kind - setting up your local kubernetes cluster on windows

kind uses docker to setup a kubernetes cluster locally. Each node is a running container in docker. 

To get started started, go to your default directory and then run the following command 

curl.exe -Lo kind-windows-amd64.exe https://kind.sigs.k8s.io/dl/v0.24.0/kind-windows-amd64

Move-Item .\kind-windows-amd64.exe kind.exe

To create a cluster, run the following 

kind create cluster

After that you should see that we have a kubernetes cluster called kind-kind.

Configuring worker node for kind cluster

Let's say you want to have 2 nodes running in your cluster, you can proceed to do that with a configuration file as shown below:- 

kind: Cluster

apiVersion: kind.x-k8s.io/v1alpha4

nodes:

  - role: control-plane

  - role: worker

  - role: worker  # This is the additional node

## kind create cluster --config kind-config.yaml  

Then simply run it by 

kind create cluster --config .\kind-config.yml

As you can see in the diagram below,  there's 3 containers - one kind control pane and 2 worker node. All of these running as docker containers.

To configure a highly available control plane, we can use the following yaml 

kind: Cluster

apiVersion: kind.x-k8s.io/v1alpha4

nodes:

- role: control-plane

- role: control-plane

- role: control-plane

- role: worker

- role: worker

- role: worker
