An experiment – Enable Cilium native routing on Azure Kubernetes Service BYOCNI – Part 1
This is the first part of a three-part series about “An experiment – Enable Cilium native routing on Azure Kubernetes Service BYOCNI”. Cilium supports two routing modes, encapsulation and native routing. Due to its versatility of not depending on the underlying network, the encapsulation, also called tunneling, mode is the default one for most Cilium…

Restrict access to the IMDS endpoint on Azure Kubernetes Service with Cilium
In today’s blog post, we take a look at restricting access to the Azure IMDS endpoint on an Azure Kubernetes Service (AKS) cluster with Cilium using the BYOCNI approach. The Instance Metadata Service (IMDS) endpoint, also known as short IMDS, can be called directly from every Azure VM or VMSS instance via the following command.…
