docker pull files from package.json - docker

Question

I have simple node.app, with this package.json:
{
"name": "docker_web_app",
"version": "1.0.0",
"description": "Node.js on Docker",
"author": "xxxxx",
"main": "server.js",
"scripts": {
"start": "node server.js"
},
"dependencies": {
"express": "^4.16.1",
"myuser-deploy": "git+ssh://git#github.com:myuser/deploy.git"
}
}
Normally when I run "npm i", it installs all dependencies, and also the one form the github. I have SSH that I previously setup with the github. All works fine so far.
Now I added Docker support for my application, like this
Dockerfile:
FROM node:carbon
# Create app directory
WORKDIR /usr/src/app
# Install app dependencies
# A wildcard is used to ensure both package.json AND package-lock.json are copied
# where available (npm#5+)
COPY package*.json ./
RUN npm install
# If you are building your code for production
# RUN npm install --only=production
# Bundle app source
COPY . .
EXPOSE 8080
CMD [ "npm", "start" ]
docker-compose.yml:
version: "3"
services:
test-service:
build: .
image: test-service
container_name: test-service
working_dir: /usr/src/app
user: node
restart: always
ports:
- '3001:3000'
When I run docker-compose up, it gives me this error:
> npm ERR! Error while executing: npm ERR! /usr/bin/git ls-remote -h -t

What can I do with the docker, so it uses my SSH keys?
