Is there a wiki page for mediawiki-tools-ansible-wikifarm?

Sadly, no, but the instructions for using it are pretty well documented in the README file: https://phabricator.wikimedia.org/diffusion/1881/browse/master/README. The debian port that I use on Wikimedia Cloud Services is at https://github.com/cicalese/debian_wikifarm. There are a couple of things I need to do manually on Wikimedia Cloud services after running the scripts; I haven't had the time to fix the scripts. In particular, the internal server hostname x.eqiad.wmflabs needs to be changed in mediawiki/WikiFarm/Server.php to x.wmflabs.org. And, the ini file for luastandalone is set for apache2 automatically but not cli. I stopped working on evolving these scripts since the NASA meza work handles a few things (e.g. load balancing) that these do not. And, since I no longer managing customer-facing wikifarms as my day job, I haven't had the time to continue to invest effort in them except for my own convenience. However, a lot of work went into them that I'd love to see benefit others.
