* NixFleet

  A complete, declarative and reproducible configuration of my entire Nix fleet, this includes the following machines:

  - my main home workstation ~pc~
  - homeserver (mainly a nas) ~hs~ *(to do, soon)*
  - my arm based [[https://wiki.pine64.org/wiki/Pinebook_Pro][PineBook Pro]] ~pbp~, almost completely open hardware
  - MacBook PRO that I use for work, for this I'll use [[https://github.com/LnL7/nix-darwin][nix-darwin]] keeping macOs 11 Big Sur *(to do, not soon)*

  The different confgurations share many profiles, in fact my original goal was to avoid to rewrite the same Nix derivations for my different machines.

** Commands
Here I describe my most used commands.
All the commands are executed inside the Flake's development shell.
To enter in this shell is sufficent to ~cd~ in the folder (if you use ~direnv~) or run ~nix develop~.

*** Checking
To check that the Nix Flake is [[https://nixos.org/manual/nix/unstable/command-ref/new-cli/nix3-flake-check.html#evaluation-checks][well defined]]:
#+begin_src shell
nix flake check
#+end_src

*** Building
#+begin_src shell
nix -Lv build ".#nixosConfigurations.<host>.config.system.build.toplevel"
#+end_src

Where ~<host>~ is the hostname e.g. ~pc~.

*** Testing new config
#+begin_src shell
bud rebuild <host> test
#+end_src

Where ~<host>~ is the hostname e.g. ~pc~.


*** Switching
#+begin_src shell
bud rebuild <host> switch
#+end_src

Where ~<host>~ is the hostname e.g. ~pc~.

*** Remote deploy
Using ~deploy-rs~ I guess, still finding out how to do.


** Github Actions
*** Check and build
At every commit pushed on ~master~ a Github actions which ~nix flake
check~ the flake is executed and then every system is build.
Currently this workflow will skip ~aarch64~ hosts since the runner is
~x86_64~ and I didn't find a way to make it cross compile.

*** Release
At every tagged commit whose tag name starts with ~release-~ a process
that release all the bootstrap ISOs for the systems is started.  Here
I've the same problem with ~aarch64~ hosts so the runner will skip
them.
