gcp-build.sh

#!/usr/bin/env bash

# This is a script that will build the app on a gcp machine. It uses Google Cloud Build to
# do the actual build, stores the build artifacts in a bucket, then copies those artifacts to their
# proper local directory.

# Permissions:
# This script requires that the service account for the instance can run build command and access buckets
# This script reauires that the instance has the ability to make API calls to gcp

# You can always build locally, but the f1-micro instance doesn't have enough resources to complete
# the build successfully, hence this script.
