Description: 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)
