Create local kubernetes cluster using Kind

If you want to quickly spin up a local development environment of kubernets cluster, Kubernetes in docker aka Kind is the way to go

Kind runs the kubernetes inside a docker container as opposed to Minikube which used to run kubernetes inside a VM

Running Kind on linux requires to create a cluster configuration file cluster.yaml

Here is the sample configuration which would work for most of the cases:

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
  kubeadmConfigPatches:

  - |
     kind: InitConfiguration
     nodeRegistration:
     kubeletExtraArgs:
     node-labels: "ingress-ready=true"
     extraPortMappings:
     - containerPort: 80
       hostPort: 80
       protocol: TCP
     - containerPort: 443
       hostPort: 443
       protocol: TCP

kind create cluster --config=cluster.yaml

Upon creating the cluster, kubectl context is automatically set to point to kind cluster.

> kubectl cluster-info --context kind-kind
Kubernetes control plane is running at https://127.0.0.1:46251
CoreDNS is running at https://127.0.0.1:46251/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
