# Set up non-root user, 'build', with default uid:gid
# This allows passing --build-arg to use localhost username, and uid:gid:
#   $ docker build \
#       -t cassandra-website-ui:latest \
#       --build-arg BUILD_USER_ARG=$(whoami) \
#       --build-arg UID_ARG=$(id -u) \
#       --build-arg GID_ARG=$(id -g) \
#       .
#
# Other container parameters can be overridden at build time as well:
#  - NODE_VERSION_ARG:              Version of node to use.
