As part of T120345: Set up mass visual diff testing with a custom install of mediawiki, I have created two labs VMs mw-base.wikitextexp and mw-expt.wikitextexp. On each VM, I've configured a multiwiki mediawiki-vagrant setup. Right now, they each have 41 wikis. So, I need 41 proxies set up for each VM.
One solution is to go horizon.wikimedia.org and fill out a form for each of the 82 proxies. That would work. But, if I add / remove wikis or if an instance goes down and I need to do this again, it would be somewhat painful.
So, filing this ticket for labs folks to figure out the best maintainable solution that might also arise in other contexts for other projects.
