# KLS

## Description

`kls` is a cli tool based on `kubectl` for managing kubernetes cluster resources.
Inspired by `lf` and `ranger` file managers, written in python.

It is lightweight (~400 lines of code) and easy to customize.
Supports keyboard navigation and mouse navigation could be enabled (set MOUSE_ENABLED=True in a line #69).

## Key bindings

### Other:
