Background tasks in build environments

You can run background tasks in build environments. To do this, in your buildspec, use the nohup command to run a command as a task in the background, even if the build process exits the shell. Use the disown command to forcibly stop a running background task.

Examples:

• Start a background process and wait for it to complete later:

  |
  nohup sleep 30 & echo $! > pidfile
  …
  wait $(cat pidfile)

• Start a background process and do not wait for it to ever complete:

  |
  nohup sleep 30 & disown $!

• Start a background process and kill it later:

  |
  nohup sleep 30 & echo $! > pidfile
  …
  kill $(cat pidfile)
