Question

ERROR: yaml.parser.ParserError: while parsing a block mapping in "./docker-compose.yml", line 1, column 1
expected <block end>, but found '<block mapping start>' in "./docker-compose.yml", line 2, column 3

我的yml文件中似乎存在缩进问题。我在这里阅读了其他一些问题，并尝试了各种缩进方案。我仍然无法让它发挥作用。在发布此问题之前，我故意删除了env名称/ pws。

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

将来，您可以使用此website来检查它有什么问题，然后随时修复。

修改

所以你的docker-compose文件遇到的问题如下：

您没有在版本之后添加服务：并且

如果您想要最新的图像，则不必传递：latest 标记，当您需要特定版本的图像时，您将传递标记，并且在“ “

至于代码，它应该如下：

version: '2' services: ghost: image: ghost container_name: ghost-blog environment: - NODE_ENV=production - MYSQL_DATABASE=db-name - MYSQL_USER=user - MYSQL_PASSWORD=pass # - "MAILGUN_USER={{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 always start first restart: always mysql: image: mysql 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

Answer 2

在我的情况下，由服务名称之前缺少空格（如mysql）引起的错误。希望这些信息可以帮助别人！

Answer 3

对我来说，问题在于线的缩进不足。我在出现问题的行中添加了一个标签，并在此标签的进一步依赖旁边添加了标签。
