Dockerfile that builds with poetry

[DMRobertson]

To test:

DOCKER_BUILDKIT=1 docker build . -t sydent && docker run -p 8090:8090 sydent

I've seen this print sydent's startup lines and persist data to the /data volume. I could make a GET request to localhost:8090/ and got a 404 error page for my troubles, together with an entry in Sydent's log. I haven't tested this any more thoroughly than that.

To inspect the container while it's running, get the container id with docker ps and then:

$ docker exec -it 001f9bfc6a54 bash
sydent@001f9bfc6a54:/home/sydent$ ls
src  venv
sydent@001f9bfc6a54:/home/sydent$ ls src
README.rst  poetry.lock  pyproject.toml  requirements.txt  res scripts  sydent
sydent@001f9bfc6a54:/home/sydent$ ls venv
bin  lib  pyvenv.cfg

Pull Request Checklist

• [ ] Pull request includes a changelog file. The entry should:

  • Include 'Contributed by Your Name.' or 'Contributed by @your-github-username.' — unless you would prefer not to be credited in the changelog.
  • Use markdown where necessary, mostly for code blocks.
  • End with either a period (.) or an exclamation mark (!).
  • Start with a capital letter.
• [ ] Pull request includes a sign off
