Docker container closes immediately after start

Question

I want to setup learning development container for VSCode on my Windows 10 machine, but when I press "Open Folder in a Container" in VSCode I get an error:

Error response from daemon: Container 03d485c0d0b08ae5af7bc81124f9205d933ce77441829cfcf176a6dd767ab291 is not running

And if I just issue command:

docker-compose up

The container is started and stopped immediately without any errors in console.

My setting is like this: 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": []  
}

Why doesn't it work?

PS. I even changed my Dockerfile like this:

FROM erlang:latest

WORKDIR /project

COPY . .

And my docker-compose.yml to this:

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

And it still doesn't work.

PS PS. But! When after that I changed in devcontainer.json line:

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

to:

"dockerFile": "..\\Dockerfile",

Only then my folder was opened in the container by VSCode. But I don't want to COPY . . inside my Dockerfile, I want to add my project's folder as a volume in my docker-compose.yml file. How do I manage this?

Answer 1

I solved my problem by adding tty:true to my docker-compose service definition, like this:

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