Blue-green deployment patterns switch traffic between two identical environments, while canary deployment patterns route traffic incrementally to a new version to validate stability before a full rollout.

Plan a rollback strategy by defining health checks and readiness probes that automatically detect deployment failures, allowing you to revert to the previous stable container image and configuration.

Configure Docker health checks by defining readiness probes in your container build process, enabling your CI/CD pipeline to verify service availability before routing traffic during a rolling deployment.

Use canary deployments when releasing web applications with potential risk, allowing you to route a small subset of traffic to the new version and monitor health checks before completing the rollout.

The best way to orchestrate a rolling deployment is to structure your CI/CD pipeline to incrementally replace instances, using health probes to ensure environment configuration meets production readiness checks.
