Amazon VPC Container Networking Interface (CNI) Plugin version 1.6 is now available for use by Kubernetes clusters running on AWS.
Version 1.6 of the open source Amazon VPC CNI plugin includes a new MINIMUM_IP_TARGET parameter that can be used to reduce pod start time while minimizing IP addresses allocated to nodes. Support for peered VPCs is improved with a new parameter AWS_VPC_K8S_CNI_EXCLUDE_SNAT_CIDRS that allows CIDR ranges to be excluded from Source Network Address Translation (SNAT). Additionally, v1.6 includes a number of bug fixes around ENI allocation and EC2 API call rates to improve overall reliability and performance.
To learn more, see the Amazon VPC CNI v1.6 release notes on GitHub. You can upgrade existing clusters to use version 1.6 by following the instructions in the Amazon EKS documentation. As we confirm stability, VPC CNI v1.6 will be set as the default for new Kubernetes clusters launched by Amazon EKS.
