#  This is a script that does the following:
#  * Pull madlib/postgres_10:$IMAGE_TAG(default tag is `latest`) from docker;
#  * Mount your local madlib directory to docker container;
#  * Name your docker container as $CONTAINER_NAME (default name is madlib)
#  * Build madlib from source; build dir is /madlib/build_docker which 
#    is mounted to your local madlib dir
#  * Install madlib and run install check;
#  * Log in to docker container from shell as postgres user, so that you
#    can run psql and start using madlib from here
#
# Note: you have to run this script inside your local MADlib repo
# Example command:
# CONTAINER_NAME=my_madlib IMAGE_TAG=LaTex ./tool/docker_start.sh
