Types

type Args

type Args struct {
	Command       string
	ContainerID   string
	NetNS         string
	PluginArgs    [][2]string
	PluginArgsStr string
	IfName        string
	Path          string
}

func (*Args) AsEnv

func (args *Args) AsEnv() []string

type CNIArgs

type CNIArgs interface {
	// For use with os/exec; i.e., return nil to inherit the
	// environment from this process
	AsEnv() []string
}

func ArgsFromEnv

func ArgsFromEnv() CNIArgs

type PluginExec

type PluginExec struct {
	RawExec interface {
		ExecPlugin(pluginPath string, stdinData []byte, environ []string) ([]byte, error)
	}
	VersionDecoder interface {
		Decode(jsonBytes []byte) (version.PluginInfo, error)
	}
}

func (*PluginExec) GetVersionInfo

func (e *PluginExec) GetVersionInfo(pluginPath string) (version.PluginInfo, error)

GetVersionInfo returns the version information available about the plugin. For recent-enough plugins, it uses the information returned by the VERSION command. For older plugins which do not recognize that command, it reports version 0.1.0

func (*PluginExec) WithResult

func (e *PluginExec) WithResult(pluginPath string, netconf []byte, args CNIArgs) (types.Result, error)

func (*PluginExec) WithoutResult

func (e *PluginExec) WithoutResult(pluginPath string, netconf []byte, args CNIArgs) error

type RawExec

type RawExec struct {
	Stderr io.Writer
}

func (*RawExec) ExecPlugin

func (e *RawExec) ExecPlugin(pluginPath string, stdinData []byte, environ []string) ([]byte, error)
