# VERSION: 0.1
# DESCRIPTION: Create data image sharing /data volume
# AUTHOR: Daniel Mizyrycki <daniel@dotcloud.com>
# COMMENTS:
# This image is used as base for all data containers.
# /data volume is owned by sysadmin.
# USAGE:
# # Download data Dockerfile
# wget http://raw.github.com/dotcloud/docker/master/contrib/desktop-integration/data/Dockerfile
#
# # Build data image
# docker build -t data -rm .
#
# # Create a data container. (eg: iceweasel-data)
# docker run -name iceweasel-data data true
#
# # List data from it
# docker run -volumes-from iceweasel-data busybox ls -al /data
docker-version 0.6.5

# Create a regular user
RUN echo 'sysadmin:x:1000:1000::/data:/bin/sh' >> /etc/passwd
RUN echo 'sysadmin:x:1000:' >> /etc/group
# Create directory for that user
RUN mkdir /data
RUN chown sysadmin.sysadmin /data
# Add content to /data. This will keep sysadmin ownership
RUN touch /data/init_volume
# Create /data volume
