docker文件卷映射问题(docker-compose)

docker-compose.yml示例文件：

version: '3'
services:

  oceanmind_ai:
    image: aarch64_pdf2word:v1.4
    container_name: oceanmind_ai
    restart: always
    entrypoint: sh /home/rhino/oceanmind_ai/start.sh
    environment:
      - LANG=zh_CN.utf8
      - TZ=Asia/Shanghai
    ports:
      - "7032:7031"
    volumes:
      - ./config/oceanmind_ai20240301:/home/rhino/oceanmind_ai
      - /etc/hosts:/etc/hosts
      - ./test20240305.txt:/home/rhino/test20240305.txt
      - ./service_check.py:/home/rhino/oceanmind_ai/service_check.py
    networks:
      - sinovatio

########## shared network ##########
networks:
  sinovatio:
    external: false
########## shared network ##########

情形假设：

1. 宿主机和容器均存在该文件：

   /etc/hosts:/etc/hosts:文件会被同步

2. 宿主机存在，容器不存在：

   ./test20240305.txt:/home/rhino/test20240305.txt:容器内会创建该文件

3. 宿主机不存在，容器存在

   ./service_check.py:/home/rhino/oceanmind_ai/service_check.py:貌似不被允许

   Error response from daemon: OCI runtime create failed: container_linux.go:318: starting container process caused "process_linux.go:378: container init caused \"rootfs_linux.go:60: mounting \\\"/home/xsg/docker_manage/service_check.py\\\" to rootfs \\\"/home/data01/docker/overlay2/5a286c8dd3f877225a425a29d52081208e286a6f3f09d11118c13cb490645bb0/merged\\\" at \\\"/home/data01/docker/overlay2/5a286c8dd3f877225a425a29d52081208e286a6f3f09d11118c13cb490645bb0/merged/home/rhino/oceanmind_ai/service_check.py\\\" caused \\\"not a directory\\\"\"": unknown: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

   这个错误是因为你试图将一个目录挂载到一个文件上，或者将一个文件挂载到一个目录上。请检查指定的主机路径是否存在并且是预期的类型。

4. 宿主机和容器都被存在

   两端均会自动创建文件夹，注意，是文件夹，而不是目录，即时该路径有后缀

   ./test20240305.txt:/home/rhino/test20240305.txt
