           WORKDIR /usr/src/app 
        
           COPY client/package.json client/yarn.lock ./

After automation is built, revist building frontend and backend in 2 separate containers.

Steps:

- Break apart dockerfile into two files: frontend and backend.
- Build Docker compose file for local testing
- Create a deployment with the two new containers
- Deploy new containers
- Test deployments
- Update CI/CD with new deployments

	WORKDIR /usr/src/app
	COPY client/package.json client/yarn.lock ./
	RUN yarn
	COPY client/. ./
	RUN yarn build
