Containers

Containers package an app with its dependencies so it runs the same from a laptop to production. Good practice matters as much as the tools.

• Build with Docker, Podman, Buildah, Kaniko, or Crane.
• Keep images small, layered carefully, and scanned.
• Store images in a registry with versioning and access control.
• Wire builds into CI/CD so releases are repeatable.
• Orchestrate in production with Kubernetes when you need scale and scheduling.
