Local Mastodon with `docker-compose`

README.md

!!! THIS NO LONGER WORKS, FUCK'S SAKE MASTODON !!!

Clone, patch, build containers

git clone https://github.com/mastodon/mastodon
cd mastodon
{ curl https://gist.githubusercontent.com/pikesley/f573e283d7c3724f7cb202e73e0f49ee/raw/4d25875d725ecc280ff671a3e5317308568d8d1c/hack.patch ; echo ; } | git apply -v --index # apply my patch
touch .env.production
docker compose build

• the patch allows localhost to hit the server, and disables force_ssl

Setup and migrations

docker-compose run --rm -e DISABLE_DATABASE_ENVIRONMENT_CHECK=1 web bundle exec rake mastodon:setup

• THIS SPITS OUT A BUNCH OF CONFIG PARTWAY-THROUGH AND TELLS YOU TO WRITE IT TO .env.production, IT DOESN'T SAVE IT FOR YOU LIKE I ASSUMED IT HAD
• it fails at "Creating admin user" with some complaints about not being able to connect to Redis on localhost ¯\_(ツ)_/¯
• HOWEVER if you run it again, it works
• it's all so, so ugly

Run it

docker compose up

Now you should be able to hit it at http://locahost:3000
