      Constrain the size of Docker logs · bd54b991
      Doug Szumski authored
      Even though Kolla services are configured to log output to file rather than
      stdout, some stdout still occurs when for example the container re(starts).
      Since the Docker logs are not constrained in size, they can fill up the
      docker volumes drive and bring down the host. One example of when this is
      particularly problematic is when Fluentd cannot parse a log message. The
      warning output is written to the Docker log and in production we have seen
      it eat 100GB of disk space in less than a day. We could configure Fluentd
      not to do this, but the problem may still occur via another mechanism.
