   Cicd Pipeline · leomajewski

   Method and checklists for shipping a containerized application with GitHub Actions, Docker and Kubernetes — build once, publish a signed immutable image, promote that exact digest through gated environments to production. Covers the inventory to gather first, the dev/infra boundary, build-once/promote-by-digest, supply-chain integrity, deployment strategies, secrets, health-gated rollout, GitHub Environments approvals, and rollback. Use when asked to create or configure a pipeline, onboard an app to CI/CD, set up an environment, promote to production, or migrate a hand-run deploy to an automated one.
