Running Mastodon with Nomad

This repository is designed to be read with my blog post, and you should be familiar with the first-party setup guide too.

It includes Nomad task definitions that I use to run my own Mastodon instance, as well as a couple of helpful scripts. They're tuned to run on a single t4g.medium server on AWS.

It's supposed to be for inspiration, rather than a step-by-step guide. You won't be able to run it out of the box using this repository, but I hope it's useful as a reference to get you started.

If you know of a better way to do something, or want to offer other improvements, please send me a message on Mastodon @[email protected] before opening a PR.

For interest, it's actually a redacted copy of the cluster folder, from a repository I use to manage the infrastructure for bunny.cloud. Not included are the terraform and ansible definitions for all the underlying infrastructure.

Components

The Nomad task definitions include:

• A front proxy (nginx)
• Web server (Mastodon - Ruby on Rails)
• A message processor (Mastodon - Sidekiq)
• A streaming server (Mastodon - Node)
• A SQL migrations task (ran before every deploy)
• A periodic cleanup task (to remove old media)

Scripts

• install_dependencies.sh installs local dependencies to run scripts
• deploy_cluster.sh uses the Nomad CLI to deploy all the tasks
• ./tootctl.sh runs a given tootctl command in a running sidekiq allocation
