Docker fails to build - Create React App + Tailwind /bin/sh: craco: not found

I've been stuck with this problem for a couple of days now. I am trying to dockerize a django REST API + react (create-react-app) application. The react application uses craco for building since I am using tailwindcss. I followed the this guide to integrate Tailwind with the React app and it's working when I run yarn start locally.

Guide: https://tailwindcss.com/docs/guides/create-react-app

The problem is it is throwing /bin/sh: craco: not found error when I run it using docker-compose. I even tried adding RUN yarn add @craco/craco -g after RUN yarn in the frontend Dockerfile but it is showing the same error.

Error when running docker-compose up --build:

The issue is that you map your host directory and volume onto the directories in the image that contain the node modules and the app files.

Try removing this section in the docker-compose file. That way you won't overwrite what's in the image and craco will be available.

volumes:
  - ./frontend:/app/frontend
  - node-modules:/app/frontend/node_modules

One thing to be aware of when you use docker-compose to both build and run your image, is that the volumes are only mapped during the run phase and not during the build.
