Random Thoughts: Hardened Docker Container, Unikernel and SGX

Recently I read several interesting research and analyst papers on Docker container security.

SCONE: Secure Containers using Intel SGX describes an implementation of putting Container in the secure enclave, without extensive footprint and performance loss.

Hardening Linux Container is a very comprehensive analysis of Containers, virtualization, and underlying technologies. I find it very rewarding to read it twice. So is the other white paper Abusing Privileged and Unprivileged Linux Containers.

So far all these are based on Docker Containers that runs on top of a general purpose OS (Linux). There are limitations and false claims.

What about running an unikernel in SGX? It is entirely possible, per Solo5. And what about the next step to make unikernel, running inside SGX, a new container runtime for Kubernetes, just like Docker, rkt, and hyper?

  1. Thanks for sharing your thoughts. It is encouraging to see that people are exploring the intersection between Containers and SGX.
