GitHub Actions

A repository exploring GitHub Actions to automate Docker deployments.

Deployment targets

• Dockerhub - https://hub.docker.com/repository/docker/lotharschulz/hello-github-actions
• GitHub Container Registry - https://github.com/lotharschulz?ecosystem=container&tab=packages
• (GitHub Docker Registry - https://github.com/lotharschulz?ecosystem=docker&tab=packages)

Publish Docker Image to GitHub Container Registry

Publishing to GitHub Container Registry requires a @latest/developers/apps/about-apps#personal-access-tokens">personal access token with these scopes:

• repo (full access)
• write:packages
• delete:packages

Store the personal access token value in a repository encypted secret (e.g. CR_PAT)

Use the repository encypted secret in a workflow file: GCR_PASSWORD: ${{ secrets.CR_PAT }}

Find the published docker images in packages type container: https://github.com/[username]?ecosystem=container&tab=packages.
Please note: these images’ visibility is private.
