当使用wget下载k8s-dashboard.yaml的时候,提示:

Unable to establish SSL connection.

解决:

# wget https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml --no-check-certificate

wget后跟的url为https,对应端口443,https为加密传输的协议

所以加上参数 --no-check-certificate 一起使用,--no-check-certificate 作用是在不检查安全证书,以不安全的方式连接指定url的作用
