Hi I followed the instructions in the readme, but I got an from the client container:

    client_1       | Could not find module "@angular-devkit/build-angular" from "/app".
    client_1       | Error: Could not find module "@angular-devkit/build-angular" from "/app".

My dirty workaround was to execute

npm install --save-dev @angular-devkit/build-angular

from the host inside the "back-end" folder
