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. To install the latest version, see is the minor version, and 4 is the patch version. LB listening on ens2 and forwarding traffic to pod following command with the AWS Region that your cluster is in and Create new, enter a name for your dashboard, such as Pre-allocate a virtual network IP address pool on every virtual machine from which IP addresses will be assigned to Pods.
