary What, why, when, duration Risk level and rollback time Affected systems and user impact Expected downtime 2. Prerequisites & Approvals Required approvals (technical lead, security, compliance, business) Required resources (capacity, backups, monitoring, rollback automation) Pre-deployment backups 3. Preflight Checks Infrastructure health validation Application health baseline Dependency availability Monitoring baseline metrics Go/no-go decision checklist 4. Step-by-Step Rollout Procedure Phases : Pre-deployment, deployment, progressive verification Specific commands for each step Validation after each step Duration estimates 5. Verification Signals Immediate (0-2 min): Deployment success, pods/containers started, health checks passing Short-term (2-5 min): Application responding, error rates acceptable, latency normal Medium-term (5-15 min): Sustained metrics, stable connections, integrations working Long-term (15+ min): No degradation, capacity healthy, business metrics normal 6. Rollback Procedure Decision Criteria : When to initiate rollback Rollback Steps : Automated, infrastructure revert, or full restore Post-Rollback Verification : Confirm system health restored Communication : Stakeholder notification 7. Communication Plan Pre-deployment (T-24h): Schedule and impact notice Deployment start: Commencement notice Progress updates: Status every X minutes Completion: Success confirmation Rollback (if needed): Issue notification Stakeholder Matrix : Who to notify, when, via what method, with what content 8. Post-Deployment Tasks Immediate (1h): Verify criteria met, review logs Short-term (24h): Monitor metrics, review errors Medium-term (1 week): Post-deployment review, lessons learned 9. Contingency Plans Scenarios: Partial failure, performance degradation, data inconsistency, dependency failure For each: Symptoms, response, timeline 10. Contact Information Primary and secondary on-call Escalation path Emergency contacts (infrastructure, security, database, networking) Plan Customization Adapt based on: Infrastructure Type : Kubernetes, VMs, serverless, databases Risk Level : Low (simplified), medium (standard), high (additional gates) Change Type : Code deployment, infrastructure, configuration, data migration Environment : Production (full plan), staging (simplified), development (minimal) Remember Always have a tested rollback plan Communicate early and often Monitor metrics, not just logs Document everything Learn from each deployment Never deploy on Friday afternoon (unless critical) Never skip verification steps Never assume "it should work"
