用Kind 安装k8s和k8s dashboard

2、 创建指定端口的集群

• 2.1 编辑配置文件 'kind-example-config.yaml'

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
networking:
# 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: "0.0.0.0"
# 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
nodes:
- role: control-plane
extraPortMappings:
- containerPort: 30001
  hostPort: 30001
  listenAddress: "0.0.0.0"
  protocol: tcp
- containerPort: 30002
  hostPort: 30002
  listenAddress: "0.0.0.0"
  protocol: tcp
- containerPort: 30003
  hostPort: 30003
  listenAddress: "0.0.0.0"
  protocol: tcp
- containerPort: 30004
  hostPort: 30004
  listenAddress: "0.0.0.0"
  protocol: tcp
- containerPort: 30005
  hostPort: 30005
  listenAddress: "0.0.0.0"
  protocol: tcp

• 2.2 根据配置文件创建集群

kind create cluster --config kind-example-config.yaml --name mycluster

3、安装k8s dashboard

• 3.1 下载配置文件

wget https://raw.githubusercontent.com/kubernetes/dashboard/v2.7.0/aio/deploy/recommended.yaml

• 3.2 编辑配置文件

• 3.3 根据配置文件执行安装

kubectl apply -f recommended.yaml

7、生成token 参考官方文档

8、登录态过期时间优化（默认15分钟）

需要说明的是，登录态过期时间不是token过期时间，按照第7步生成的token是永久有效的，网上都说成了token过期时间，有歧义！
修改流程参考 其中的43200 这个参数表示43200秒，也就是12小时；
修改完配置后，重启下才能生效
