Tutorial - Setup a Phoenix application with Docker?

[SimonLab]

The "PETE" stack is using some languages/framework that evolve rapidly (ex: elm 0.18 to 0.19 recently, see also the list of the release versions for Phoenix https://github.com/phoenixframework/phoenix/releases).

Making sure that all the versions are up to date or at least that the dev team is running projects with the same versions is time consuming. For example on each new project I have to go back and read again the installation page for Phoenix (https://hexdocs.pm/phoenix/installation.html) to make sure that everything is setup properly.

I think Docker can help us to reduce the setup time for new projects but most importantly it can make sure that all the team is running exactly the same stack and data (especially making sure that Postgres contains the same data for everyone)

Goal: Create a guide which explain how to setup a "PETE" application with Docker that we can reuse each time a new project is started

@SimonLab yes, Docker can help with "pinning" dependencies in certain situations,
but it also adds a layer of complexity and overhead so our "learn-docker" needs to be super beginner-friendly while still covering the more advanced topics like "how to purge zombie containers"...

If you are able to do some research on this in the context of a phoenix project it would be good if you could also "cache" the Elm/Node dependencies for faster build on CI see: dwyl/learn-elm#116

Thanks for taking this on! ✨

There is a docker mastery course on Udemy which looks like it goes into all the details of docker that we could want or need. It seems like this will be a good way to get a great understanding quickly. It is available on the Founders and Coders Udemy account.

@RobStallion if you end up following the Udemy course, which by all accounts is good, 👍
Please consolidate the knowledge into the README.md to save everyone else time. ⏳
