• こんな感じでsidekiqを複数立ち上げてやってます。

  sidekiq1:
    restart: always
    build: .
    image: gargron/mastodon
    env_file: .env.production
    command: bundle exec sidekiq -c 5 -q default
    depends_on:
      - db
      - redis
    volumes:
      - ./public/system:/mastodon/public/system

  sidekiq2:
    restart: always
    build: .
    image: gargron/mastodon
    env_file: .env.production
    command: bundle exec sidekiq -c 5 -q mailers
    depends_on:
      - db
      - redis
    volumes:
      - ./public/system:/mastodon/public/system

  sidekiq3:
    restart: always
    build: .
    image: gargron/mastodon
    env_file: .env.production
    command: bundle exec sidekiq -c 5 -q pull
    depends_on:
      - db
      - redis
    volumes:
      - ./public/system:/mastodon/public/system

  sidekiq4:
    restart: always
    build: .
    image: gargron/mastodon
    env_file: .env.production
    command: bundle exec sidekiq -c 5 -q push
    depends_on:
      - db
      - redis
    volumes:
      - ./public/system:/mastodon/public/system
