Docker Desktop 启动 K8s
1、Docker Desktop 开启 K8s，总是报错
2、改为手动下载 K8s 相关的镜像（参考这里）
3、重新启动，右下角会显示报错信息
"{\"message\":\"starting kubernetes: initializing PKI: initializing PKI: error creating PKI assets: failed to write or validate certificate \\\"etcd-server\\\": certificate etcd/server is not signed by corresponding CA\"}\n{\"message\":\"starting kubernetes: initializing PKI: initializing PKI: error creating PKI assets: failed to write or validate certificate \\\"etcd-server\\\": certificate etcd/server is not signed by corresponding CA\"}\n{\"message\":\"starting kubernetes: initializing PKI: initializing PKI: error creating PKI assets: failed to write or validate certificate \\\"etcd-server\\\": certificate etcd/server is not signed by corresponding CA\"}\n"
之前我安装过 K8s，证书过期了，参考官网 issue 我把
/Users/{user_name}/Library/Containers/com.docker.docker/pki
修改为
/Users/{user_name}/Library/Containers/com.docker.docker/_pki
重启 Docker Desktop 成功启动
kubectl 版本较老，参照文档更新下
继续参照这个文档安装 dashboard
