kubed-sh

"The Kubernetes distributed shell for the casual cluster user.  In a nutshell, kubed-sh (pronunciation) lets you execute a program in a Kubernetes cluster without having to create a container image or learn new commands.

In addition to launching (Linux ELF) binaries directly, the following interpreted environments are currently supported:

• When you enter node script.js, a Node.js (default version: 9.4) environment is provided and script.js is executed.
• When you enter python script.py, a Python (default version: 3.6) environment is provided and the script.py is executed.
• When you enter ruby script.rb, a Ruby (default version: 2.5) environment is provided and the script.rb is executed.

Note that kubed-sh is a proper shell environment, that is, you can expect features such as auto-complete, history operations, or CTRL+L clearing the screen to work as per usual."
