I need to maintain the docker-compose environment as I should update the
hosting environment and we wanna deploy the docker image.
The ecosystem is using docker, I use podman.
I therefore need to configure docker hub as look up registry for podman
for unqualified images.
There doesn't seem to be a `toTOML` nixpkgs method. That's why I write
the contents of the file myself.
It looks like the more up to date and established tool.
It looks like a faster tool.
It can be used by telescope neovim plugin to find files.
It supports an .ignore file in combination with .gitignore for more fine
grained setup.
I now already have nix shells as well as compose.yaml files for
projects. Those were split and are now migrated into a common folder.
That should keep main directory clean and self document that those files
relate to projects, not home manager or systems.
