Error occurred while creating a cluster using Kubespray
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/pro...ols/kubespray/
I have three remote virtual machines running openSUSE, serving as nodes.
After running the following command:
Code:
ansible-playbook -i inventory/local/hosts.yaml -u root --become --become-user=root cluster.yml
I get the result. Error:
