# export DATABASE_PASSWORD=password_here
# export DATABASE_NAME=database_name_here
# export DATABASE_ROOT_PASSWORD=database_root_password
# ```

# Install pg (9.1)
PGSQL=$(docker run -p 5432 -d synthomat/pgsql /usr/bin/start_pgsql.sh $DATABASE_ROOT_PASSWORD)
DATABASE_IP=$(docker inspect $PGSQL | grep IPAddress | awk '{ print $2 }' | tr -d ',"')
echo "Database IP: $DATABASE_IP"

# Create .pgpass
echo "$DATABASE_IP:5432:$DATABASE_NAME:$DATABASE_USER:$DATABASE_PASSWORD" > ~/.pgpass
echo "$DATABASE_IP:5432:postgres:root:$DATABASE_ROOT_PASSWORD" >> ~/.pgpass
chmod 600 ~/.pgpass

sleep 5

createdb --username=root -h $DATABASE_IP $DATABASE_NAME
createuser --login --username=root -h $DATABASE_IP $DATABASE_USER
