Anycast Administration with SaltStack

Tue, 01 Jul 2014 15:04:33 -0500 » Anycast, Nerd Projects, Networking, IPv6, Programming, SaltStack, CLI, System Administration

I’ve been playing with SaltStack for a week or so now, and while I still haven’t even scratched the surface of what it is capable of yet, I am certainly saving a pile of time using it already. I am now using it to maintain web directories on my anycast nodes (which I was already doing through git, this is just further automated now).

My process was originally log into each system over ssh, then git pull each web directory. My process is now to run the following command on my salt master:

root@dev:~# salt -G roles:anycast cmd.run 'sh -c /home/theodore/gitupdate.sh'
h-186.wpg167lom.henchman21.net:

The script /home/theodore/gitupdate.sh exists on each anycast node. It goes into each directory and does a git update as the appropriate user (sudo -u user -H cmd).
