Docker and & Docker Compose workflow detailed in README.md not working

[jasonmishi]

Issue description

It seems like the docker based set-up for development documented in the README doesn't work

$ docker-compose up
[+] Building 0.1s (1/1) FINISHED                                                                                                                                                                      docker:default

failed to solve: failed to read dockerfile: open Dockerfile: no such file or directory

Possible cause

I think the Docker file has been deleted accidentally in a previous commit.

Proposed solution

Instead of deleting the docker support I think we should bring it back to enable devs who are able to use docker both on nixos and more importantly other systems.

• I already created a Pull Request

Found a couple of commits that have lead to this current situation:

1. 2b4fc22 deletes both the Dockerfile and docker-compose.
2. 574ab2c adds back the docker-compose but not the Dockerfile.
