#  This is a script that does the following:
#  * Pull madlib/postgres_9.6:latest from docker;
#  * Mount your local madlib directory to docker container;
#  * Build madlib from source;
#  * 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 from one level up from your madlib directory, for
# example, ~/workspace which has madlib src directory there
