# KLS
## Description
`kls` is a cli tool for managing kubernetes cluster resources. Inspired by `lf` and `ranger` file managers. Written on python curses.
## Key bindings
`kls` is a cli tool for managing kubernetes cluster resources. Inspired by `lf` and `ranger` file managers.
It is lightweight and easy to customize
## Key bindings for kubectl
- `1` - get yaml of resource
- `2` - describe resource
- `3` - edit resource
- `4` - logs of pod
- `a-zA-Z` - filter menu
- `Esc` - exit filter mode or exit `kls`
You can customize these bindings or add extra bindings in `KEY_BINDINGS` variable of `kls` (in a row #4).
Also you can add additional columns for different api resources in `EXTRA_COLUMNS` variable (in a row #11).
