> microservices-demo-front-end@0.0.1 start /usr/src/app
> node server.js

Hi there, Just had a look into this issue

The dockerfile that is used to build the front-end container seems to be the issue
This is located at /test/Dockerfile
after modifying the version of the node image used to 10-alpine
and adding the --unsafe-perm flag to the command used to install phantomjs-prebuilt

the container appears to build and run, and the sock shop displays correctly.

Will submit a fix soon

Just one afterthought: Why would I want to test with a different environment than i am actually deploying on something like Kubernetes etc.? Why isn't there a shared Dockerfile? Why do we need to replicate Dockerfiles and introduce repetitive code?
