edeliver v1.8.0 Edeliver.Relup.Instructions.Info

This upgrade instruction logs the given info message on the node which runs the upgrade

and in the running upgrade script which was started by the $APP/bin/$APP upgarde $RELEASE command. Usage:

  Edeliver.Relup.Instructions.Info.modify_relup(config,
      _up_message="Synchronizing nodes",
      _down_message="Desynchronizing nodes",
      _insert_where = &append_after_point_of_no_return/2)`

Available sections are:

  • :check -> Checks whether upgrade is possible. Before "point of no return"
  • :suspend -> Suspends processes before the upgrade. Right after the "point of no return"
  • :upgrade -> Runs the upgrade by (un-)loading new(/old) code and updating processes and applications
  • :resume -> Resumes processes after the upgrade that were suspended in the :suspend section.
  • :finished -> The upgrade finished successfully
