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/arvados/arvados-formula.git 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 to install and configure Arvados using this formula are available at the "tools/salt-install":https://github.com/arvados/arvados/tree/master/tools/salt-install directory in the Arvados git repository.

h2(#saltstack). Install Saltstack

If you already have a Saltstack environment or you plan to use the @provision.sh@ script we provide, you can skip this section.

The simplest way to get Salt up and running on a node is to use the bootstrap script they provide:

<notextile>
<pre><code>curl -L https://bootstrap.saltstack.com -o /tmp/bootstrap_salt.sh
sudo sh /tmp/bootstrap_salt.sh -XUdfP -x python3
</code></pre>
</notextile>

For more information check "Saltstack's documentation":https://docs.saltstack.com/en/latest/topics/installation/index.html

h2(#installconfiguration). Choose an Arvados installation configuration

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

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