Opencast updates with no downtime

[lkiesow]

It would be great to have a “read only” mode for the Stud.IP Opencast plugin in which the plugin keeps delivering media but does not allow users to upload media.

How this would work in Opencast:

• We create new set of Opencast servers (admin, presentation, worker)
• We turn off all old Opencast servers except presentation
  • You can still search for videos
  • The player is still available
  • Videos are still being delivered
  • You cannot upload or modify any data
• We install the new Opencast version on the new servers
• We update the DNS entries to point to the new servers
• The new system is up and running

For this to work well with Stud.IP, the plugin…

• needs a read-only mode
• may not fail if the /api/… endpoints are unavailable

This likely needs more details but would be incredibly handy to have.

Maybe even propagate maintenance mode from opencast to the lms plugin.

Maybe even propagate maintenance mode from opencast to the lms plugin.

Opencast Maintenance Mode should be reflected in an Endpoint in Opencast, Martin & I did something regarding this: opencast/opencast#6084 [The PR is discontinued]

may not fail if the /api/… endpoints are unavailable

@lkiesow how about LTI Auth? is the presentation node capable of performing / handling LTI auth (module)?
