cni

README

This package abstracts CNI from libpod. It implements the ContainerNetwork interface defined in libpod/network/types/network.go for the CNI backend.

Testing

Run the tests with:

go test -v -mod=vendor -cover ./libpod/network/cni/

Run the tests as root to also test setup/teardown. This will execute CNI and therefore the cni plugins have to be installed.

Functions

func CNIResultToStatus

func CNIResultToStatus(res cnitypes.Result) (types.StatusBlock, error)

CNIResultToStatus convert the cni result to status block nolint:golint,revive

func NewCNINetworkInterface

func NewCNINetworkInterface(conf *InitConfig) (types.ContainerNetwork, error)

NewCNINetworkInterface creates the ContainerNetwork interface for the CNI backend. Note: The networks are not loaded from disk until a method is called.
