Update Dockerfile to fix dependency problems

[chao-peng]

The old base image does not exist on Docker Hub and consequently leads to the build failure. I've changed it to the golang official base image. Commands for building the project have also been fixed.

You can find the dockerfiles of base images under directory base. golang_nodejs may be what you want. You can compile the dockerfile inside to make golang_nodejs images by yourself.
