Is this a correct statement?

You need to go through the documentation On the other hand, in EKS you can plan for the maximum … Kubenet is a basic component, which is native to Kubernetes and provided by it. Kubernetes default networking provider, kubenet, is a simple network plugin that works with various cloud providers. In AKS, for example, the maximum number of nodes that a cluster can have depends on a couple of variables — whether the node is in a VM State Set or Availability Set and whether cluster networking uses kubenet or the Azure CNI. I'm not sure what the difference is between the CNI plugin and the Kube-proxy in Kubernetes. For instance, when running kubenet in AWS Cloud, you are limited to 50 EC2 instances. Even then, it is still not clear which number takes absolute precedence for certain configurations. Those IPs belong to the NICs of the VMs where those pods run. Network address translation (NAT) is then configured so that the pods can reach resources on the Azure virtual network. Nodes use the Azure CNI plug-in instead of kubenet, which provides Windows containers support and third-party IP address management software and services. Kubernetes CNI vs Kube-proxy. Which can be safely used, and which cannot be used safely.

The plugin assigns IPs to Kubernetes’ components. 4.

It is packaged as a single binary called flanneld and can be installed by default by many common Kubernetes cluster deployment tools and in many Kubernetes distributions.
The easiest a CNI is to set up, the best our first impression would be. As far as I understand kubenet and azure-cni can be used, as they are options in AKS/acs-engine. Network address translation (NAT) is then configured on the nodes, and pods receive an IP address "hidden" behind the node IP. But sometime it can be complicated to have one IP address per pod, for example when you have to deal with very small IP addresses range on the subnet where AKS will … Second - which CNIs can be used, like calico, flannel etc. Compared to some other options, Flannel is relatively easy to install and configure. Azure CNI makes sure that all your pods running in the Kubernetes cluster get an IP address on the subnet, which is great because you can benefit from all the VNET/Subnet features and security rules using NSGs. As we’ve seen in a past article, pods are assigned private IPs from an Azure Virtual Network. In this blog post, we will explore in more technical detail the engineering work that went into enabling Azure Kubernetes Service to work with a combination of Azure CNI for networking and Calico for network policy.
