Source Code
Our goal is to provide the best possible Mastodon experience for our members.
One way to deliver on that is by delivering the most up-to-date Mastodon code.
We "run off main", which means using the latest commits to the main branch of the Mastodon codebase found on the project's official GitHub repository.
We take a clean copy of the latest Mastodon code and then apply a limited set of modifications with a custom script. We then build the modified code inside a Docker container, publish it to GitHub Container Registry, for consumption by our Kubernetes cluster.
Our server-specific customizations include:
- Customizing the Mastodon logo colors (if needed) for events like Pride Month, etc.
- Raising the post character count limit from 500 to 640 (vmstan/mastodon #36)
- Adding Docs link to the sidebar (vmstan/mastodon #53)
- Raising image attachment maximums from 8MP to 48MP (vmstan/mastodon #54)
- Raising the poll option limit from 4 to 6 (vmstan/mastodon #55)
- Fixing YouTube link previews by modifying the User-Agent for youtube.com (vmstan/mastodon #57)
Individual container builds may include additional changes which are being tested on vmst.io, and may be sourced from PR's in the official project repository or in the vmst.io development fork.
Container Availability

Our customized container image is available from both Docker and GitHub container registries. This is suitable for the web/Puma and Sidekiq services.
