I created a 3 node cluster in GKE using the below command

gcloud container clusters create kubia --num-nodes 3 --machine-type=f1-micro

The status of all the three nodes is NotReady. When I inspected the node using the kubectl describe <node>, I get the following output:

λ kubectl describe node gke-kubia-default-pool-c324a5d8-2m14

Where I am going wrong? I am able to create pods using the kubectl run kubia-3 --image=luksa/kubia --port=8080 --generator=run/v1 command.
