在 docker compose 中不使用 "sleep infinity" 命令启动远程容器

Question

在 VS Code 中使用远程容器，我想在没有默认 sleep infinity 命令的情况下启动一个 Ubuntu 容器（稍后启动 Flask 服务器），这样我以后可以从主持人。

TL;DR

如果我从 docker-compose.yml 中删除 sleep infinity 命令，容器将无法启动，例如。 G。

Run: docker exec 12d95e1f14877bc4af7fa62e59f81b7ebf0f8983aa357eb077a09bf1951e4370 test -d /root/.vscode-server
Error response from daemon: Container 12d95e1f14877bc4af7fa62e59f81b7ebf0f8983aa357eb077a09bf1951e4370 is not running

.. 但是使用 sleep infinity 命令，我正在启动的 Flask 服务器无法使用 devsettings.json.

中的 appPort 转发它的端口

Setup

VS Code 容器的图像：Docker in Docker compose

图像在其 Docker 文件中：ubuntu:bionic

Dockerfile

FROM ubuntu:bionic

# Avoid warnings by switching to noninteractive
ENV DEBIAN_FRONTEND=noninteractive

# Docker Compose version
ARG COMPOSE_VERSION=1.24.0
...
# Configure apt and install packages
RUN apt-get update \
    && apt-get -y install --no-install-recommends apt-utils 2>&1 \
    ....

# Switch back to dialog for any ad-hoc use of apt-get
ENV DEBIAN_FRONTEND=dialog

我尝试在Docker文件中添加ENTRYPOINT ["bash", "/bin/bash"]，但是没有效果。

devsettings.json

{
    "name": "Docker in Docker Compose",
    "dockerComposeFile": "docker-compose.yml",
    "service": "my-service",
    "workspaceFolder": "/workspace",

    // default command is "sleep infinity", can't use that as Flask should be accessible
    "overrideCommand": false,

    "appPort": ["5000:5000"],

    "extensions": [
        "peterjausovec.vscode-docker",
        "ms-python.python"
    ],
    "settings": {
        "remote.extensionKind": {
            "peterjausovec.vscode-docker": "workspace"
        }
    }
}

docker-compose.yml

version: '3'
services:
  my-service:
    build: 
      context: .
      dockerfile: Dockerfile

    volumes:
      # Update this to wherever you want VS Code to mount the folder of your project
      - ..:/workspace

      # This lets you avoid setting up Git again in the container
      - ~/.gitconfig:/root/.gitconfig

      # Forwards the local Docker socket to the container.
      - /var/run/docker.sock:/var/run/docker.sock 

    # Overrides default command so things don't shut down after the process ends.
    command: sleep infinity

Answer 1

它不起作用的原因是你没有在 docker-compose.yml 中公开端口。

语法是：

services:
  service_name:
    ports:
      - "8080:80"

尝试使用命令启动 jupyter notebook 时遇到类似情况，找到了一种解决方法，将 sleep inifinity 放在最后。

./docker-compose.yml

....
ports:
      - 8888:8888    
command: bash -c "jupyter notebook --ip 0.0.0.0 --port 8888 --no-browser --allow-root && sleep infinity"
