Mastodon Update/Upgrade script

new_masto_release.sh

#!/bin/bash
# This script works on the theory that you use a tagged image in your docker-compose.yaml
# i.e. "image: tootsuite/mastodon:v4.0.2"

# Make a database backup
docker exec mastodon_db_1 pg_dump -Fc -U postgres postgres > pre-4-0-2.dump

# replace the old tag with the new tag
sed -s 's/v4.0.1/v4.0.2/g' -iv4.0.1 docker-compose.yml

# Pull the new images
docker-compose pull

# run the upgrade/migrations
docker-compose run --rm -e SKIP_POST_DEPLOYMENT_MIGRATIONS=true web rails db:migrate
docker-compose down
docker-compose run --rm web bin/tootctl cache clear
docker-compose run --rm web rails db:migrate
docker-compose up -d

# clean up old, unused images
docker system prune -a
