Inhouse docker image builds

jinnatar commented 2 years ago

This hugely builds on the work by @ajacobson (https://github.com/ajacobson/chiadog-docker) and no disrespect is intended.

Proposing merge to main instead of dev since this does not in any way modify how Chiadog works and will then enable images to be built for any and all branches regardless of when dev is merged to main.

Major benefits of inhousing:

Can easily build any state of the repo regardless of branch or mid-development into a functional image without mucking about with an external repo. Doing other chiadog development made me frustrated enough to also fix this. :-)
Faster builds when the source code is already present without an extra clone
Automated Docker image builds into the free GitHub image repository. Official images triggered by official tags & releases, but also dev images any any other branch provide repeatable and traceable pinning of images.

Minor fixes added as well:

entrypoint.sh was missing a shebang
- Simplified entrypoint running now that the script has a proper shebang
- Simplified logic by switching WORKDIR earlier
- Add a .dockerignore file to prune dirty state and useless weight from the container.

Does not include:

Any documentation. Docker is an advanced option in any case but this should be added as a followup.

Oops, let me rebase this from dev -> main.

Example image has been automatically built in my fork: https://github.com/Artanicus/chiadog/pkgs/container/chiadog .. this shows the logic for non-special branches with the image name becoming: ghcr.io/artanicus/chiadog:inhouse_docker-26c7b8

@martomi PTAL, all feedback incorporated and everything simplified quite a bit.
