Welcome to kubed-sh
, the Kubernetes distributed shell for the casual cluster user. In a nutshell, kubed-sh
lets you execute a program in a Kubernetes cluster without having to create a container image or learn new concepts.
For example, let's say you have a Node.js script called test.js
and you want to launch it as a containerized app in your Kubernetes cluster,
here's what you'd need to do in kubed-sh
:
1 2 3 4 | [kind::default]$ node test.js & [kind::default]$ ps DPID SOURCE URL kubed-sh-1517679562543558000 test.js test |
Does this look familiar to what you do in your "local" shell? That's the point of kubed-sh
: it allows you to use Kubernetes without needing to learn anything new.

In addition to launching (Linux ELF) binaries directly, the following interpreted environments are supported:
- When you enter
node script.js
,kubed-sh
launches a Node.js (default v12) container, copies the script into it and starts it. - When you enter
python script.py
,kubed-sh
launches a Python (default v3.6) container, copies the script into it and starts it. - When you enter
ruby script.rb
,kubed-sh
launches a Ruby (default v2.5) container, copies the script into it and starts it.
Tip
Since kubed-sh
is a proper shell environment. This means you can expect
features such as auto-complete of built-in commands, history operations (CTRL+R
), or clearing the screen (CTRL+L
) to work as per usual.
