For reasons, I needed to spin up a very old WordPress site using Docker today. I’m writing this blog post mostly just to jot down the compose file so I have it handy in the future.
Digging through the oldest tags for the wordpress image on DockerHub it looked like 4.1 was the oldest version available, so I went with it. For the database, I went with the last version of MySQL version 5.

I’ve got a whole list of improvements I want to make to this site coming off of Reclaim Open.
This blog is a static site made with hugo and of course hosted on Reclaim Hosting. If you are curious about how it works, I’ve done a stream and accompanying blog post about it:

Here are some quick notes from helping Jim upgrade his bava.tv Peertube instance from PostgreSQL 10 to PostgreSQL 13. bava.tv uses Docker so actually changing Postgres versions is dead simple (basically just edit a number in the docker-compose.yml file and restart the containers) but we found out pretty quickly that you can’t just change the version of Postgres, and expect the database to still work.
First I cloned the environment and added Adminer to the docker-compose.
