Upgrading Mastodon through multiple updates

Some very specific instructions I had to write down in order to upgrade my Mastodon instances from v4.2.17 to v4.4.5

4.2.17 -> 4.2.26

• run ./backup.sh
• run docker compose down
• edit compose.yaml, updating the tag on:
  • web
  • streaming
  • sidekiq
• run docker compose pull
• run db migration: docker compose run --rm web rails db:migrate
• run docker compose up -d
• restart nginx

4.2.26 -> 4.3.13

• run ./backup.sh
• run docker compose down
• edit compose.yaml, updating the tag on:
  • web
  • streaming
  • sidekiq
• edit compose.yaml, change streaming to use image ghcr.io/mastodon/mastodon-streaming
• run docker compose pull
• run db migration: docker compose run --rm -e SKIP_POST_DEPLOYMENT_MIGRATIONS=true web rails db:migrate
• set encryption keys: docker compose run --rm web rails db:encryption:init
• copy the encryption keys to .env.production
• run db migration again: docker compose run --rm web rails db:migrate
• edit main nginx config:

 ##
 # Connection header for WebSocket reverse proxy
 ##
 map $http_upgrade $connection_upgrade {
  default upgrade;
  '' close;
 }

• edit site nginx config, under location ^~ /api/v1/streaming:

  proxy_set_header Proxy "";
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection $connection_upgrade;
  add_header Strict-Transport-Security "max-age=63072000; includeSubDomains";

• run docker compose up -d
• restart nginx

4.3.13 -> 4.4.5

• run ./backup.sh
• run docker compose down
• edit compose.yaml, updating the tag on:
  • web
  • streaming
  • sidekiq
• run docker compose pull
• run db migration: docker compose run --rm -e SKIP_POST_DEPLOYMENT_MIGRATIONS=true web rails db:migrate
• If needed, remove the REDIS_NAMESPACE variable (more info here)
  • download rename.rb into redis folder
  • run redis migration: docker compose run --rm redis rails runner /data/rename.rb
  • remove REDIS_NAMESPACE from .env.production
• run db migration again: docker compose run --rm web rails db:migrate
• rebuild feeds: docker compose run --rm web bundle exe tootctl feeds build
• run docker compose up -d
• restart nginx
