• Development notes

It takes time to build the image every time. On walter-ci, every push should create a new Docker image and push it somewhere so that we can prepare the entrypoint. Because of https://github.community/t/docker-pull-from-public-github-package-registry-fail-with-no-basic-auth-credentials-error/16358/58 we can't use Github Package Registry for that. Too bad.

We can run a (private) action to update the Docker image version every month.

Instead of a shell script we can just copy a jar, and put all Walter logic in this jar.

We keep the checkout as an external action to be explicit, but anything else will be handled inside Walter.

Use profiles.clj, deps.edn, and the great tooling from practicalli so that project.clj or equivalent deps.edn can be reduced to the minimum.
