Types

type Config

type Config struct {
	LogLevel string `json:"LogLevel,omitempty"`
	LogFile  string `json:"LogFile,omitempty"`
}

type K8sArgs

type K8sArgs struct {
	types.CommonArgs
	IP                         net.IP
	K8S_POD_NAME               types.UnmarshallableString // nolint: revive, stylecheck
	K8S_POD_NAMESPACE          types.UnmarshallableString // nolint: revive, stylecheck
	K8S_POD_INFRA_CONTAINER_ID types.UnmarshallableString // nolint: revive, stylecheck
}

K8sArgs is the valid CNI_ARGS used for Kubernetes The field names need to match exact keys in kubelet args for unmarshalling

type Kubernetes

type Kubernetes struct {
	K8sAPIRoot           string   `json:"k8s_api_root"`
	Kubeconfig           string   `json:"kubeconfig"`
	InterceptRuleMgrType string   `json:"intercept_type"`
	NodeName             string   `json:"node_name"`
	ExcludeNamespaces    []string `json:"exclude_namespaces"`
	CNIBinDir            string   `json:"cni_bin_dir"`
}

Kubernetes a K8s specific struct to hold config

type PodNetConf

type PodNetConf struct {
	types.NetConf // You may wish to not nest this type
	RuntimeConfig *struct {
	} `json:"runtimeConfig"`

	// This is the previous result, when called in the context of a chained
	// plugin. Because this plugin supports multiple versions, we'll have to
	// parse this in two passes. If your plugin is not chained, this can be
	// removed (though you may wish to error if a non-chainable plugin is
	// chained.
	// If you need to modify the result before returning it, you will need
	// to actually convert it to a concrete versioned struct.
	RawPrevResult *map[string]any `json:"prevResult"`
	PrevResult    *cniv1.Result   `json:"-"`

	// Add plugin-specific flags here
	LogLevel        string     `json:"log_level"`
	LogUDSAddress   string     `json:"log_uds_address"`
	Kubernetes      Kubernetes `json:"kubernetes"`
	HostNSEnterExec bool       `json:"hostNSEnterExec"`
}

PodNetConf is whatever you expect your configuration json to be. This is whatever is passed in on stdin. Your plugin may wish to expose its functionality via runtime args, see CONVENTIONS.md in the CNI spec.
