Upgrade notes

Because this is a backport, it is not available with git pull. Use git fetch && git checkout v2.8.3

As always, make sure you have backups of the database before performing any upgrades. If you are using docker-compose, this is how a backup command might look: docker exec mastodon_db_1 pg_dump -Fc -U postgres postgres > name_of_the_backup.dump

Both Docker and non-Docker:

  1. Run database migrations:
    • Non-Docker: RAILS_ENV=production bundle exec rails db:migrate
    • Docker: docker-compose run --rm web rails db:migrate
  2. Precompile the assets:
    • Non-Docker: RAILS_ENV=production bundle exec rails assets:precompile
    • Docker: The assets are already precompiled during the build step
  3. Restart all Mastodon processes
Assets 2
You can’t perform that action at this time.
