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

Show Notes:

Topic 1 - Let\u2019s talk about the challenges of networking with containers and some of the ways that Kubernetes addresses these challenges.

There\u2019s 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.)\xa0
Kubernetes network plugins (CNI: container network interface)\xa0
Ingress and Egress Routes, Services, Load Balancing\xa0
Network Policy (fine-grained traffic control) \xa0

Topic 2 - Let\u2019s talk about the challenges of storage with containers and some of the ways that Kubernetes addresses these challenges.

There\u2019s definitely a misperception that containers should only be used for stateless applications.\xa0
Containers are (primarily) Linux, and Linux has well known concepts about how to interact with persistent storage.\xa0
Containers need a way to interact with persistent storage in a model where it can be dynamically allocated.\xa0
Kubernetes storage plugin proposal (CSI: container storage interface)
