Centos:7 with openssh installed.
Start the sshd server in Kubernetes. The server can be used as jumpbox to access Kubernetes inernal network.
TLDR;
make all
kubectl describe service sshd-jumpserver
ssh -i sshkeys/idrsa root@${LoadBalancer Ingress address}
generate the id_rsa key or copy your own key to sshkeys folder
make newkey
make gensecret
make addsshkey
make deploy
kubectl describe service sshd-jumpserver
Name: sshd-jumpserver
