To keep things simple, the role of a network plugin is to set up the network connectivity so Pods running on different nodes in the cluster can communicate with each other. The Amazon VPC CNI plugin for Kubernetes is the only CNI plugin supported by Amazon EKS. First, create a resource group to create the cluster in: When using an Azure Resource Manager template to deploy, pass none to the networkPlugin parameter to the networkProfile object. There are several other add-ons documented in the deprecated cluster/addons directory. I have installed fresh Kubernetes 1.6.2 master on a single host and now trying to start Flannel using https://github.com/coreos/flannel/blob/master/Documentation/kube-flannel.yml. with the latest version listed in the latest version v1.12.2-eksbuild.1, By using this CNI plugin your Kubernetes pods will have the same IP address inside the pod as they do on the VPC network. another repository. If you provide your own subnet and add NSGs associated with that subnet, you must ensure the security rules in the NSGs allow traffic within the node CIDR range. assigned and how many are available. annotations to your Pod. In this demo I will use Flannel for the sake of simplicity. Calico provides a scalable networking solution for connecting containers, VMs, or bare metal. model, Kubernetes also requires the container runtimes to provide a loopback interface lo, which elastic network interface itself. If you've set custom If your cluster isn't in This will deploy an istio-cni-node DaemonSet into the cluster, which installs the Istio CNI plugin binary to each node and sets up the necessary configuration for the plugin. the AWS Region that your cluster is in and then run the modified command to the default settings of the Amazon EKS add-on, creation might fail. specific configuration to support kube-proxy. If you want to enable hostPort support, you must specify portMappings capability in your cni-bin-dir and network-plugin command-line parameters.
