Issue

How to print the configuration used by DG Operator at startup?

Resolution

Below configuration is added on the Infinispan CR

Add logging category org.infinispan.SERVER: debug to print the complete configuration at startup - i.e. the server config will be output to the logs - in the Infinispan CR.

    logging:
      categories: 
          org.infinispan.SERVER: debug

The pod logs will bring:

$ oc logs dg-cluster-test-0

Warning

Be careful that the configuration above shows DNS-PING however, the protocol used is in fact DNS_ping:

<dns.DNS_PING dns_query="<custom-cr>-ping.<namespace>.svc.cluster.local"
                      dns_record_type="A"
                      stack.combine="REPLACE" stack.position="MPING"/>

Root Cause

See the chapter DG Operator 8.4 Guide - Logging for more details.
