# nix-infra

nix infrastructure configuration for CCCHH.

For deployment we're using [infra-rebuild](https://git.hamburg.ccc.de/CCCHH/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`](./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.
