Hi Team, I am trying to create kubernetes cluster using Magnum Openstack. My External Network configuration is as follows: neutron net-create MGMT_NET --shared --router:external --provider:physical_network provider1 --provider:network_type flat neutron subnet-create MGMT_NET 10.0.61.0/24 --name MGMT_SUBNET --allocation-pool start=10.0.61.10,end=10.0.61.250 --disable-dhcp --gateway 10.0.61.1 Then I am creating a template with docker storage driver as "Overlay" openstack coe cluster template create kubernetes-cluster-template --image fedora-atomic-latest --docker-storage-driver overlay --external-network public --dns-nameserver 8.8.8.8 --master-flavor m1.small --flavor m1.small --coe kubernetes Creating a cluster with 1 master node openstack coe cluster create kubernetes-cluster --cluster-template kubernetes-cluster-template --master-count 1 --node-count 1 --keypair key-pair When I look into my stack, it shows the event kube_masters <http://192.168.121.118/horizon/project/stacks/stack/58ddd64a-8779-495d-8d31-27f3615c8103/kube_masters/> Create in Progress and eventaully after 1 hr, it gets failed. I have checked the Troubleshooting Guide as well, but found nothing that could help me resolving the issue. https://docs.openstack.org/magnum/rocky/admin/troubleshooting-guide.html Can you please suggest some pointers in order to resolve the issue.
