Kubernetes Cluster Installation through Kubeadm..

1. First we need to create EC2 instance i.e t2 medium for master node and t2 micro for worker node.

1. Run command on both master and worker node..

sudo apt update -y sudo apt install docker.io -y

sudo systemctl start docker sudo systemctl enable docker

sudo curl -fsSLo /usr/share/keyrings/kubernetes-archive-keyring.gpg https://packages.cloud.google.com/apt/doc/apt-key.gpg

echo "deb [signed-by=/usr/share/keyrings/kubernetes-archive-keyring.gpg] https://apt.kubernetes.io/ kubernetes-xenial main" | sudo tee /etc/apt/sources.list.d/kubernetes.list

sudo apt update -y sudo apt install kubeadm=1.20.0-00 kubectl=1.20.0-00 kubelet=1.20.0-00 -y

1. Run this command on master node.

   sudo su kubeadm init

   mkdir -p $HOME/.kube sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config sudo chown $(id -u):$(id -g) $HOME/.kube/config

   kubectl apply -f https://github.com/weaveworks/weave/releases/download/v2.8.1/weave-daemonset-k8s.yaml

   kubeadm token create --print-join-command

2. Run this command on worker node.

sudo su kubeadm reset pre-flight checks

-----> Paste the Join command on worker node with --v=5

Yeaaaaah successfully created Kubernetes cluster through kubeadm..
