Hi, thanks for the example with horizon. Do you know what is the proper way to terminate horizon in this case? If we want to deploy a new worker, docs says we just have to run horizon:terminate and it will be restarted by supervisor. In k8s case seems like we need to delete pod first by running horizon:terminate and then create a new pod with artisan:horizon. Is that right? How did you do that?

@kolinko-ant I'm trying like this

  name: horizon-worker
spec:
  replicas: 3
  template:
    metadata:

          lifecycle:
            preStop:
              exec:
                command: ["/usr/local/bin/php", "artisan", "horizon:terminate"]
