Wildfly HA in Openshift

mbsakho Oct 10, 2019 8:26 AM

Hello everyone,

I'm using kubernetes.KUBE_PING protocole with wildfly 18 on openshift 3.11

I've configured JGroups subsystem with the following snippet:

/subsystem=jgroups/channel=ee:write-attribute(name=stack,value=tcp) /subsystem=jgroups/stack=tcp/protocol=MPING:remove /subsystem=jgroups/stack=tcp/protocol=kubernetes.KUBE_PING:add(add-index=0,properties={namespace="bms",labels="app=bms-latest")

The cluster works fine but I'm having the following warning in the server logs that is outputed infinitely:

13:51:14,177 WARN [org.jgroups.protocols.kubernetes.KUBE_PING] (thread-18,ejb,demo-latest-2-z2ptf) metadata.labels.pod-template-hash not found in pod json. Impossible to reliably determine pod group during Rolling Update

How can I get rid of this warning?

Regards,

Meissa

This is a known issue, should not impact the deployment. Follow [WFLY-12657] KUBE_PING too frequent warning metadata.labels.pod-template-hash not found in pod json. Impossible to relia… on Jira.

Thanks Radoslav,
I've got the same answer from Sebastian.
I'm waiting for the next patch or release then.
