What is Kind ?

With "kind," you can easily create a Kubernetes cluster using Docker containers as nodes. This is great for development, testing, and CI/CD tasks. It allows you to quickly deploy Kubernetes clusters on your local machine without needing any special hardware or cloud services.

Prerequisites

Docker installed on your local machine.

Installation of Kind

Follow this documentation to install Kind.

Single Node Cluster

• To create a Kubernetes cluster using Kind, you can use the following command

    kind create cluster
  

  Output

• To delete a Kubernetes cluster using Kind, you can use the following command.

    kind delete cluster
  

  Output

Multi Node Cluster

• Create a Cluster Configuration File: Create a YAML configuration file [kind-config.yaml] specifying the desired cluster setup, detailing the node count and their respective roles (control-plane or worker). Below is a sample configuration file:

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

  This configuration creates a cluster with one control-plane node and one worker node.

• Create the Cluster: Run the following command to create the cluster using Kind and the configuration file:

    kind create cluster --config kind-config.yaml --name my-multi-node-cluster
  

  Output

• Verify the Cluster: After the cluster creation process is finished, you can confirm that the cluster is running correctly by executing the following command:

    kubectl get nodes
  

  Output

• Delete the Cluster: To delete a Kubernetes cluster using Kind, you can use the following command.

    kind delete cluster --name my-multi-node-cluster
