如何修复docker-compose.yml？ -预期<块结束&gt ;，但发现'<块映射开始>'

似乎我的yml文件中存在缩进问题。我在这里阅读了其他一些问题，并尝试了各种缩进方案。我仍然无法正常工作。在发布此问题之前，我特意删除了环境名称/ pws。

It seems there is an indentation issue in my yml file. I read some other questions on here, and tried various indentation schemes. I still cannot get it to work. I purposely removed the env names/pws before posting this question.

version: '2'
  ghost:
    image: ghost:latest
    container_name: ghost-blog  #Specify a custom container name, rather than a generated default name.
    environment:
      - NODE_ENV=production
      - MYSQL_DATABASE=db-name # Change {{db-name}}
      - MYSQL_USER=user # Change {{username}}
      - MYSQL_PASSWORD=pass # Change {{db-password}}
      # - "MAILGUN_USER={{mailgun-user}}" # Change {{mailgun-user}}
      # - "MAILGUN_PASSWORD={{mailgun-password}}" # Change {{mailgun-password}}
    volumes:
      - ./ghost:/var/lib/ghost # persist the data
    ports:
      - 2368:2368
    depends_on:
      - mysql # ensure that the database will start first
    restart: always

  mysql:
    image: mysql:latest
    container_name: ghost-db
    environment:
      - MYSQL_DATABASE=dbname # Change {{db-name}}
      - MYSQL_ROOT_PASSWORD=db-pass # Change {{root-password}}
      - MYSQL_USER=user # Change {{username}}
      - MYSQL_PASSWORD=sq-pass # Change {{db-password}}
    volumes:
      - ./db:/var/lib/mysql
    restart: always
