deployment-patterns

Standardizing release processes with Docker and CI/CD involves applying repeatable deployment patterns like rolling, blue-green, and canary releases. These patterns reduce deployment risk and toil by providing structured steps for building, testing, and releasing web services consistently.

Configuring a rolling deployment involves setting up a gradual rollout process where new service instances replace old ones incrementally. Built-in health checks verify each new instance is ready before continuing the rollout, and a fallback rollback strategy is included if the health checks fail.

Use blue-green or canary deployments for safe releases when you need to minimize downtime and risk. Blue-green switches traffic between two identical environments, while canary gradually routes a subset of users to the new version to test production readiness before a full rollout.

Yes, this deployment approach supports automated rollback strategies. Each pattern includes fallback mechanisms triggered by failed health checks, allowing you to revert to the previous stable version quickly and safely during a failed release or production issue.

Yes, you can use these deployment patterns for any Dockerized web service. They are applicable to building, testing, and releasing web services, and include production-readiness checklists to ensure your specific service meets the necessary criteria before deployment.
