Prerequisites to Publish a New Container Package

1. Create a Token

   • Generate a GitHub Personal Access Token (PAT) with write permissions on packages.

2. Initialize the Package with a Manual Push

   • Authenticate Docker with the token and push the image to initiate the package:

     echo '<your PAT>' | docker login ghcr.io -u <your GitHub username> --password-stdin
     docker push <your-image>

3. Request Repository Permissions

   • In the #working-tools channel, request the following:
     • Link the package to the repository.
     • Grant repository access for workflows to modify the package.
