@hayd started a while https://github.com/hayd/deno-docker

This can be ported to be integrated as the Official Deno docker image. So 3 steps are needed:

• Integrate generation of docker image in the CI
• Test the generated docker image
• Publish image on the docker hub / github hub on release

Also do we plan to release on docker hub only or we push it to github registry also? It's just a matter of URL in the command in the CI but @ry and @piscisaureus have to create / set credentials in the project.
