# Container Networking Interface (CNI)
|
||
|
|
|
||
|
|
**Project Name:** cni
|
||
|
|
|
||
|
|
**Description**
|
||
|
|
|
||
|
|
The CNI (Container Network Interface) 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. CNI consists of 3 separate comonents:
|
||
|
|
|
||
|
|
* CNI Specification: defines an straightforward API between runtimes and network plugins for container network setup/teardown. No more, no less.
|
||
|
|
* Plugins: provide network setup for a variety of use-cases and serve as reference examples of plugins conforming to the CNI specification
|
||
|
|
* Library: provide a Go implementation of the CNI specification that runtimes can use to more easily consume CNI
|
||
|
|
|
||
|
|
NOTE: CNI Specification is independently versioned from the CNI library and plugins in the repository (e.g. the versions of releases). The plugins are being pulled out into a separate repository

|
**Statement on alignment with CNCF mission**:
|
||
|
|
|
||
|
|
CNI defines initial guidelines for a network interface specification focused on
|
||
|
|
connectivity and portability of cloud native application patterns.
|
||
|
|
It is already supported by many cloud native and container runtimes discussed
