An Ansible playbook to prepare Kubernetes cluster with control plane and worker node.

Pre-requisites

Prepare ansible connection from ansible host to control plane and worker node. You can follow this document ansible setup to prepare the connection.

Clone this repository

su - ansible
git clone https://github.com/mohammadrony/kubernetes-cluster-setup-playbook.git

Update variable in playbook

Update the variables in kube control setup, kube node setup and post installation role.

Check ansible hosts file

Check hosts file for host-group and host-names with control plane and worker node host names. By default it would work as follows

[knodes]
vm-worker

Run Ansible playbook

ansible-playbook playbook.yml

• Find the config file for the cluster from Ansible control host's /home/ansible/kubeconfig file.
• Copy the config file to remote host's ~/.kube/config file.
