salt-master
===========

![](https://badge.imagelayers.io/vimagick/salt-master:latest.svg)

Salt is a new approach to infrastructure management. Easy enough to get running
in minutes, scalable enough to manage tens of thousands of servers, and fast
enough to communicate with them in seconds.

Salt delivers a dynamic communication bus for infrastructures that can be used
for orchestration, remote execution, configuration management and much more.

This image contains `salt-master`/`salt-ssh` and other power tools:

- curl
- httpie
- ipython
- jq
- vim-tiny
