salt, or 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
When you install salt-minion on a client box, you will need to
sudo salt-key -L sudo salt-key -a foobox 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.
sudo salt --state-output=mixed '*' state.highstate test=True
sudo salt '*' state.highstate
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>
