Additional info


I use Podman with the NixOS module :


{
  virtualisation.oci-containers.containers.diun = {
    image = "crazymax/diun:4.33.0";

    environmentFiles = [
      "/mnt/stormwind/containers/envs/commun.env"
      "/mnt/stormwind/containers/envs/diun.env"
    ];

    extraOptions = [
    #  "--uidmap=0:1000:1"
    #  "--gidmap=0:100:1"
    #
      "--security-opt=label=type:container_runtime_t"
    ];
    cmd = ["serve"];

    hostname = "diun";
    networks = ["repiproxy:ip=10.89.0.24"];

    volumes = [
      "/run/podman/podman.sock:/var/run/docker.sock:ro"

      "/mnt/stormwind/containers/secrets/diun:/secrets:ro"

      "/mnt/stormwind/containers/volumes/diun-data:/data:U"
    ];
  };
}
