How to not autostart docker-container with systemd

Help
1

The issue is that docker-containers start by default with systemd. I would like to disable the default behavior so that I can set a timer when the container starts.

What I’ve tried is to override the default wantedBy option to empty list, startAt to a specific time and set the serviceConfig.Restart to on-failure. But it still starts when I rebuild the system and than runs once.

I’m using version 20.03.

systemd.services.docker-CONTAINER_NAME = {
  serviceConfig.Restart = mkForce "on-failure";
  startAt = "02:00:00";
  wantedBy = [];
};

Could you post how you added docker-CONTAINER_NAME as well as the generated .service file?

@XXLPitu probably wantedBy = lib.mkForce [];?

Here is a minimal example

docker-containers.image = {
  image = "image";
  imageFile = pkgs.dockerTools.buildImage {
    name = "image";
    tag = "latest";
    created = "now";
    
    config.Cmd = [ "${pkgs.hello}/bin/hello" ];
  };
  log-driver = "journald";
};

systemd.services.docker-image = {
  serviceConfig.Restart = lib.mkForce "no";
  startAt = "02:00:00";
  wantedBy = [];
};

docker-image.service
