Functions

func AddIgnoreUnknownArgs

func AddIgnoreUnknownArgs() error

AddIgnoreUnknownArgs appends the 'IgnoreUnknown=1' option to CNI_ARGS before calling the IPAM plugin. Otherwise, it will complain about the Kubernetes arguments. See https://github.com/kubernetes/kubernetes/pull/24983

func ConfigureLogging

func ConfigureLogging(logLevel string)

Set up logging for both Calico and libcalico usng the provided log level,

func CreateClient

func CreateClient(conf NetConf) (*client.Client, error)

func CreateContextLogger

func CreateContextLogger(workload string) *log.Entry

Create a logger which always includes common fields

func CreateResultFromEndpoint

func CreateResultFromEndpoint(ep *api.WorkloadEndpoint) (*types.Result, error)

func DoNetworking

func DoNetworking(args *skel.CmdArgs, conf NetConf, res *types.Result, logger *log.Entry, desiredVethName string) (hostVethName, contVethMAC string, err error)

DoNetworking performs the networking for the given config and IPAM result

func GetIdentifiers

func GetIdentifiers(args *skel.CmdArgs) (workloadID string, orchestratorID string, err error)

func PopulateEndpointNets

func PopulateEndpointNets(endpoint *api.WorkloadEndpoint, result *types.Result) error

func ReleaseIPAllocation

func ReleaseIPAllocation(logger *log.Entry, ipamType string, stdinData []byte)

ReleaseIPAM is called to cleanup IPAM allocations if something goes wrong during CNI ADD execution.

func ValidateNetworkName

func ValidateNetworkName(name string) error

ValidateNetworkName checks that the network name meets felix's expectations

NetConf stores the common network config for Calico CNI plugin

type NetworkInfo

type NetworkInfo struct {
	Name   string `json:"name"`
	Labels struct {
		Labels []struct {
			Key   string `json:"key"`
			Value string `json:"value"`
		} `json:"labels,omitempty"`
	} `json:"labels,omitempty"`
}

type Policy

type Policy struct {
	PolicyType              string `json:"type"`
