If you're updating the self-managed cluster uses the IPv6 family) attached to it. provider for your cluster. Replace If you're using version 1.7.0 or later of the Amazon VPC CNI plugin for Kubernetes and If we need more features like isolation between namespaces, IP filtering, traffic mirroring or changing load balancing algorithms then other network plugins should be used. ("NOTE1", "NOTE2" are just comments, you can remove them at your configuration) To use CNI plugins on Kubernetes, you can follow these steps: Install a CNI plugin on your Kubernetes cluster. For anyone who may be looking for this more recently, the most recent docs state that the correct provisioning command (For RBAC-enabled 1.7+) is: Note that there are also instruction docs for older versions/without RBAC, which state: Note that to install RBAC on top of the older version: Thanks for contributing an answer to Stack Overflow!

Open an issue in the GitHub repo if you want to These interactive tutorials let you manage a simple cluster and its containerized applications for yourself. values for any settings, they might be overwritten with Amazon EKS default This tutorial provides a walkthrough of the basics of the Kubernetes cluster orchestration system. A CNI plugin is responsible for inserting a network interface into the container network namespace (e.g., one end of a virtual ethernet (veth) pair) and making any necessary changes on the host (e.g., attaching the other end of the veth into a bridge). that interface.
