Cello CNI review
A focused, free CNI plugin for Pod networking in Volcengine VPC environments.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Cello CNI is an open-source Kubernetes container network interface plugin for Volcengine VPC environments. It is intended for teams running Kubernetes on Volcengine ECS-backed nodes that need Pod networking through secondary elastic network interfaces. The plugin supports shared-ENI and exclusive-ENI modes, along with Pod-to-Pod and Pod-to-Node communication. Its strongest fit is Volcengine-focused infrastructure rather than a general-purpose networking layer across varied cloud environments.
The networking model is the main reason to consider Cello CNI. It handles secondary ENI allocation and recycling, giving Pods access to Volcengine VPC networking. Cilium integration adds Kubernetes service handling and NetworkPolicy support, while the supported environment includes Kubernetes, Volcengine ECS, veLinux 1.0 and Linux. This combination gives platform teams a focused way to connect Kubernetes workloads with Volcengine networking while retaining policy capabilities through Cilium. Helm-based installation and DaemonSet deployment align with a cluster-managed operating model.
Cello CNI is a practical choice when Volcengine VPC compatibility is the priority and a free, open-source plugin meets the deployment requirements. It is less suitable for teams seeking broad multi-cloud coverage, managed onboarding or a platform that abstracts away self-hosted Linux and Kubernetes operations. Buyers should also evaluate whether shared-ENI or exclusive-ENI behavior matches their Pod networking design. Choose Cello CNI for specialized Volcengine ECS and VPC deployments; choose an alternative when the environment extends beyond its documented platform focus or requires a broader integration ecosystem.
