There are some nice things about Docker, like being able to run Rails 1.2.3 on Ruby 1.8 so I can load up this ancient ass Rails app. It's version 2 of the old https://penguindreams.org .. needed to get it running to pull a screenshot for an upcoming post on old versions of my website. Bask in its 2008 glory!
I had to hack a bunch of gems to get it to actually work, but now I can export the container and save it off in case I never want to run it again for whatever god forsaken reason.
