Cilium IPAM

Kubernetes pods are transient resources with dynamic IP addresses. For this reason, IPAM is a central component of Kubernetes administration.

In tunneling mode, Kubernetes IPAM is usually configured to distribute IP addresses from a reserved private range, which is the most simple option.

In direct routing mode, where the aim is to integrate the Kubernetes platform into the underlying network fabric, IPAM can become more complex and require more advanced options.

In this lab, we will explore the various IPAM options provided by Cilium.
