CMD [ "node", "dist/main.js" ]

docker-compose

services:
  api:
    build:
      dockerfile: Dockerfile
      context: .
      target: build
    volumes:
      - .:/usr/src/app
      - /usr/src/app/node_modules
      - /usr/src/app/dist

    command: yarn run start:prod
    ports:
      - 4800:4800

Start

docker-compose up -d -V --build
