Hi, Two remarks from my side: 1. CloudMembershipService is not so usable, and seems to originally target OpenShift. To make it work you need to create ServiceAccount and give read permission for listing all pods in namespace. This seems to be missing in your case. It also has some assumptions about namespaces and naming of k8s manifests/objects.
2. DNSMembershipService is much easier to use, I suggest you to have a look at this instead: https://tomcat.apache.org/tomcat-9.0-doc/api/org/apache/catalina/tribes/membership/cloud/DNSMembershipProvider.html For this Membership Provider you only need to add headless Service manifest, I.e. ClusterIP: none. Mfg Thomas Am 14.
