h2(#introduction). Introduction

To ease the installation of the various Arvados components, we have developed a "Saltstack":https://www.saltstack.com/ 's "arvados-formula":https://github.com/saltstack-formulas/arvados-formula which can help you get an Arvados cluster up and running.

Saltstack is a Python-based, open-source software for event-driven IT automation, remote task execution, and configuration management. It can be used in a master/minion setup or master-less.

This is a package-based installation method. The Salt scripts are available from the "tools/salt-install":https://github.com/arvados/arvados/tree/master/tools/salt-install directory in the Arvados git repository.

h2(#installmethod). Choose an installation method

The salt formulas can be used in different ways. Choose one of these three options to install Arvados:

* "Use Vagrant to install Arvados in a virtual machine":salt-vagrant.html
* "Arvados on a single host":salt-single-host.html
* "Arvados across multiple hosts":salt-multi-host.html
