Here's my docker file for running a postgres 9.3 with plv8

    FROM    boothead/saucy

    ENV     DEBIAN_FRONTEND noninteractive

    # Add repository and install PostgreSQL 9.3
    RUN     echo "deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main 9.3" >> /etc/apt/sources.list
    RUN     apt-get update
    RUN     apt-get -y --force-yes -f install postgresql-9.3 postgresql-client-9.3 libicu48 wget

    RUN     wget http://www.mirrorservice.org/sites/archive.ubuntu.com/ubuntu//pool/universe/libv/libv8/libv8-3.7.12.22_3.7.12.22-3_amd64.deb
    RUN     dpkg -i libv8-3.7.12.22_3.7.12.22-3_amd64.deb
    RUN     apt-get -y --force-yes -f install postgresql-9.3-plv8


    # Postgres is started now, shut it down and replace config
    RUN     service postgresql stop
    ADD     pg_hba.conf     /etc/postgresql/9.3/main/
    ADD     pg_ident.conf   /etc/postgresql/9.3/main/
    ADD     postgresql.conf /etc/postgresql/9.3/main/

    # Create superuser, tempo db and plv8 language
    ADD     create_user.sh /
    RUN     /bin/bash /create_user.sh
    RUN     rm /create_user.sh

    # Configure for running in container
    EXPOSE  5432
    # VOLUME ["/var/lib/postgresql/9.3/main"]
    CMD     ["/bin/su", "postgres", "-c", "/usr/lib/postgresql/9.3/bin/postgres -D /var/lib/postgresql/9.3/main -c config_file=/etc/postgresql/9.3/main/postgresql.conf"]

create_user.sh is basically service postgresql start; su echo <SQL> | psql; service postgresql stop;

This is fine for me to spin up a postgres instance at some known state for development, but it's a bit dissatisfying for managing the data separately from the container. Anyone got any tips for integrating volumes with this?
