Manageable Application Containers: Lightning Quick Updates, Scaleable Security, Easy High Availability - Florian Haas, Hastexo

Sign up or log in to save this to your schedule and see who's attending!

Lightweight, container-based virtualization is an excellent alternative to the likes of KVM, and we have a large array of options to choose from: lxc, Docker, rkt, more to come.

However, sysadmins balk at the idea of an operating system in a single image which, rather than ever being updated, only gets rebuilt when needed. The idea of 2,000 Apache containers needing to be rebuilt because OpenSSL has released its latest patch for a security vulnerability is not appealing to most.

In this presentation, we use overlayfs in conjunction with a few configuration options to build a fully functional container environment for potentially hundreds of containers running on the same operating system distribution. We combine this with AppArmor (for MAC) and Pacemaker (for HA) to build a configuration where patches can be applied to hundreds of containers at once, with minimal downtime.
