Types

type ConfLoader

type ConfLoader interface {
	// LoadConf loads configuration from CNI CmdArgs
	LoadConf(args *skel.CmdArgs) (*NetConf, error)
}

ConfLoader loads CNI configuration

func NewConfLoader

func NewConfLoader() ConfLoader

type IPAMArgs

type IPAMArgs struct {
	IPs                    []string `json:"ips"`
	PoolNames              []string `json:"poolNames"`
	PoolType               string   `json:"poolType"`
	AllocateDefaultGateway bool     `json:"allocateDefaultGateway"`
}

IPAMArgs holds arguments from stdin args["cni"]

type IPAMConf

type IPAMConf struct {
	types.IPAM

	// PoolName is the name of the pool to be used to allocate IP
	PoolName string `json:"poolName,omitempty"`
	// PoolType is the type of the pool which is referred by the PoolName,
	// supported values: ippool, cidrpool
	PoolType string `json:"poolType,omitempty"`
	// Address of the NVIDIA-ipam DaemonSocket
	DaemonSocket             string `json:"daemonSocket,omitempty"`

	// internal representation of the requested features
	Features struct {
		// request to allocate pool's default gateway as
		// interface IP address for the container
		AllocateDefaultGateway bool
	} `json:"-"`
}

IPAMConf is the configuration supported by our CNI plugin

type IPAMEnvArgs

type IPAMEnvArgs struct {
	types.CommonArgs
	IP                types.UnmarshallableString
	K8S_POD_NAME      types.UnmarshallableString //nolint
	K8S_POD_NAMESPACE types.UnmarshallableString //nolint
	K8S_POD_UID       types.UnmarshallableString //nolint
}

IPAMEnvArgs holds arguments from CNI_ARGS env variable

type NetConf

type NetConf struct {
	Name          string    `json:"name"`
	CNIVersion    string    `json:"cniVersion"`
	IPAM          *IPAMConf `json:"ipam"`
	DeviceID      string    `json:"deviceID"`

		IPs []string `json:"ips,omitempty"`
	} `json:"runtimeConfig,omitempty"`
	Args *struct {
		ArgsCNI *IPAMArgs `json:"cni"`
