Deploying a High Available Kubernetes Cluster

The playbook deploys a highly available Kubernetes cluster by performing the following tasks:

• Creating a temporary directory (/tmp/k8s) to store certificates
• Installing kubelet, kubectl, and kubeadm on masters, workers, and ingress nodes
• Setting up CRI on all nodes
• Installing an ETCD cluster with TLS on master nodes
• Initializing the first master node using kubeadm and creating cluster certificates
• Adding remaining master nodes to the cluster
• Installing CNI for network configuration
• Adding worker nodes to the cluster
• Setting up HAProxy as API load balancer
• Configuring the ingress controller
• Setting up Helm for package management."
