How to build

• [Optional] Log in to ghcr.io for build cache

  $ echo $GHCR_PAT | docker login ghcr.io -u USERNAME --password-stdin

  Login Succeeded

Note: without this step, you'll see messages like when building:

#9 importing cache manifest from ghcr.io/djbender/core:jammy-cache
#9 ERROR: failed to configure registry cache importer: failed to authorize: failed to fetch anonymous token: unexpected status: 401 Unauthorized

• docker buildx bake -f core/jammy/docker-bake.hcl
• or if you get an error PWD=$(pwd) docker buildx bake -f core/jammy/docker-bake.hcl

Development

We use ruby , and erb templates to generate our Dockerfile's

• Install ruby, (chruby, or asdf)
• bundle install
• bundle exec rake -T to see rake tasks

You can install some useful git-hooks by install overcommit

• gem install overcommit
• cp .overcommit.sample.yml .overcommit.yml
• overcommit --install
