Read more information about UE device configuration in the Web UI from my previous post. It achieves this by connecting your containers to a vRouter, which then routes traffic directly over the L3 network. A Container Runtime, in the networking context, is a daemon on a node configured to provide CRI plugin offered by the CNI plugin team or use your own plugin with portMapping functionality. Amazon CloudWatch console. By using this CNI plugin your Kubernetes pods will have the same IP address inside the pod as they do on the VPC network. Asking for help, clarification, or responding to other answers. Installing container runtime Confirm that the latest version of the add-on for your cluster's Kubernetes version The --resolve-conflicts Each network attachment created by Multus will be in addition to this default network interface. These operations include: To monitor the 5G core services on Kubernetes I have used Prometheus. It also handles all the necessary IP routing, security policy rules, and distribution of routes across a cluster of nodes. The following metrics are collected for your cluster and exported to CloudWatch: The maximum number of network interfaces that the cluster can support, The number of network interfaces have been allocated to pods, The number of IP addresses currently assigned to pods, The total and maximum numbers of IP addresses available. CNI plugins: conform to the specification of the container network interface (CNI) and are created with the interoperability in mind. self-managed type of this add-on, see Updating the self-managed us-west-2, then replace add-on creates elastic network The add-on creates elastic network interfaces (network interfaces) and attaches them to your Amazon EC2 nodes. update to the same version) as your Amazon VPC CNI plugin for Kubernetes, run the following command Staging Ground Beta 1 Recap, and Reviewers needed for Beta 2, kibana in the kebernets cluster doesn't work, Kubernetes 1.6.2 flannel configuration in centos 7, flannel pods in CrashLoopBackoff Error in kubernetes, Kubernetes HA: Flannel throws SubnetManager error, Kube-Flannel cant get CIDR although PodCIDR available on node, How to fix Flannel CNI plugin.

CNI supports plugin-based functionality to simplify networking in Kubernetes. The Kubernetes project recommends using a plugin that is Install Kubernetes with the container runtime supporting CNI and kubelet configured with the main CNI.
