All,
If you are havig issues with the CloudMembershipService, I would highly
recommend that you continue to have this discussion.
The original author (remm) was mostly targeting OpenShift (he works for
RedHat, so it's not a surprise) but it doesn't mean that its support
cannot expand to include other deployments.
If the DNSMembershipService is more appropriate for k8s-on-Azure, that's
fine, but if there is a community need (and especially if you are
willing to do the research and contribute code) we'd be happy to
accomodate you.

Hi,
I am trying to setup Tomcat clustering running in AKS, however the
standard settings don't seem to work.
As per the documentation I have setup following Cluster configuration in
server.xml inside my <Host> tag:
<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster">
<Channel
className="org.apache.catalina.tribes.group.GroupChannel">
<Membership
className="org.apache.catalina.tribes.membership.cloud.CloudMembershipService"/>
</Channel>
</Cluster>
But I received a 'Failed connection to
https://10.0.0.1:443/api/v1/namespaces/tomcat/pods' error. Is there any way
to resolve this?
Error message:
