minimalish docker image

minimalish docker image building.

export NAME=projectName
export VERSION=$(git rev-parse HEAD)
export CONFIGDIR=/path/to/config
docker load < $(nix-build -A dockerImage --no-out-link --argstr name $NAME --argstr version 
$VERSION )
docker run -p 127.0.0.1:8000:8000/tcp -v "$CONFIGDIR:/var/run/backend/config' "${NAME}:${VERSION}"

I would suggest avoiding runAsRoot if at all possible, because using it means constructing the Docker image with QEMU, which is slower than using extraCommands or something along those lines.

Can we make this more composable? I.e. by exposing the building blocks?

What needs to happen for us to remove the WIP?

Wanted to verify that it worked for a few people. It does. I think this is Good Enough™.

Like I said, I'd like to see the guts of this at least pulled out into a function so I can get the "how to create the image" without the image itself. Then I can customize the image if I need to (which is likely).

version is required - would it make sense to make it optional and default to latest ?

I tested the latest version of the PR locally using NixOS 19.03 and works really well - awesome job!
