Azure AKS : Azure CNI Demo

docs.microsoft.com/en-us/azur...
Use kubenet when:
You have limited IP address space.
Most of the pod communication is within the cluster.
You don't need advanced AKS features such as virtual nodes or Azure Network Policy. Use Calico network policies.
Use Azure CNI when:
You have available IP address space.
Most of the pod communication is to resources outside of the cluster.
You don't want to manage the UDRs.
You need AKS advanced features such as virtual nodes or Azure Network Policy. Use Calico network policies.

Thank you 🙂

[@manojpunia7717]

can you please help to get the azure documentation where it is mentioned the pods will be assigned from cluster subnet only. not from any other subnet?

[@PachehraTalks]

IP addresses for the pods and the cluster's nodes are assigned from the specified subnet within the virtual network. Each node is configured with a primary IP address. Azure CNI preconfigures 30 extra IP addresses by default. These IP addresses are assigned to pods scheduled on the node. When you scale out your cluster, each node is similarly configured with IP addresses from the subnet. learn.microsoft.com/en-us/azure/aks/azure-cni-overview#plan-ip-addressing-for-your-cluster

it helped, thanks!

[@tigerdeccan]

why docker bridge need /16 range - its a bit too big

[@PachehraTalks]

Its by default - you can change it moreover it shouldnt impact anything as communication Ips are from Vnet

[@tigerdeccan]

@@PachehraTalks I tried in non prod environments. But for prod I’m using /16 in case of MS support says it not supported scenario . So far I haven’t had issues . It’s always hard to convince networking folks
