The YAML you provided does not generate an error if the spaces there are indeed spaces. So check your YAML for Tab or other hidden characters.

Although not required by the YAML specification, you should consistently indent with the same number of spaces for keys in a mapping (you use 1 and 2 spaces, I recommend two) as well as elements in a sequence (again you use 1 and 2 spaces, I recommend using 0 for sequences that are mapping values).

Try the following with your Dockerfile and docker-compose:

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

Кажется, в моем файле yml есть проблема с отступом. Я прочитал здесь несколько других вопросов и попробовал различные схемы отступов. Я все еще не могу заставить его работать. Я намеренно удалил имена env/pws перед публикацией этого вопроса.

version: '2'

    container_name: ghost-blog  #Specify a custom container name, rather than a generated default name.
    environment:

      # - "MAILGUN_USER={{mailgun-user}}" # Change {{mailgun-user}}
      # - "MAILGUN_PASSWORD={{mailgun-password}}" # Change {{mailgun-password}}

      - ./ghost:/var/lib/ghost # persist the data
    ports:

    restart: always

в будущем, вы можете использовать этот сайт чтобы проверить, что с ним не так, а затем исправить это на ходу.

EDIT:

таким образом, проблемы, которые у вас были с файлом docker-compose, были следующими:

  1. не добавлять услуги: после версии и

  2. вам не нужно проходить :последний тег если вы хотите последнее изображение, вы передадите тег когда вы хотите определенную версию изображения, и это делается между «»

что касается кода, он должен быть следующим:

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

в моем случае ошибка, вызванная отсутствием пространства перед именем службы (например, mysql). Надеюсь, эта информация может помочь кому-то!
