- All kubernetes files are present in kube folder
- Run kubectl apply -f kube 
- This creates all the pods required
- Check pods status using kubectl get pods

Cluster

---

• In master node

  • kubeadm init --apiserver-advertise-address $(hostname -i)
  • mkdir -p $HOME/.kube
  • sudo cp /etc/kubernetes/admin.conf $HOME/
  • sudo chown $(id -u):$(id -g) $HOME/admin.conf
  • export KUBECONFIG=$HOME/admin.conf
  • echo "export KUBECONFIG=$HOME/admin.conf" | tee -a ~/.bashrc
  • Apply networking using kubectl apply -n kube-system -f
    "https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"
  • Check master node status using kubectl get pods -n kube-system

• Worker nodes

  • Connect to master nodes using master node token
  • mkdir -p $HOME/.kube
  • sudo cp /etc/kubernetes/admin.conf $HOME/
  • sudo chown $(id -u):$(id -g) $HOME/admin.conf
  • export KUBECONFIG=$HOME/admin.conf
