I signed up artichoke organization for the beta. Once activated, build and push an image:

docker build . -t artichoke-ci-base
docker tag artichoke-ci-base docker.pkg.github.com/artichoke/artichoke-ci/base:0.1
docker push docker.pkg.github.com/artichoke/artichoke-ci/base:0.1

To address warnings when building mruby-sys (I think from rust-bindgen)

Add CircleCI config to lint the sources in this repo, build the Dockerfile, and publish to the package registry.
