httpbin, whoami, qotm (quote of the moment) 服务特别适合用来作为测试

kubectl create namespace httpbin
kubectl create deploy httpbin --image=citizenstig/httpbin --port=8000 -n httpbin
kubectl expose deployment httpbin --name=httpbin -n httpbin --port=80 --target-port=8000

kubectl create ns whoami
kubectl create deploy whoami --image=containous/whoami --port=80 -n whoami --replicas=3
kubectl expose deployment whoami --name=whoami -n whoami --port=80 --target-port=80

Setup keyless login

1. On local make an RSA key if you haven't already (ssh-keygen)
2. Copy that key into .ssh/authorized_keys on the first (i.e. bastion) server (ssh-copy-id [email protected]) 2b. Test that you can ssh [email protected] and connect without password
3. ssh to bastion.server and create an RSA key on bastion.server if you haven't already (ssh-keygen)
4. ssh-copy-id to the server you want to access (what I am calling real.server) 4b. test that you can ssh from bastion.server to real.server without entering a password

To copy from server to local

rsync -e "ssh [email protected] ssh" [email protected]:/path/to/file /path/to/local/dest
