I want to create a Kubernetes cluster using Kubespary. I have created three nodes. I am using the official documentation: https://kubernetes.io/docs/setup/production-environment/tools/kubespray/ I have three remote virtual machines running openSUSE, serving as nodes.
After running the following command
ansible-playbook -i inventory/local/hosts.yaml -u root --become --become-user=root cluster.yml I get the result. Error:
