Friends, i'm making another try of running a YouTube channel about #softwareengineering and #systemdesign The 4th one)
I will start with rubric #ANDevHowTo and will be telling about different interesting small stuff that helping be a better dev and optimize your work and emotional experience.
I will also duplicate all this content to Linkedin and my #GitHub https://lnkd.in/eSPEMKyj Don't forget to Follow & Set a Star :)
And today we will start from #Networking and #MulticastDNS
You can find full article here: https://lnkd.in/e6VhCJmb

PS: I will add youtube channel a bit later, so for now I will start from articles

🖥 Today in our #ANDevHowTo rubric we will start demystify how #Kubernetes #networking works and will emulate it with local #Linux tools. And in the end we will try to write our own CNI plugin for #K8S
Will start from the simple one - container to container connection on the same pod.
❓ Also have small question: What command should be added to give ability to run request to the containers(pod) through the host ip 192.168.0.15?
Here is article:

Proceeding on demystifying #Kubernetes #networking.
In previous post we described the scheme and network setup for many containers in one pod. In this one we will describe how to link pods on the same node
Basically we have the same setup like in previous post, as we just adding one more pod. But the crucial part is #iptables rules for routing packages from one #networknamespace to another connecting 2 #veth pairs.
Remember that by default Kubernetes use iptables over #IPVS. An on big clusters better to switch to the IPVS as it more faster. You can do this by modyfing #ConfigMap of #KubeProxy

In the next post we will connect containers on different nodes. Stay in touch.

Proceeding on demystifying #Kubernetes #networking.
In previous post we described the scheme and network setup for container to container communication in 2 different pods on the same node. In this one we will describe how to link pods and containers on different nodes
Basically we have the same setup like in previous post, as we just adding one more node. But we additionally added bridge ip and routing pod<->bridge<->interface<->additional nodes
Here is full article: https://github.com/creotiv/articles/blob/main/DevOps/K8S/Networking/package_routing_inside_the_k8s.md
In the next post we will connect containers on different nodes using #K8S #Service. Stay in touch.
