cgroupDriver: cgroupfs


kubeadm init --config kubeadm-config.yaml


Switch to tekton normal user and execute below commands

  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://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')"


kubectl taint node footslog1.fyre.ibm.com node-role.kubernetes.io/master:NoSchedule-

kubectl run nginx-demo --image=nginx --port=80
 
kubectl expose pod nginx-demo --port=80 --type=NodePort
