NixOS Container¶

Setting up a basic nixos container within proxmox, and optionally configuring docker.

Resources¶

• NixOS Proxmox Docs

How To¶

1. Download the container template in proxmox by following the instructions on the wiki
2. Create the CT using the new template and start the container
3. The password you set in the proxmox webui doesn't work, so change the password doing the following in the proxmox shell (not the container shell)

   $ pct enter <ct_id>
   $ source /etc/set-environment
   $ passwd
   

   Then enter your new password.
4. Create your configuration.nix

   $ nano /etc/nixos/configuration.nix
   

5. Paste in the configuration found on the nixos wiki.
6. Rebuild the configuration

   nix-channel --update
   nixos-rebuild switch --upgrade
   

Optionally Install Docker¶

1. Create a docker.nix file alongside your configuration

   nano /etc/nixos/docker.nix
   

2. Paste in the following basic config

   { config, pkgs, ... }:
   
   {
   # Enable Docker
   virtualisation.docker = {
       enable = true;
       enableOnBoot = true;
   };
   
   # Install docker-compose as a system package
   environment.systemPackages = with pkgs; [
       docker-compose
   ];
   }
   

3. Rebuild the config nixos-rebuild switch --upgrade
