NixOS

:::info Note that this module is not maintained by the woodpecker-developers. If you experience issues please open a bug report in the nixpkgs repo where the module is maintained. :::

The NixOS install is in theory quite similar to the binary install and supports multiple backends. In practice, the settings are specified declaratively in the NixOS configuration and no manual steps need to be taken.

General Configuration

{ config

}:
let
  domain = "woodpecker.example.org";
in
{
  # This automatically sets up certificates via let's encrypt
  security.acme.defaults.email = "acme@example.com";
  security.acme.acceptTerms = true;
  security.acme.certs."${domain}" = { };

  # Setting up a nginx proxy that handles tls for us

    };
    # You can pass a file with env vars to the system it could look like:
    # WOODPECKER_AGENT_SECRET=XXXXXXXXXXXXXXXXXXXXXX
    environmentFile = "/path/to/my/secrets/file";
  };

  # This sets up a woodpecker agent
  services.woodpecker-agents.agents."docker" = {

      WOODPECKER_BACKEND = "docker";
    };
    # Same as with woodpecker-server
    environmentFile = [ "/var/lib/secrets/woodpecker.env" ];
  };

  # Here we setup podman and enable dns
  virtualisation.podman = {
    enable = true;
    defaultNetwork.settings = {
      dns_enabled = true;
    };
  };

    allowedTCPPorts = [ 53 ];
