• Deployable with Docker (Docker compose for everything: dev, test and deployment)
• Focused on testing
  • The core ActivityPub code/tests are in Little Boxes
  • Tested against the official ActivityPub test suite (report submitted)
  • CI runs "federation" tests against two instances
  • Manually tested against Mastodon
  • Project is running an up-to-date instance

ActivityPub

microblog.pub implements an ActivityPub server, it implements both the client to server API and the federated server to server API.

Compatible with Mastodon (which is not following the spec closely), but will drop OStatus messages.

Activities are verified using HTTP Signatures or by fetching the content on the remote server directly.

Running your instance

Installation

$ git clone https://github.com/tsileo/microblog.pub
$ cd microblog.pub
$ pip install -r requirements.txt
$ make css
$ cp -r config/me.sample.yml config/me.yml

Configuration

$ make password
Password: <enter a password; nothing will show on screen>
$2b$12$iW497g...

Edit config/me.yml to add the above-generated password, like so:

username: 'username'
name: 'Your Name'
icon_url: 'https://you-avatar-url'
domain: 'your-domain.tld'
summary: 'your summary'
https: true
pass: $2b$12$iW497g...

Deployment

Note: some of the docker yml files use version 3 of docker-compose.

$ docker-compose up -d

Development

The most convenient way to hack on microblog.pub is to run the server locally, and run

# One-time setup
$ pip install -r requirements.txt
# Start the Celery worker, RabbitMQ and MongoDB
$ docker-compose -f docker-compose-dev.yml up -d
# Run the server locally
$ FLASK_DEBUG=1 MICROBLOGPUB_DEBUG=1 FLASK_APP=app.py flask run -p 5005 --with-threads
