Kind Setup

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

Verify Docker available
```
docker info
```
If this fails, STOP. DinD is not available.

Delete existing cluster

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

Create cluster
```
kind create cluster --name ark-cluster
```

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

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.
