Question

我安装了Docker CE，并且在新安装的Ubuntu（18.10）上安装了docker compose。从那以后，我在用docker-compose挂载卷时遇到了一个错误。我确定我使用的docker-compose与以前的笔记本电脑（在Ubuntu 16.04上运行）相同。从主目录装载的卷都为空，并且权限不好。

version: '3.3'

# We define volumes here.
# In this case, we define a volume for the database but it's overkill
# because we used this volume only with one container.
volumes:
  db-volume:

# We define containers here
services:

  # DB container
  db:
    # We use the image of mariadb (https://hub.docker.com/_/mariadb/).
    # Like we don't precise tag, it's the latest version image which is           download.
    image: mariadb
    # We define environment variable like explained in the documentation of the image.
    environment:
      - MYSQL_ROOT_PASSWORD=root_password
      - MYSQL_DATABASE=${DATABASE_NAME}
      - MYSQL_USER=drupal
      - MYSQL_PASSWORD=drupal
    # We used the volume previously defined.
    volumes:
      - db-volume:/var/lib/mysql

    php-cli:
    # Here, we use a Dockerfile and not a Docker Image. The file is Dockerfile-php-cli and is in the same repository
    # than the docker-compose.yml
    build:
      context: .
      dockerfile: Dockerfile-php-cli
      # Arguments pass to the Dockerfile.
      args:
        USER_UID: ${USER_UID}
    volumes:
      # Data of application
      - ./:/var/www/html:rw
      # Share the local user's npm cache as a Docker volume
      - ~/.npm:/home/php/.npm:rw
      # Share the local user's SSH keys and configuration (read-only)

      # Share the local user's known_host
      - ~/.ssh/known_hosts:/home/php/.ssh/known_hosts:rw
      # Share the local user's gitconfig
      - ~/.gitconfig:/home/php/.gitconfig
    environment:
      # We define the PATH and add the bin directory of vendor.
      - PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/var/www/html/vendor/bin

我尝试将docker-compose更改为使用长语法，但我遇到了这个错误：

实际上，文件.ssh / known_hosts是容器php-cli上的目录。

我不明白发生了什么事。
