nix-infra
nix infrastructure configuration for CCCHH.
For deployment we're using infra-rebuild.
To easily get a shell with infra-rebuild
going, use the following command:
nix shell git+https://git.hamburg.ccc.de/CCCHH/infra-rebuild#infra-rebuild
After that you can simply run the following to deploy e.g. the git and matrix hosts:
infra-rebuild switch git matrix
By default infra-rebuild tries to use the FQDN from the nixosConfiguration of the host for deployment.
However to override individual parts of the deployment target, a deployment_configuration.json
can be used.
This is exactly what we're doing to set the default deployment user to colmena-deploy
and have custom target hostnames for Chaosknoten hosts, since they don't have an FQDN defined in their nixosConfiguration.
Setting up secrets with sops-nix for a host
- Convert the hosts SSH host public key to an age public key.
This can be done by connecting to the host and running:
cat /etc/ssh/ssh_host_ed25519_key.pub | ssh-to-age
- Add the resulting age public key to the
.sops.yaml
as a YAML anchor in keys. It should be named something like:host_age_hostname
- Add a new creation rule for the hosts config directory.
It should probably have all admin keys and the hosts age key.
You can use existing creation rules as a reference. - Create a file containing the relevant secrets in the hosts config directory.
This can be accomplished with a command similar to this:
Note: Nested keys don't seem to be compatible with sops-nix.sops config/hosts/hostname/secrets.yaml
- Add the following entry to the modules of the hosts
nixosConfiguration
:sops-nix.nixosModules.sops
- Create a
sops.nix
in the hosts config directory containing the following content to include thesecrets.yaml
:{ ... }: { sops = { defaultSopsFile = ./secrets.yaml; }; }
- Make sure the
sops.nix
gets imported. For example in thedefault.nix
. - To use a secret stored under e.g.
forgejo_git_smtp_password
, you can then do something like the following:
This secret would then be available undersops.secrets."forgejo_git_smtp_password" = { mode = "0440"; owner = "forgejo"; group = "forgejo"; restartUnits = [ "forgejo.service" ]; };
/run/secrets/forgejo_git_smtp_password
on the host.
