SSH成Kubernetes群集上亚马逊

Question

运行的创建一个2节点Kubernetes集群：

KUBERNETES_PROVIDER=aws NUM_NODES=2 kube-up.sh 

这显示了输出为：

Found 2 node(s). 
NAME           STATUS AGE 
ip-172-20-0-226.us-west-2.compute.internal Ready  57s 
ip-172-20-0-227.us-west-2.compute.internal Ready  55s 
Validate output:

Cluster validation succeeded 
Done, listing cluster services:

我可以看到在EC2控制台实例。我如何进入主节点？

Answer 1

“创建一个名为kubernetes的AWS SSH密钥。这里的指纹是OpenSSH密钥指纹，因此多个用户可以使用不同的密钥运行脚本，并且密钥不会相互碰撞（几乎可以肯定）。现有的密钥，如果一个在AWS_SSH_KEY发现，否则会造成一个有（随着Ubuntu默认的图像，如果你有SSH方式：用户是Ubuntu和用户可以须藤”

你应在ssh config本地查看ssh密钥指纹或设置ENV并重新创建。

Answer 2

这里是为我工作的准确命令：

ssh -i ~/.ssh/kube_aws_rsa admin@<masterip> 

kube_aws_rsa是生成的默认密钥，AWS_SSH_KEY环境变量，否则控制。对于AWS，它在文件cluster/aws/config-default.sh中指定。
