Description: Aaron talks with Solomon Hykes (Founder & CTO) and Ben Golub (CEO) of dotCloud about containers as the next big thing in a post-virtual-machine world. We dive into dotCloud’s new product, Docker, and talk about feedback to the project and product at OSCON.

Topic One: Solomon, you’ve been busy! Tell us what has happened since we spoke in November?

Topic Two: I was in your session at OSCON on Docker. It was in a big, packed room and you were mobbed like a rockstar afterwards (and not just for the stickers).  Tell us about your session.  Seems like an active project, over 100 contributors and 2500 commits. Didn’t Docker and dotCloud also recently join the Linux foundation?

Topic Three: I liked a few analogies you brought up in your session.  First was treating an application like a shipping container.  It makes the size and logistics standard no matter how it is transported or deployed. Another one was that virtual machines were hammers and all applications were nails.

Topic Four: Especially in the PaaS space I keep hearing more and more that the end result will be LXC (LinuX Containers) and cgroups instead of VMs. Is this what you're doing under the covers? What are your thoughts on that? Docker uses AUFS (“Another Union File System”) for COW (copy on write), correct? Can you stack containers and how would that work? Deduplication for applications?

Topic Five: Use Cases? As a consumer (user or developer), why would I care?


Join us in exploring application and infrastructure changes required for running scalable, observable, and portable apps on Kubernetes.
