docker :dind (ports) 上的 Docker Compose 错误 "TypeError: expected string or buffer"

Question

我正在尝试在 docker 容器 (docker:dind) 中使用 docker-compose 设置我的容器，以便在 gitlab ci 上进行测试。

从昨天到今天，它开始在“docker-compose up”上失败，我将错误减少到 docker-compose.yml 中服务的“端口”段。失败的最简单配置是:

version: '3':
services:
        ubuntu:
                image: ubuntu:latest
                ports:
                        - 80:80

我试过没有端口，它的工作原理。

具体错误是这样的:

ERROR: for ubuntu  expected string or buffer
Traceback (most recent call last):
  File "/usr/bin/docker-compose", line 11, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/site-packages/compose/cli/main.py", line 68, in main
    command()
  File "/usr/lib/python2.7/site-packages/compose/cli/main.py", line 118, in perform_command
    handler(command, command_options)
  File "/usr/lib/python2.7/site-packages/compose/cli/main.py", line 926, in up
    scale_override=parse_scale_args(options['--scale']),
  File "/usr/lib/python2.7/site-packages/compose/project.py", line 424, in up
    get_deps
  File "/usr/lib/python2.7/site-packages/compose/parallel.py", line 69, in parallel_execute
    raise error_to_reraise
TypeError: expected string or buffer

这是重现它的步骤:

(at your machine)
~ docker run --privileged -d docker:stable-dind
~ docker exec -ti *CONTAINER_ID* sh

(inside of the docker container)

~ apk add --no-cache py-pip vim
~ pip install docker-compose

(here edit a docker-compose.yml and paste the up yaml code)

~ docker-compose up

不知道是不是python的问题，docker、docker-compose ....

任何人都可以帮助我吗？

谢谢!

我在使用 时遇到了类似的错误NestJS 申请在 macOS .
当我运行命令时 docker-compose up我收到错误:

这是我解决它的方法
我查了 docker-compose.yml文件，我意识到它没有 容器港口指定的。这是文件的样子:

version: "3"
services:
  web:
    image: my-app
    build: .
    container_name: my-app
    ports:
      - 8080:
    env_file: .env
    volumes:
      - ".:/app"

我所要做的就是添加 容器港口这是 3001 :

version: "3"
services:
  web:
    image: my-app
    build: .
    container_name: my-app
    ports:
      - 8080:3001
    env_file: .env
    volumes:
      - ".:/app"

就这些
