Yarn command in docker-compose can't find && command

Question

I'm using docker on one of my vue projects. I want to run the command yarn --silent and yarn serve back to back in my dockerfile, but it doesn't see yarn --silent as command. Any way to fix this?

The code looks like this:

version: "3"

services:
  proxy:
    build: 
      context: ./api
      dockerfile: Dockerfile
    command: yarn start
    volumes:
      - .:/usr/app/
      - /usr/app/node_modules
    container_name: proxy
    ports:
      - "3000:3000"
  app:
    build:
      context: ./app
      dockerfile: Dockerfile
    command: yarn --silent && yarn serve
    ports:
      - "8080:8080"
    container_name: app
    volumes:
       - ./app:/usr/src/app
       - /usr/src/app/node_modules

EDIT

When I change the command to yarn install --silent && yarn serve I get the following error: error 'install' has been replaced with 'add' to add new dependencies. Run "yarn add && yarn serve" instead. but this will not install all dependencies ofcourse

Answer 1

You have not shared your Dockerfile but I assume you have yarn installed in the docker container, have you?

If so, try with replacing your command with the following:

command: bash -c "yarn --silent && yarn serve"

Note: I assume there is bash in your container, if not replace it with with the supported one - sh, etc.
