salt, or [http://www.saltstack.com/ saltstack], is a provisioning system like puppet or chef. It's the provisions system PS:One Systems Group uses to manage and maintain the servers.
== Adding a new box ==
== Adding a new box ==
sudo salt-key -a foobox
sudo salt-key -a foobox
sudo salt 'foobox' state.highstate
sudo salt 'foobox' state.highstate
== Changeing salt config ==
* Make your changes in /srv/salt/
=== Test your changes ===
Test your changes. Testing against a single box is wiser than testing against the entire network
sudo salt 'sally.ad.pumpingstationone.org' state.highstate test=True
If you are satisfied, run the command for real
sudo salt 'sally.ad.pumpingstationone.org' state.highstate
reboot the box and make sure it still comes back up and works correctly.
=== Deploying changes ===
sudo salt --state-output=mixed '*' state.highstate test=True
sudo salt '*' state.highstate
== Upgrading Everything ==
test the upgrade against a single box
<syntaxHighlight lang=bash>
sudo salt 'sally.ad.pumpingstationone.org' pkg.upgrade
sudo salt 'sally.ad.pumpingstationone.org' cmd.run 'reboot'
</syntaxHighlight>
After rebooting the test box, log back in and make sure everything appears to work correctly.
Once you are satisfied you are not going to have a long night repairing the network, deploy upgrades everywhere.
<syntaxHighlight lang=bash>
sudo salt '*' pkg.upgrade
</syntaxHighlight>
== Adding someone's SSH key to root access ==
1. Get an SSH key. Here are some simple instructions:

*[https://www.ssh.com/ssh/putty/windows/puttygen Windows]
It would be nice if this was better documented.
