Why do we need CNI?
Use-cases: If you are working on latency-sensitive applications, the AWS-CNI plugin allows accepting traffic directly to your pods. AWS-CNI plugin creates a virtual network interface on the host instance and creates a network route directly to the pods. This property can help decrease the network latency.
What is CNI in container?
What is CNI? 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).
How does CNI work in Kubernetes?
The CNI allocates AWS Elastic Networking Interfaces (ENIs) to each Kubernetes node and using the secondary IP range from each ENI for pods on the node. The CNI includes controls for pre-allocation of ENIs and IP addresses for fast pod startup times and enables large clusters of up to 2,000 nodes.
Which is the best CNI for Kubernetes?
Calico has emerged as one of the most popular CNI plugins for Kubernetes cluster networking. The project has earned a reputation for being reliable, flexible, and supporting highly performant networks for Kubernetes clusters.

How do I check my CNI in Kubernetes?
In addition to this answer you can also check which one you have by running command ls /etc/cni/net. d . It will show your cni's conf.
What Kubernetes is used for?
Kubernetes, often abbreviated as “K8s”, orchestrates containerized applications to run on a cluster of hosts. The K8s system automates the deployment and management of cloud native applications using on-premises infrastructure or public cloud platforms.
Which networking model is used by Kubernetes?
Kubernetes follows an “IP-per-pod” model where each pod get assigned an IP address and all containers in a single pod share the same network namespaces and IP address.
Is kube proxy a CNI?
Show activity on this post. Kube-proxy control the K8s network communication,and the network is based on CNI plugin.
What is POD in Kubernetes?
A pod is the smallest execution unit in Kubernetes. A pod encapsulates one or more applications. Pods are ephemeral by nature, if a pod (or the node it executes on) fails, Kubernetes can automatically create a new replica of that pod to continue operations.
What is cluster IP in Kubernetes?
The ClusterIP provides a load-balanced IP address. One or more pods that match a label selector can forward traffic to the IP address. The ClusterIP service must define one or more ports to listen on with target ports to forward TCP/UDP traffic to containers.
What is helm in Kubernetes?
Helm is a Kubernetes deployment tool for automating creation, packaging, configuration, and deployment of applications and services to Kubernetes clusters. Kubernetes is a powerful container-orchestration system for application deployment.
What is CNI in Kubernetes medium?
What Is A CNI? A CNI is a standard network implementation interface in Kubernetes. Kubelet calls different network plug-ins through CNIs to implement different network configuration methods. A series of CNIs are implemented by plug-ins such as Calico, Flannel, Terway, Weave Net, and Contiv.
What is CNI in OpenShift?
Overview. The Container Network Interface (CNI) badge is a specialization within Red Hat OpenShift certification available to networking products that integrate with OpenShift using a CNI plug-in. To be eligible for this badge, the CNI plug-in must be deployed and managed through an Operator.
What is OCI and CRI?
The Open Container Initiative (OCI) provides a set of industry practices that standardize the use of container image formats and container runtimes. CRI only supports container runtimes that are compliant with the Open Container Initiative.
What is CRI in Kubernetes?
The CRI is a plugin interface which enables the kubelet to use a wide variety of container runtimes, without having a need to recompile the cluster components. You need a working container runtime on each Node in your cluster, so that the kubelet can launch Pods and their containers.
What does CNI stand for in networking?
CNI stands for Container Networking Interface and it’s goal is to create a generic plugin-based networking solution for containers. CNI is defined by a spec (read it now, its not very long) that has some interesting language in it. Here are a couple of points I found interesting during my first read through…
How are CNI network definitions stored?
Network definitions for CNI are stored as JSON files. The network definitions are streamed to the plugin through STDIN. That is – there are no configuration files sitting on the host for the network configuration. Other arguments are passed to the plugin via environmental variables.
What is a CNI plugin?
The CNI plugin is responsible wiring up the container. That is – it needs to do all the work to get the container on the network. In Docker, this would include connecting the container network namespace back to the host somehow.
What is CNI_IFNAME=eth12?
CNI_IFNAME=eth12 – The name of the interface we wish to use on the container side of the connection
Can you use CNI with Docker?
So the next question might be, can I use CNI with Docker? The answer is yes, but not as an all in one solution. Docker has it’s own network plugin system called CNM. CNM allows plugins to interact directly with Docker. A CNM plugin can be registered to Docker and used directly from it. That is, you can use Docker to run containers and directly assign their network to the CNM registered plugin. This works well, but because Docker has CNM, they dont directly integrate with CNI (as far as I can tell). That does not mean however, that you can’t use CNI with Docker. Recall from the sixth bullet above that the plugin is responsible for wiring up the container. So it seems possible that Docker could be the container runtime – but not handle the networking end of things (more on this in a future post).
What is CNI?
CNI ( Container Network Interface ), a Cloud Native Computing Foundation project, consists of a specification and libraries for writing plugins to configure network interfaces in Linux containers, along with a number of supported plugins. CNI concerns itself only with network connectivity of containers and removing allocated resources when the container is deleted. Because of this focus, CNI has a wide range of support and the specification is simple to implement.
What is CNI in Linux?

Why develop CNI?
We believe that many container runtimes and orchestrators will seek to solve the same problem of making the network layer pluggable.
What might CNI do in the future?
However, in the future CNI might want to branch out into other directions:
What is NSX plugin?
VMware NSX – a CNI plugin that enables automated NSX L2/L3 networking and L4/L7 Load Balancing; network isolation at the pod, node, and cluster level; and zero-trust security policy for your Kubernetes cluster.
What is CNI in containers?
CNI concerns itself only with network connectivity of containers and removing allocated resources when the container is deleted. Because of this focus, CNI has a wide range of support and the specification is simple to implement.
What is CNI spec?
The CNI spec is language agnostic. To use the Go language libraries in this repository, you'll need a recent version of Go. You can find the Go versions covered by our automated tests in .travis.yaml.
Main Goals
The official documentation outlines a number of requirements that any CNI plugin implementation should support. Rephrasing it in a slightly different way, a CNI plugin must provide at least the following two things:
Secondary Goals
In addition to the base functionality described above, there’s always a need to do things like:
Operation
Contrary to the typical network plugin design approach that includes a long-lived stateful daemon, CNI Specification defines an interface – a set of input/output parameters that a CNI binary is expected to ingest/produce. This makes for a very clean design that is also very easy to swap and upgrade.
What to know more?
To learn more about CNI, you can search for the “Kubernetes and the CNI: Where We Are and What’s Next”, which I cannot recommend highly enough. It is what’s shaped my current view of the CNI and heavily inspired the current article. Some other links I can recommend:
