  Scaling microservices on Huawei Cloud Container Engine (CCE) should be a seamless operation. However, when utilizing EulerOS node pools under heavy load, teams frequently encounter a critical Huawei Cloud deployment error: node autoscaling triggers successfully, but new Pods remain stuck in a   ContainerCreating   or   Pending   state. Examining the cluster events inevitably reveals Container Network Interface (CNI) IP pool exhaustion. This failure cascade severely impacts Enterprise cloud DevOps pipelines. This article breaks down the architectural constraints causing this issue on Huawei Cloud CCE and provides a definitive, code-backed solution to stabilize your cluster scaling. The Root Cause: VPC-CNI Architecture and Subnet Exhaustion To understand why IP exhaustion occurs when running Kubernetes on EulerOS within CCE, we must look at the underlying network models. CCE offers several networking modes, but high-performance enterprise environments typically ...
