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

Kubernetes Network PluginsKubernetes and StorageContainer Native Storage 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)
