For the general process and concepts see: https://docs.github.com/en/packages/working-with-a-github-packages-registry/working-with-the-container-registry
For our case I replaced the generic names with our own owner / repo / names / etc.
Run
docker login ghcr.io
When prompted use these:
- User: the github user
- Password: the github token
Update the timestamp (20240929) with the current date, ISO style:
docker build --tag ghcr.io/unicode-org/fedora-docker-gcr:20240929 -f Dockerfile_fedora .
docker push ghcr.io/unicode-org/fedora-docker-gcr:20240929
For more info see: https://docs.github.com/en/actions/use-cases-and-examples/publishing-packages/publishing-docker-images
and: https://stackoverflow.com/questions/64033686/how-can-i-use-private-docker-image-in-github-actions
To consider: generate and publish the docker image from a GitHub action.
The DOCKER_CONTAINER_USER_NAME and DOCKER_CONTAINER_REGISTRY_TOKEN used
in the action file for user and password are secrets already created.
They can be any GitHub user + token with the proper access rights. Right now this is a token of the icu-robot account.
