It is a fork of yokawasa/kubectl-plugin-ssh-jump. I had some ideas how can I improve this plugin, thus the fork. Currently, there is only a manual installation, but maybe I will add this plugin to krew. I do not know yet.
A kubectl plugin to SSH into any machine within a network using a SSH jump host Pod.
A jump host Pod is an intermediary Pod through which a connection can be made to any machine within a network.
Here is an scenario where you want to connect to a machine, but you have to go through a jump host Pod, because of firewalling, access privileges. etc. There is a number of valid reasons why the jump hosts are needed.
This plugin needs the following programs:
- ssh (>=8.5)
- ssh-agent
- ssh-keygen
# Get source
$ git clone https://github.com/tomislater/kubectl-plugin-ssh-jump.git
$ cd kubectl-plugin-ssh-jump
$ chmod +x kubectl-ssh-jump
# Add kubeclt-ssh-jump to the install path.
$ sudo cp -p kubectl-ssh-jump /usr/local/bin/kubectl-ssh_jumpThen, run:
