# This script builds and pushes a Docker image containing
# the Code Search UI to Google Container Registry. It automatically tags
# a unique image for every run.
#
# Also note the PUBLIC_URL endpoint which can either be an FQDN or a path
# prefix to be used for the JS files in the React Application. It defaults
# to "/code-search" which means the search server will be accessible at
# https://PUBLIC_HOSTNAME/code-search.
