Come hang out with Joe Beda as he does a bit of hands on exploration of Kubernetes and related topics. Some of this will be Joe talking about the things he knows well. Some of this will be Joe exploring something new with the audience. Ask questions, comment and help decide where things go.

In this post-KubeCon episode we'll cover some impressions from the conference and announcements from other CoreOS/Redhat, Microsoft and beyond. Then we'll dive into the idea of "GitOps" and how those ideas are used in WeaveWorks Flux.
