  1. Service plugin supports any number of nested commands.

  2. command - command to execute. There are no limitations on commands here. Here could be binary, PHP file, script, etc.

  3. process_num - default: 1, number of processes for the command to fire.

  4. exec_timeout - default: 0 (unlimited), maximum allowed time to run for the process.

  5. remain_after_exit - default: false. Remain process after exit. For example, if you need to restart process every 10 seconds exec_timeout should be 10s, and remain_after_exit should be set to true. NOTE: if you kill the process from outside and if remain_after_exit will be true, the process will be restarted.

  6. restart_sec - default: 30 seconds. Delay between process stop and restart.

  7. env - environment variables to pass to the underlying process from the config.
