# define container name and ports
PGSRV=""
PGSRVPORT=""

docker run -d --name ${PGSRV} --env-file POSTGRESENV -p ${PGSRVPORT}:5432 postgres:10-alpine

# specify container name for psql configuration, if needed
PGCLI=""
docker run -d --name ${PGCLI} postgres:10-alpine

# connect using client container, enter password when prompted
PGUSER=""
