[Narinder Gupta]

Find out the right version of Kubernetes you can upgrade says 1.18.9 with Ussuri
Create a new template with the label --labels kube_tag=v1.18.9
openstack coe cluster template create k8s-cluster-template-1.18.9 --image fedora-coreos --keypair jumphost-key --external-network Magnum-Test --dns-nameserver 8.8.8.8 --flavor m1.small --docker-volume-size 5 --network-driver flannel --coe kubernetes --docker-storage-driver overlay2 --fixed-network Magnum-Test --fixed-subnet b2f76e60-2d39-4ac5-9c76-883db17c8fe0 --labels flannel_network_cidr=10.100.0.0/24 --label 'docker_volume_type=az1-stable2' --label 'boot_volume_size=20' --label boot_volume_type=az1-stable2 --labels kube_tag=v1.18.9

openstack coe cluster template create k8s-cluster-template-1.18.9 --image fedora-coreos --keypair ubuntu-keypair --external-network ext-net --dns-nameserver 8.8.8.8 --flavor m1.small --docker-volume-size 5 --network-driver flannel --coe kubernetes --docker-storage-driver overlay2 --labels kube_tag=v1.18.9

Run upgrade command with new template
openstack coe cluster upgrade test-cluster k8s-cluster-template-1.18.9

Gets an error when upgrade cluster is accepted. Fine out that heat not even tries to upgrade the cluster.
