how could I add a delay, in seconds, at the beginning of the script, so the script waits 20 secs after array start before launching the docker compose?

thanks in advance

You could try adding sleep(20); on line 23 but this would always add a delay to the script. I'm also not sure if it would make the script time out. Give it a go and see if it works for you.
