How to install VS Code extensions in a Dockerfile?

Question

Is there a way to install VS Code extensions in a Dockerfile?

Answer 1

If your goal is not to repeat the installation of the VS code extensions, my suggestion is to mount $HOME/.vscode-server/.

For example, in a docker-compose.yml

services:
    your_container:
        ...
        volumes:
            - ./volume/vscode-server:$HOME/.vscode-server

Or in docker run

docker run -it -v ./volume/vscode-server:$HOME/.vscode-server your_image bash

Then, install the required extensions inside the container. The next time you set up the container, there will be no need to reinstall extensions.
