Description Dirk Wiesenthal

Not all Apps add a running service to UCS. Some are "finished" after the Join Script is run, the portal is extended or a listener is registered.

The App Center supports these scripts, but does not support to ship only those: An App has to have

1) A repository and a package
or
2) A (running) Docker Container

Maybe we could add a new type of App to support

a) Only run the appropriate scripts (e.g., the ".inst" script)
or
b) Have a Docker Container, but only start it when necessary


b) could make this possible: An App with only a listener_trigger script where the container is only started if certain LDAP changes were made:

A
udm users/user create ...
eventually leads to
docker run --rm ... listener_trigger
