Vscode not detecting git folder after build - Docker

Question

I am new to Docker and buidling a docker-compose file to setup my nodejs dev environment from a single file. Idea is to give a docker-compose file to a developer from where they can simply spin up the containers and start development.

When I docker-compose up, the application is built and runs with success. But my problem is when I open it in dev containers in Vscode, it fails to recognize as a git repo.

.dockerignore

node_modules
npm-debug.log

Dockerfile

FROM node:16.15.0 as develop-stage
WORKDIR /code
COPY package.json .
# Using package-lock file to fix the version of installed modules.
COPY package-lock.json .
RUN npm install
COPY . .
EXPOSE 9608
CMD ['nodemon' 'index.js']

Docker-compose

version: '3.8'
services:
  my-service:
    container_name: my-service
    build: 
      context: 'https://username:[email protected]/abc/test-repo'
      dockerfile: Dockerfile
    volumes:
      - my-data:/code
    command: nodemon index.js
    networks:
      - my-network
    expose:
      - 9608
    ports:
      - 9608:9608
    restart: on-failure
volumes:
  my-data:
    external: false
networks:
  my-network:
    external: false

When running ls -a inside the container on the root folder do you see a .git folder? — brianangulo

Do you have a .dockerignore file, and if so what does it contain? — 1615903

@1615903 I have udpated my question with a dockerignore file. — power-cut

What if you try to explicitly copy it: COPY .git/ ./.git/? — 1615903

Your .git folder is not within the root directory that's being copied over to the docker image. Depending on how your folder structure is set up it may be a folder or 2 above. You can find it by cd .. && ls -a until found. Then use an explicit COPY ../.git . to add it into the Docker image.

Couldnt find the git folder in the image. or maybe dockerfile copies "visible" folder ?

Updated my answer. I meant within your root directory before it gets copied over to the docker image. Your .git folder holds all of the git metadata so the goal is to find out where it is and COPY it into the image. Sometimes if you set up your folder as below so where is it? ` app/ .git/ <--- your git folder code/ <--- your app here package.json index.js `
