Kubernetes Pod IP Conflict

I recently encountered an interesting case where newly created Pods were assigned the same IP address as existing Pods. This led to a conflict and disrupted the normal accessibility of services within the cluster. Although this situation is not very common, when it does occur, it can be challenging to identify the problem since Kubernetes itself is not responsible for IP allocation. Instead, it relies on the Container Network Interface (CNI) to handle this task, with the Kubelet acting as the intermediary between CNI and Kubernetes. In this blog post, we will simulate an environment to explore this issue and clarify its nature. Once all the mysteries are unraveled, we will examine the potential scenarios in real-world situations where this problem might arise. <a href="https://hwchiu.medium.com/kubernetes-pod-ip-conflict-7b3c6c63ef4f">Read More</a>
