Thinking about moving my instance to docker. In your experience, are there any downsides besides the migration itself? #mastodon #mastoadmin #docker #selfhost #selfhosted #selfhosting #homelab

    @chad I can't speak directly to running a Mastodon as a container but I use Docker extensively in my homelab for everything else. Generally speaking, there is a small amount of overhead that's added on vs running it natively, but its negligible. Updates are way easier since you're just updating the Docker image. Backups are easier since you only need to backup whatever files you you mount to the container (plus the database you tie to it). 1/2

    @chad There are some notable differences. A few of the integrations (Whisper, for example) can't be installed directly from the web interface in a Docker container. You have to install some containers alongside HA. Overall I've never run into a serious roadblock, but just be aware you might need to spend more time researching how to set up some things.

    @chad it'll be the best move you'll make. 0 downtime upgrades (if you take appropriate steps) and no dependency hell. The downside is if you want to alter the source code at all, rebuilding the docker image is a bit of a pain.

    @chad I can't think of any beyond needing to wait for the newer docker images to be generated when a new release is made, but that's generally really quick and upgrading to newer versions is a breeze. Highly recommended.
