name: Kind Setup description: Create a Kind cluster in Docker-in-Docker environment

Kind Setup

Create a Kind Kubernetes cluster inside a DinD (Docker-in-Docker) container.

When to use

• Setting up Kubernetes for testing
• Need a Kind cluster inside this container

Steps

1. Verify Docker available

   docker info
   

   If this fails, STOP. DinD is not available.

2. Delete existing cluster

   kind delete cluster --name ark-cluster 2>/dev/null || true
   

3. Create cluster

   kind create cluster --name ark-cluster
   

4. Configure kubeconfig with container IP

   CONTROL_PLANE_IP=$(docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' ark-cluster-control-plane)
   kind get kubeconfig --name ark-cluster --internal | sed "s/ark-cluster-control-plane/$CONTROL_PLANE_IP/g" > ~/.kube/config
   

5. Verify connection

   kubectl cluster-info
   

Why the IP replacement?

This container connects to Kind via Docker networking. The default 127.0.0.1 or hostname won't work. Using the container's actual IP ensures connectivity.
