Variables ¶

var All = PluginSupports("0.1.0", "0.2.0", "0.3.0", "0.3.1")

var Legacy = PluginSupports("0.1.0", "0.2.0")

Legacy PluginInfo describes a plugin that is backwards compatible with the CNI spec version 0.1.0. In particular, a runtime compiled against the 0.1.0 library ought to work correctly with a plugin that reports support for Legacy versions.

Any future CNI spec versions which meet this definition should be added to this list.

Functions ¶

func Current ¶

func Current() string

Current reports the version of the CNI spec implemented by this library

func NewResult ¶

func NewResult(version string, resultBytes []byte) (types.Result, error)

Finds a Result object matching the requested version (if any) and asks that object to parse the plugin result, returning an error if parsing failed.

Types ¶

type ConfigDecoder ¶

type ConfigDecoder struct{}

ConfigDecoder can decode the CNI version available in network config data

func (*ConfigDecoder) Decode ¶

func (*ConfigDecoder) Decode(jsonBytes []byte) (string, error)

type ErrorIncompatible ¶

type ErrorIncompatible struct {
	Config    string
	Supported []string
}

func (*ErrorIncompatible) Details ¶

func (e *ErrorIncompatible) Details() string

func (*ErrorIncompatible) Error ¶

func (e *ErrorIncompatible) Error() string

type PluginDecoder ¶

type PluginDecoder struct{}

PluginDecoder can decode the response returned by a plugin's VERSION command

func (*PluginDecoder) Decode ¶

func (*PluginDecoder) Decode(jsonBytes []byte) (PluginInfo, error)

type PluginInfo ¶

type PluginInfo interface {
	// SupportedVersions returns one or more CNI spec versions that the plugin
	// supports.  If input is provided in one of these versions, then the plugin
	// promises to use the same CNI version in its response
	SupportedVersions() []string

	// Encode writes this CNI version information as JSON to the given Writer
	Encode(io.Writer) error
}

PluginInfo reports information about CNI versioning

func PluginSupports ¶

func PluginSupports(supportedVersions ...string) PluginInfo

PluginSupports returns a new PluginInfo that will report the given versions as supported

type Reconciler ¶

type Reconciler struct{}

func (*Reconciler) Check ¶

func (r *Reconciler) Check(configVersion string, pluginInfo PluginInfo) *ErrorIncompatible

func (*Reconciler) CheckRaw ¶

func (*Reconciler) CheckRaw(configVersion string, supportedVersions []string) *ErrorIncompatible
