I have a Node.js script that I want to put on a cloud server. However, that server may not have Node.js installed, or it may have a different version of Node.js installed. So, I want to run my script in a Docker container.

Start with a Docker Compose file:

# docker-compose.yml
services:
  worker:
    image: node:16
    working_dir: /app
    init: true
    command: yarn start
    restart: always
    volumes:
      - .:/app
      - node_modules:/app/node_modules
volumes:
  node_modules:

Install the dependencies:

docker compose run --rm worker yarn

Run it:

docker compose up
