Possibly depriacted code in go example causes go test fail in docker image

[Nouri-Alnahawi]

While building the docker image directly inside the kluster (Chapter 8 Page 158) the following error message appears:

/go-demo-2 # docker image build -t vfarcic/go-demo-2:beta .

FAIL	_/src [build failed]
The command '/bin/sh -c go test --cover -v ./... --run UnitTest' returned a non-zero code: 2

I have looked up the issue in Go forums, and maybe the library packages pulled during the build do not support this usage of Prometheus.

Thank you for letting me know that there is an issue. It's been a while since I used that repository. It should be fixed now. Can you please pull the latest code of go-demo-2 and try again?

Thank you for the quick fix. It's working now!
