VSCode 远程容器 - 未使用 docker-compose 在开发容器上安装扩展

Question

我无法使用“远程 - 容器”在开发容器中安装扩展。我不知道这是一个错误，我的配置不正确，还是预期的行为。下面是我当前的配置，这两个文件都位于项目的根文件夹中。

docker-compose.yml

version: "3.7"

services:
  api:
    image: node:12
    restart: always
    ports:
      - ${API_PORT}:3000
    volumes:
      - .:/usr/app
      - /usr/app/node_modules
    working_dir: /usr/app
    command: bash -c "yarn && yarn dev"

.devcontainer.json

version: "3.7"

services:
  api:
    image: node:12
    restart: always
    ports:
      - ${API_PORT}:3000
    volumes:
      - .:/usr/app
      - /usr/app/node_modules
    working_dir: /usr/app
    command: bash -c "yarn && yarn dev"

中列出的扩展列表.devontainer.json是我想安装在开发容器中的扩展。任何帮助表示赞赏！

According to the Visual Studio Code documentation, the two files need to be located in a directory .devcontainer in the workspace root.

I still had issues installing the extensions while working from behind a corporate proxy. The solution was to give the container access to the proxy server:

If you use an authenticating proxy like Cntlm on your local machine, configure it to listen on 172.17.0.1 (the Docker interface). Then define the http_proxy and https_proxy environment variables for the container. For example, in devcontainer.json:

"containerEnv": { 
  "http_proxy": "http://172.17.0.1:3128",
  "https_proxy": "http://172.17.0.1:3128"
}

Or in docker-compose.yaml

"containerEnv": { 
  "http_proxy": "http://172.17.0.1:3128",
  "https_proxy": "http://172.17.0.1:3128"
}

Or configure docker-compose.yaml to make the container use the host network:

services:
  devcontainer:
    environment:
      http_proxy: http://172.17.0.1:3128
      https_proxy: http://172.17.0.1:3128

Then you can just pass the same proxy variables into the container as used on the host. For example, in the docker-compose.yaml:

services:
  devcontainer:
    network_mode: host

如果您使用的不是本地代理，而是网络内部的远程代理，则无论容器的网络配置（主机或默认）如何，您都可以执行后者。
