edeliver v1.2.7 Edeliver.Relup.Instructions.StartSection

This upgrade instruction starts a new section

and logs that info on the node which runs the upgrade and in the upgrade script started by the $APP/bin/$APP upgarde $RELEASE command. Usage:

  Edeliver.Relup.Instructions.StartSection.modify_relup(config, _section = :check)

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

It uses the Edeliver.Relup.Instructions.Info instruction to display the section information.
