Create a K8S cluster with kind

cat  <<EOF >kind-config.yaml 
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
- role: worker
- role: worker
networking:
  disableDefaultCNI: true
  podSubnet: 192.168.0.0/16
  serviceSubnet: "10.11.0.0/16"
EOF

kind create cluster --config=kind-config.yaml
kubectl cluster-info --context kind-kind
kubectl get no

Check if all pods are running or pending

kubectl get po -A

If you experience crashes, it is because of the bug in kind. Contact your instructor.

Install Calico CNI

kubectl apply -f  https://raw.githubusercontent.com/projectcalico/calico/v3.26.1/manifests/calico.yaml

Verify cluster

watch kubectl get po -n calico-system

When all pods are running … the nodes should be ready.

kubectl get no -o wide
