Hallucination Traps (Read First)

❌ Running database migrations and code deploy in the same step -> ✅ Migrate FIRST, deploy code SECOND (expand-and-contract)
❌ Deploying without a rollback plan -> ✅ Every deploy needs a tested rollback: previous Docker image tag or git revert
❌ Using latest tags in production container images -> ✅ Always use specific version tags or SHA digests

Deployment Procedures — Production Execution Mastery

1. Zero-Downtime Deployment Strategies

Stopping a server, pulling code, building, and restarting is unacceptable. This results in 30-120 seconds of 502 Bad Gateway errors.

Blue/Green Deployment

Two identical environments (Blue is live, Green is idle).
Deploy v2 to Green. Run smoke tests on Green.
Swap the reverse proxy (Nginx or Load Balancer) router from Blue to Green.
