INSTALLATION

1. Execute the commands below to install the required kubernetes software in all the three machines

   1. 

      sudo su

       

       

   2. 

      sudo apt-get update

      sudo apt-get install -y apt-transport-https ca-certificates curl

       

       

   4. 

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

       

       

       

       

   5. 

      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

       

       

       

       

   6. 

      sudo apt-get install -y kubelet=<Kubernetes_Version> kubeadm=<Kubernetes_Version> kubectl=<Kubernetes_Version>

       

       

       

      1. Example: sudo apt-get install -y kubelet=1.19.0-00 kubeadm=1.19.0-00 kubectl=1.19.0-00

   7. 

      apt update

       

       

   8. 

      apt install docker.io -y

       

       

2. Execute the commands below to provision Kubernetes Control plane on the master machine

   1. 

      sudo kubeadm init --pod-network-cidr=<CIDR_Range_for_IPAddress>

       

       

      1. Example: sudo kubeadm init --pod-network-cidr=10.244.0.0/16

   2. 

      mkdir -p $HOME/.kube

       

       

   3. 

      sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config

       

       

   4. 

      sudo chown $(id -u):$(id -g) $HOME/.kube/config

       

       

   5. 

      kubectl apply -fhttps://github.com/coreos/flannel/raw/master/Documentation/kube-flannel.yml

       

       

       

       

3. Execute the command below to list the nodes

   1. 

      kubectl get nodes

       

       

      

4. Execute the command below to generate a join command to execute on the worker nodes

   1. 

      kubeadm token create –print-join-command

       

       

      

5. On the Worker machines, execute the join command so that the machines join as workers in the Kubernetes cluster

   1. Example: kubeadm join 172.31.2.84:6443 --token fh9lqg.4ko0gz16owx1r8i6 --discovery-token-ca-cert-hash sha256:02fba06cea1124f3639e6aebbcf4f01464bd9dc22512fe50e208be8ed4d56582

      

      

6. On the master machine, execute the command below to list the nodes

   1. 

      kubectl get nodes

       

       

      

7. The Kubernetes cluster is up and running for workload deployment
