Julia Evans excellent blog post focusing on how to set up your Kubernetes network. She hasn’t had seen much about how to operate the network and be confident that it would not create a lot of production incidents for you down the line. And that’s why she dives into kubernetes networking in this post.
She tries to home in at these things:
- Avoiding networking outages in production is important
- Operating networking software is hard
- Thinking critically about major changes to your networking infrastructure and the impact on your API integration
Amongst some interesting points made is a notion that networking software often relies very heavily on the Linux kernel. And to fix a production networking issues you often need a lot of expertise. She feels like as an organization running your own Kubernetes cluster you need to make a pretty large investment into making sure you understand all the pieces so that you can fix things when they break.
Good coverage of the kubernetes networking topic from newcomer perspective with some example code.
