Kubectl get pods -A -n kube-system

Here incase flannel installed go for  Calico

Calico already installed go for flannel

Kubectl apply -f  <link>

Kubectl  get pods -n kube-flannel

Its shows error

Kubectl logs   kube-flannel-ds-5mh5s  -n kube-flannel

Does not cotaine 192.168.1.0/16  network   so we need to add the network in configmap file

Kubectl get cm  -n kube-flannel

We need to edit the configmap

Kubectl edit cm kube-flannel-cfg  -n kube-flannel

Change here to 192.168.0.0/16  you can give 192.168.1.0/16 also

Save the file

Kubectl get pods -n kube-flannel

Now it showing CreshLoopBackOff

Just remove the pods

Now check the pods now its sucessfully running the pods

Kubectl get pods -n kube-flannel

For testing create two test pods
