SSH 进入在 Amazon 上运行的 Kubernetes 集群

Question

创建了一个 2 节点 Kubernetes 集群:

KUBERNETES_PROVIDER=aws NUM_NODES=2 kube-up.sh

这将输出显示为:

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:
NAME                 STATUS    MESSAGE              ERROR
controller-manager   Healthy   ok

etcd-0               Healthy   {"health": "true"}   
etcd-1               Healthy   {"health": "true"}   
Cluster validation succeeded
Done, listing cluster services:

我可以在 EC2 控制台中看到实例。如何通过 ssh 进入主节点？

Answer 1

这是对我有用的确切命令:

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

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

可以使用 kubectl.sh config view 找到有关集群的更多详细信息。 .
