Ensure ENI multiple IP mode support for Kubernetes Cluster

MediaNivel 1Revisión manualalibaba

Descripción

Alibaba Cloud ENI (Elastic Network Interface) has supported assign ranges of internal IP addresses as aliases to a single virtual machine's ENI network interfaces. This is useful if you have lots of services running on a VM and you want to assign each service a different IP address without quota limitation. With the feature of ENI multiple IP mode, Kubernetes Engine clusters can allocate IP addresses from a CIDR block known to Terway network plugin. Reported as a manual review item: the benchmark audit needs console review or organisational judgement.
