At Silicon Valley Users Group (SVLUG) tonite, Daniel Klopp, Senior Technical Consultant, Taos Consulting, gave an intermediate talk on “Docker.”
He had some really informative and detailed slides on using Docker, especially his cgroup commands samples.
Some of the interesting things he mentioned were:
- cgroups are nested
- Docker currently has a limit of 127 “layers”, with prior layers appearing to be read-only to the current layer
- Docker is high-level enough to run on multiple operating systems, including both linux and windows
One attendee mentioned that a work-around for the insecure nature of Docker is to combine it with SELinux, though that will involve a fair amount of work.
Over 400 people RSVPed on a related Meetup, and over 150 people attended, a record for this decade.
