Show Overview: Brian and Tyler talk about Kubernetes Networking and Kubernetes Storage.
Show Notes:

Topic 1 - Let’s talk about the challenges of networking with containers and some of the ways that Kubernetes addresses these challenges.

There’s lots of different ways to network containers together. Kubernetes does some basic networking (by default), and then there are add-on options for more complex, secure scenarios.
The role of DNS in Kubernetes networking (services, etc.)
Kubernetes network plugins (CNI: container network interface)
Ingress and Egress Routes, Services, Load Balancing
Network Policy (fine-grained traffic control)

Topic 2 - Let’s talk about the challenges of storage with containers and some of the ways that Kubernetes addresses these challenges.

There’s definitely a misperception that containers should only be used for stateless applications.
Containers are (primarily) Linux, and Linux has well known concepts about how to interact with persistent storage.
Containers need a way to interact with persistent storage in a model where it can be dynamically allocated.
Kubernetes storage plugin proposal (CSI: container storage interface)
