View Source Edeliver (edeliver v1.9.2)

Execute edeliver tasks on the production / staging nodes.

This internal module provides functions on the nodes which are used by some edeliver tasks e.g. to get the running release version (edeliver version), show the pending migrations (edeliver show migrations) or install pending migrations (edeliver migrate).

In addition it represents the edeliver application callback module and starts a process registered locally as Edeliver which's onliest purpose is to be able to detect whether the release was successfully started. This requires to start edeliver as last application in the release.
