Hi,

I’m having trouble with a GeoServer cluster in which we intend to use
GeoFence. For configuration updates (new layers, workspaces, general
configuration, etc.), initializing a reload via the GUI or via the REST-api
works perfectly, but not for GeoFence. A reload has no impact at all. I
assume that the reload does not work because of H2 DB locking. The only way
to get a configuration change from one instance to the next is shutting
down the instance where the changes were made (to release the DB lock) and
restarting the instance where you want the changes to be taken over to or
to apply the changes to multiple instances, but this would mean that the
configuration could be out of sync unless we write sync scripts. However, I
also noticed that after restarting instances something strange things
happen when new rules were written to multiple instances before.



In our case the cluster uses a shared configuration folder (NFS-share
mounted into the instances). We use the kartoza/geoserver docker image.



Does anyone have experience with using GeoFence in a cluster?

I tried to implement JMS based clustering but I was not successful in
getting this stable in our case. Would this solve keeping the GeoFence
configuration in sync?



Kind regards,

Olav
