Docker-Compose and Other Docker Images

[heywoodlh]

For https://github.com/Yetangitu/Spodcast/issues/15

Per my testing, the docker-compose.yml file works out of the box with the following caveats:

• https://github.com/Yetangitu/Spodcast/issues/17
• https://github.com/Yetangitu/Spodcast/issues/16

Significant Changes:

• I have moved all my Dockerfiles related to Spodcast into the docker directory. That way we have a single source of truth for Spodcast's Docker stuff -- rather than having to point to my Dockerfiles repository.

• I have added individual Dockerfiles for the following images:

  • heywoodlh/spodcast
  • heywoodlh/spodcast-cront (This image runs cron within the container so Spodcast can run on a schedule independent of the Docker host)
  • heywoodlh/spodcast-web

• Docker-compose.yml has been added

• Updated the README on how to use the new docker-compose.yml file.

Before Merging

I think that we should resolve https://github.com/Yetangitu/Spodcast/issues/17 and https://github.com/Yetangitu/Spodcast/issues/16 before this PR gets merged.

@Yetangitu any chance you'll have some time soon-ish to look at this and the issues I linked?

@heywoodlh thanks for this PR! I got it working on my end pretty flawlessly. Now I'll allegedly be able to listen to Spotify-only podcasts on Google Podcasts 🎉

(a somewhat belated) Merged, thanks
