Yet another rsyslog docker container

One syslog to rule them all

1. Build the syslog container:

   docker build -t syslog .

2. Monitor the logs:

   docker run --volumes-from syslog ubuntu tail -f /var/log/syslog

3. Run it:

   docker run --name syslog -d -v /tmp/syslogdev:/dev syslog

4. Start another container to send logs:

   docker run -v /tmp/syslogdev/log:/dev/log ubuntu logger hello

5. Alternative to #2, as of docker v1.3 use the docker-exec command to inspect syslog container directly, after some logs have been generated

   docker exec -t syslog tail -f /var/log/syslog

6. See in the log message show up in the "tail" container.
