The Specification document proposes a generic plugin-based networking solution for application containers on Linux, the Container Networking Interface, or CNI. It is derived from the rkt Networking Proposal, which aimed to satisfy many of the design considerations for networking in rkt .
Version
The latest CNI spec version 0.4.0.
Note that this is independent from the version of the CNI library and plugins in this repository (e.g. the versions of releases ).
Released versions
Released versions of the spec are available as Git tags.
