Minimum Working Dockerfile

[NoRePercussions]

A mostly-functional Docker environment for tracker.

Some things this doesn't include:

• PDF generation (grover/puppeteer/chromium)
• Production environment
• Static asset serving documentation

The lifecycle of the development containers seems pretty automatable. What do you think about including some make targets for development?

I'd also personally like to include a healthcheck, but I don't want to deviate too far from the rails template.

We could, but ideally in the end I think it would condense down to:

docker compose up --file compose_dev.yaml
docker exec -it tracker rails c  # for initial member account

That way you don't even have to setup SQL. The compose_dev.yaml could build the repo locally and the compose.yaml (for production) would pull from the GitHub container registry.

I'd also personally like to include a healthcheck, but I don't want to deviate too far from the rails template.

When we reach Rails 7 there is this: https://edgeapi.rubyonrails.org/classes/Rails/HealthController.html

Great. I think I've addressed all comments, so what remains is whatever remaining comments you have.

It seems like after this PR, next steps in dockerizing may be

• Github actions for build check, run check
• Set up GHCR
• Setting up docker-compose dev env and everything that entails
• as well as continuing to work on salt interface for compose

Great! I have a standard GitHub action for dealing with GHCR I can push later tonight.

I think we should try to tackle #544 as a part of this. The current email process and Sphinx process are trivial to run in Docker Compose with the same container, but the Slack notification runs on a Systemd timer. That Systemd service can just become a docker exec but it would be better to be self-contained.
