View Source Edeliver.Relup.Instructions.Sleep (edeliver v1.9.2)

This upgrade instruction is intended for testing only

and just sleeps the given amount of seconds. This can be used to test instructions which suspend processes at the beginning of the upgrade before the new code is installed. Usage:

  Edeliver.Relup.Instructions.Sleep.modify_relup(config, _seconds = 30)

It prints a countown in the upgrade script which was started by the $APP/bin/$APP upgrade $RELEASE command.
