# Dockerfile for Symas OpenLDAP
FROM debian:jessie

LABEL vendor="Symas Corporation" \
    symas.openldap.version="2.4.44.5" \
    symas.openldap.edition="Gold" \
    symas.openldap.arch="amd64"

# Install Symas OpenLDAP
COPY symas-openldap-gold.64_2.4.44-5_amd64.deb /    
RUN dpkg -i symas-openldap-gold.64_2.4.44-5_amd64.deb \
    && rm -f symas-openldap-gold.64_2.4.44-5_amd64.deb

# Add your configuration
COPY symas-openldap.conf /opt/symas/etc/openldap

# If using slapd.conf
COPY slapd.conf /opt/symas/etc/openldap

# If using cn=config...
#COPY my_cn-config.ldif /tmp
#RUN mkdir /opt/symas/etc/openldap/slapd.d && \
#    /opt/symas/bin/slapadd -l /tmp/my_cn-config.ldif -F /opt/symas/etc/openldap/slapd.d -q && \
#    rm /tmp/my_cn-config.ldif

# This creates the data directory in the container
VOLUME /var/symas/openldap-data

# The ports to make available
EXPOSE 389 636

# This starts slapd when the container starts. The "-d 0" is required to keep
# the slapd process in the foreground. If slapd were to go to the background, 
# docker will assume slapd is done running and will quit.
CMD ["/opt/symas/etc/solserver", "start", "-d 0"]

# That's it
