Kind本地部署kubernetes环境

kind简介：

kind是一种在本地用docker启动kubernetes集群的工具，主要是用来测试kubernetes本身的，但有也用于本地开发和CI。

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

mac上安装使用如下命令
brew install kind

通常使用配置文件来创建集群，配置文件如下所示：

cluster.yaml
kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
name: kind-cluster # 指定集群名称
#开启指定featureGates
#featureGates:
#  "CSIMigration": true
networking:
  # apiserver配置 根据实际需求改，例如需要外部客户端访问，默认是127.0.0.1
  # WARNING: It is _strongly_ recommended that you keep this the default
  # (127.0.0.1) for security reasons. However it is possible to change this.
  apiServerAddress: "192.168.10.3"
  # By default the API server listens on a random open port.
  # You may choose a specific port but probably don't need to in most cases.
  # Using a random port makes it easier to spin up multiple clusters.
  apiServerPort: 6443
  
  # 设置pod ip段
  podSubnet: "10.233.0.0/16"
  
  # 设置service ip段
  serviceSubnet: "10.96.0.0/12"
  
  # 关闭默认的cni插件kindnetd， 使用第三方插件
  # the default CNI will not be installed
  disableDefaultCNI: false
  
  # kube-proxy mode设置，默认是iptables
  kubeProxyMode: "ipvs"
  
  
  
nodes:
- role: control-plane
  image: kindest/node:v1.21.14 # 指定版本号
  # 端口映射，
  extraPortMappings:
  - containerPort: 30950 # 容器端口号
    hostPort: 10950 # 宿主机端口号
- role: worker
  image: kindest/node:v1.21.14
- role: worker
  image: kindest/node:v1.21.14
- role: worker
  image: kindest/node:v1.21.14

创建集群

kind create cluster --config=./cluster.yaml

注意，如果kind所在机器跟kubectl机器不是同一台，需要将apiServerAddress改为kind所在机器的地址，然后使用kubecm add config文件即可。
