- Login to Dev_Machine using root credentials and run the command
- after few minutes the script will install the required packages and completes the installation
- change the permissions of k3s config file
chmod 644 /etc/rancher/k3s/k3s.yaml
4. check the k3s service status using systemctl
5. check the status of nodes
5. check the kubectl verstion and status of Pods
