A Dockerfile and other stuff to quickly create a smallish container for utility work. This is totally specific to me. If you have suggestions on how I do things, please send them; if it's about what I include, don't.
This adds a new non-root superuser to the image. You can edit the Dockerfile defaults or use --build-arg on the build.
The ARGS include USER, GROUP, UID, GID, and SHELL.
See the Dockerfile for added tools I like to have around for developing. Lots of other stuff gets installed via dependencies.
I git clone my .dotfiles and use stow to symbolic-link them to my home directory.
