Finally updated my self-hosted #Mastodon server to the latest v4.1.4 this morning. Since I run it in a #Docker Swarm (for now), it took me a little bit to figure out how to run the Rails DB migrations.
I wound up exec’ing into the "web” service in the Docker stack and running the command directly inside the container. That's obviously not something you usually do with ephemeral containers, but in this case it was making changes to the associated databases, so it worked fine.
