Kubernetes cluster networking can be more than a bit confusing, even for engineers with hands-on experience working with virtual networks and request routing. These manifests should result in the creation of two pods as part of the hello-world ReplicaSet, and a hello-world service resource with an...
A Guide to the Kubernetes Networking Model - Kevin Sookocheff
Kubernetes' networking model dictates that Pods must be reachable by their IP address across Nodes. That is, the IP address of a Pod is always visible To perform load balancing within the cluster, Kubernetes relies on the networking framework built in to Linux — netfilter. Netfilter is a framework...

Kubernetes Networking Guide for Beginners - Kubernetes Book
Here's my guide to Kubernetes networking for people who aren't networking experts. There are five essential things to understand about networking in If one of the devices does, the bridge will store this information and also forward data to the original back so that its network request is completed.

How To Inspect Kubernetes Networking | DigitalOcean
For a networking-specific overview of Kubernetes, please read Kubernetes Networking Under the Hood. Note: Most of the commands in this tutorial will need to be run as the root user. If you instead use a sudo-enabled user on your Kubernetes nodes, please add sudo to run the commands when...
Kubernetes Networking: How to Write Your Own CNI Plug-in... | Altoros
How much overhead Kubernetes overlay networking adds. It is difficult to answer all of these questions, because in order to really understand Most of the mentioned solutions include container network interface (CNI) plug-ins. These are the cornerstones of Kubernetes networking, and it is...
A Hacker's Guide to Kubernetes Networking - The New Stack
Kubernetes uses CNI plug-ins to orchestrate networking. Every time a POD is initialized or removed, the default CNI plug-in Future Kubernetes versions will treat networks as equal citizens and include network configuration as part of the POD or namespace spec just like memory, CPUs and volumes.

Communicate between pods in kubernetes - Stack Overflow
How do I communicate from a server inside a pod, to other servers in pods behind services? You need to have services for the pod that you want to access. You can just use internal endpoints of the corresponding services of the pod.
One year using Kubernetes in production: Lessons learned
Running Kubernetes in a pre-released version was challenging, and keeping up with (breaking) new releases was almost impossible at times. Development of Kubernetes has been happening at light-speed in the past year, and the community has grown into a legitimate powerhouse of dev talent.
