【Kubernetes】使用Kind部署k8s集群

安装Kind

参考：https://kind.sigs.k8s.io/docs/user/quick-start/#installation

Mac

建议使用Homebrew安装

brew install kind

Linux

# For AMD64 / x86_64
[ $(uname -m) = x86_64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.20.0/kind-linux-amd64
# For ARM64
[ $(uname -m) = aarch64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.20.0/kind-linux-arm64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind

创建集群

创建单节点集群

kind create cluster --name [cluster_name]

创建多节点集群

可以通过编写yaml文件实现，并使用指令部署

kind: Cluster         # 节点名称
apiVersion: kind.x-k8s.io/v1alpha4
nodes:                # 节点列表，需要几个节点写几个
- role: control-plane # master节点
- role: worker        # worker从节点
- role: worker

kind create cluster --config [yaml_file]

指定Kubernetes版本

image参考：https://github.com/kubernetes-sigs/kind/releases​

通过配置image参数实现

kind create cluster --config [yaml_file] --image [image]

如：kind create cluster --config kind.yaml --image kindest/node:v1.24.15@sha256:7db4f8bea3e14b82d12e044e25e34bd53754b7f2b0e9d56df21774e6f66a70ab

安装成功

出现以下提示则说明安装成功

~/: kind create cluster --config kind.yaml --image kindest/node:v1.24.15@sha256:7db4f8bea3e14b82d12e044e25e34bd53754b7f2b0e9d56df21774e6f66a70ab
Creating cluster "kind" ...

Set kubectl context to "kind-kind"
You can now use your cluster with:

kubectl cluster-info --context kind-kind

Not sure what to do next? 😅  Check out https://kind.sigs.k8s.io/docs/user/quick-start/

设置kubectl

根据[安装成功]的提示中的指令执行

kubectl cluster-info --context [cluster_name]-kind
