kubernetes搭建dashboard-v1.10.1

一键部署脚本（或者可使用helm安装）：

wget https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml

kubectl apply -f kubernetes-dashboard.yaml

若连接不到镜像仓库，可提前下载好镜像，再执行脚本。

生成私钥和证书签名请求

openssl genrsa -des3 -passout pass：x -out dashboard.pass.key 2048

...

openssl rsa -passin pass：x -in dashboard.pass.key -out dashboard.key

＃编写RSA密钥

rm dashboard.pass.key

openssl req -new -key dashboard.key -out dashboard.csr

生成SSL证书

自签名SSL证书是从dashboard.key私钥和dashboard.csr文件生成的。

openssl x509 -req -sha256 -days 365-in dashboard.csr -signkey dashboard.key -out dashboard.crt
