Docker 容器在启动后立即关闭

Question

我想在我的 Windows 10 机器上为 VSCode 设置学习开发容器，但是当我在 VSCode 中按“打开容器中的文件夹”时，出现错误：

如果我只发出命令：

docker-compose up

容器立即启动和停止，控制台没有任何错误。

我的设置是这样的： Dockerfile:

FROM erlang:latest

WORKDIR /project

CMD tail -f /dev/null

docker-compose.yml:

version: '3'
services:
  development:
    build:
      context: .
    volumes:
      - ./:/project
      - build:/project/_build
      - deps:/project/deps

volumes:
  build:
  deps:

.devcontainer/devcontainer.json:

{
    "name": "Erlang dev container",

    "service": "development",
  
    "context": "..",

    "dockerComposeFile": "..\docker-compose.yml",

    "workspaceFolder": "/project",

    "settings": { 
        "terminal.integrated.shell.linux": "/bin/bash"
    },

    "extensions": []  
}

为什么不起作用？

PS。我什至像这样更改了我的 Dockerfile：

FROM erlang:latest

WORKDIR /project

COPY . .

还有我的docker-compose.yml：

version: '3'
services:
  development:
    build:
      context: .

还是不行。

PSPS。但！之后我在 devcontainer.json 行中更改：

"dockerComposeFile": "..\docker-compose.yml",

至：

"dockerFile": "..\Dockerfile",

然后VSCode才在容器中打开了我的文件夹。但我不想 COPY 。 .在我的 Dockerfile 中，我想将我项目的文件夹作为卷添加到我的 docker-compose.yml 文件中。我该如何管理？

Answer 1

我通过将 tty:true 添加到我的 docker-compose 服务定义中解决了我的问题，如下所示：

version: '3'
services:
  development:
    build:
      context: .
    tty: true
    volumes: 
      - ./:/project
