Docker talk at SVCC’15

Some short notes from a talk from Ted Young on the Docker ecosystem. Slides available here.

BusyBox – a number of use linux tools packaged up in to a single file. “The Swiss Army knife of Embedded Linux”

CoreOS and Red Hat’s Atomic are particularly suited for running containers, work well with (and I think even come preinstalled with) Docker.

VM vs Container. VMs ofter have multiple apps running in them (e.g. a tomcat with multiple apps running it int). With containers it is typically 1 app per container. Containers typically run within a VM (although can run on “raw metal” too). Multiple containers per VM? – I’m not so clear on!

Cgroups may be used to limit and control resource usage.

12 Factor apps – Good practices for building “cloud native” or software-as-a-service apps.
