Usage with Flakes
Installation
To quickly try Colmena out, use the following command to enter an ephemeral environment with the latest development version of colmena
:
nix shell github:zhaofengli/colmena
To install Colmena to the user profile, use the following command:
nix-env -if https://github.com/zhaofengli/colmena/tarball/main
You can also add github:zhaofengli/colmena
as an input in your Flake and add the colmena
package to your devShell
.
Unstable Binary Cache
A public binary cache is available at https://colmena.cachix.org, courtesy of Cachix. This binary cache contains unstable versions of Colmena built by GitHub Actions.
Basic Configuration
Colmena reads the colmena
output in your Flake.
Here is a short example:
{
inputs = {
nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
};
outputs = { nixpkgs, ... }: {
colmena = {
meta = {
nixpkgs = import nixpkgs {
system = "x86_64-linux";
overlays = [];
};
};
host-a = { name, nodes, pkgs, ... }: {
boot.isContainer = true;
time.timeZone = nodes.host-b.config.time.timeZone;
};
host-b = {
deployment = {
targetHost = "somehost.tld";
targetPort = 1234;
targetUser = "luser";
};
boot.isContainer = true;
time.timeZone = "America/Los_Angeles";
};
};
};
}
The full set of deployment
options can be found here.
You can also check out the example in the main tutorial for some inspiration.
Now you are ready to use Colmena! To build the configuration:
colmena build
To build and deploy to all nodes:
colmena apply
