Policy Health Check failed with multi-node cluster

Policy can not pass the health check on multi-node cluster.

Here is the policy pods. The policy was deployed on 2 nodes

Then I log into the drools container and run

http -a 'healthcheck:zb!XztG34' :6969/healthcheck

Got the following result. It says PAP cannot access the mariadb and PDP had a subsystem failure.

So I checked the network connection between contaiers

In the drools container, I executed the curl command to the endpoints. The results shows that the endpoints are routable.

To debug this issue, I did another test.

I deleted one node then install policy, do the health check. Everything is fine.
