Mastodon

Mastodon is a federated microblogging engine. An alternative implementation of the GNU Social project. Based on ActivityStreams, Webfinger, PubsubHubbub and Salmon.

Current status of the project is early development. Documentation &co will be added later

Status

• GNU Social users can follow Mastodon users
• Mastodon users can follow GNU Social users
• Retweets, favourites, mentions, replies work in both directions
• Public pages for profiles and single statuses
• Sign up, login, forgotten passwords and changing password
• Mentions and URLs converted to links in statuses
• REST API, including home and mention timelines
• OAuth2 provider system for the API
• Upload header image for profile page

Missing:

• Media attachments (photos, videos)
• UI to post, reblog, favourite, follow and unfollow
• Deleting statuses, deletion propagation
• Streaming API

Configuration

• LOCAL_DOMAIN should be the domain/hostname of your instance. This is absolutely required as it is used for generating unique IDs for everything federation-related
• LOCAL_HTTPS set it to true if HTTPS works on your website. This is used to generate canonical URLs, which is also important when generating and parsing federation-related IDs
• HUB_URL should be the URL of the PubsubHubbub service that your instance is going to use. By default it is the open service of Superfeedr

Requirements

• PostgreSQL
• Redis

Running with Docker and Docker-Compose

The project now includes a Dockerfile and a docker-compose.yml. You need to turn .env.production sample into .env.production with all the variables set before you can:

docker-compose build

And finally

docker-compose up

As usual, the first thing you would need to do would be to run migrations:

docker-compose run web rake db:migrate
