Warning

Although this is a easiest way to build a cluster, but I wont recommend you to choose this. SInce there are many unsolved issue in here, check https://kind.sigs.k8s.io/docs/user/known-issues/

Preliminary

  • Kind binary has installed, if not check 🔗link

  • Hardware Requirements:

    1. At least 2 GB of RAM per machine (minimum 1 GB)
    2. 2 CPUs on the master node
    3. Full network connectivity among all machines (public or private network)

  • Operating System:

    1. Ubuntu 22.04/14.04, CentOS 7/8, or any other supported Linux distribution.

  • Network Requirements:

    1. Unique hostname, MAC address, and product_uuid for each node.
    2. Certain ports need to be open (e.g., 6443, 2379-2380, 10250, 10251, 10252, 10255, etc.)

Create your cluster

Creating a Kubernetes cluster is as simple as kind create cluster

kind create cluster --name test
Customize your cluster

If you need to configure your cluster, you can create kind-config.yaml

# 创建配置文件
cat <<EOF > kind-config.yaml
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
- role: worker
- role: worker
EOF

# 创建集群
kind create cluster --name my-cluster --config kind-config.yaml

# 等待容器启动
sleep 10

# 设置资源限制
docker update --memory="4g" --cpus="2" my-cluster-control-plane
docker update --memory="2g" --cpus="1" my-cluster-worker
docker update --memory="2g" --cpus="1" my-cluster-worker2

echo "✅集群创建完成，资源限制已应用"

Delete your cluster

kind delete cluster
