Klaus

The recommended method for deploying Klaus according to the developer is using uWSGI or Gunicorn. This article provides an example deployment using uWSGI.

services.uwsgi = {
    enable = true;
    plugins = [ "python3" ];
    instance = {
        type = "normal";
        master = true;
        http-socket = ":8080";
        module = "klaus.contrib.wsgi:application";
        chdir = pkgs.klaus;
        pythonPackages = self: with self; [
            klaus
            markdown # adds markdown support, optional
        ];
        env = [
            "KLAUS_REPOS=/repos/repo1 /repos/repo2"
            "PATH=${pkgs.git}/bin" # klaus makes a direct call to git
        ];
    };
};

When loading a repository, you may encounter a 500, traced back to a git command call in the uWSGI logs. Try setting services.uwsgi.user and services.uwsgi.group to match the ownership of the repository.

Autoreloading

By default, Klaus will only be able to to track the repos specified in the KLAUS_REPOS environment variable. In order to have it keep track of a set of unknown repos, Klaus needs to be configured to autoreload.

services.uwsgi.instance = {
    module = "klaus.contrib.wsgi_autoreload:application";
    enable-threads = true;
    lazy-apps = true;
    env = [ "KLAUS_REPOS_ROOT=/repos" ];
};
