docker exec mastodon_db_1 pg_dump -Fc -U postgres postgres > mastodon-db-`date +%Y-%m-%d`.dump
Redis
Copy the rdb with cp /srv/data/mastodon/redis/dump.rdb dump.rdb.`date +%Y-%m-%d`

Build image

$ cd /opt/mastodon
$ git fetch
$ git rebase origin/master # or a version tag
$ docker-compose build

Deploy new containers

$ docker-compose run --rm web rails db:migrate
$ docker-compose up -d

Sometimes, the database migration is time consuming. In such case:

$ docker-compose run --rm -e SKIP_POST_DEPLOYMENT_MIGRATIONS=true web rails db:migrate
$ docker-compose up -d
$ docker-compose run --rm web rails db:migrate
