Usage: build.sh [options]

Builds the fully-loaded container using Google Cloud Container Builder.

Required options:
    -p|--project            GCP project ID
    -c|--container          docker container name
    -t|--tag                docker tag for the image

Optional options:
    -a|--async              asynchronous execute Cloud Container Builder

For example, running:
$ build.sh -p my-gcp-project -c debian8-clang-fully-loaded -t latest
will produce docker images:
    gcr.io/my-gcp-project/debian8-clang-fully-loaded:latest
