Hi Joseph, Thank you so much! 😊 I will work further based on your provided clue.

Hi all, For below LP IPv6: stx-openstack app apply failed by time out waiting for the condition "grpc_status" https://bugs.launchpad.net/starlingx/+bug/1859641 I provided a patch which can fix the known issue in LP. However, it still failed later when starting rabbitmq pod. controller-0:~$ kubectl -n openstack get po NAME READY STATUS RESTARTS AGE ingress-c74489c96-jsb7n 1/1 Running 0 17h ingress-error-pages-5889bfcf6c-h8kl6 1/1 Running 0 17h mariadb-ingress-b5cd65f4b-sq46c 1/1 Running 0 17h mariadb-ingress-error-pages-6d8b79b74f-9zmpc 1/1 Running 0 17h mariadb-server-0 1/1 Running 0 17h osh-openstack-memcached-memcached-545668bdbd-9jkv2 1/1 Running 0 17h osh-openstack-rabbitmq-cluster-wait-wbnwp 0/1 Init:0/2 0 17h osh-openstack-rabbitmq-rabbitmq-0 0/1 CrashLoopBackOff 207 17h There are below error logs 2020-02-26T07:43:36.451103975Z stderr F ++ echo osh-openstack-rabbitmq-rabbitmq-0 2020-02-26T07:43:36.45142814Z stderr F ++ awk -F - '{print $NF}' 2020-02-26T07:43:36.454160452Z stderr F + POD_INCREMENT=0 2020-02-26T07:43:36.454757022Z stderr F + '[' 0 -eq 0 ']' 2020-02-26T07:43:36.454795721Z stderr F + exec rabbitmq-server 2020-02-26T07:43:36.849021551Z stdout F ERROR: epmd error for host osh-openstack-rabbitmq-rabbitmq-0.rabbitmq.openstack.svc.cluster.local: nxdomain (non-existing domain) In /etc/hosts file below, I just found localhost4, no localhost6.
