local-docker-packaging

Automating local Docker packaging discovers build and bundle scripts, builds the image, and runs a docker save to export a tar artifact. This validates the output and assembles a delivery bundle to ensure repeatable local workflows.

Docker packaging automation works with Colima on macOS. It supports both Docker Desktop and Colima environments across diverse repositories, allowing you to build images and export tar artifacts seamlessly.

Handling oversized build contexts during Docker packaging involves using auto-detection of project scripts and reporting actionable diagnostics. The skill troubleshoots packaging issues to ensure the image builds and exports correctly.

You can specify a custom Dockerfile or build script instead of relying on auto-detection. The skill supports explicit usage of --build-script, --bundle-script, or --dockerfile to control the image build and tar export process.

To verify artifacts exist after building and bundling a Docker image, the skill validates outputs at each stage. It confirms the image tar and delivery bundle are present, reporting actionable diagnostics if validation fails.

A local Docker build might fail if the project-provided bundle script is missing or outputs invalid artifacts. The skill validates artifacts after each stage and provides actionable diagnostics to troubleshoot the packaging process.
