Functions

func GetKeyField

func GetKeyField(keyString string, v reflect.Value) reflect.Value

GetKeyField is a helper function to receive Values Values that represent a pointer to a struct

func LoadArgs

func LoadArgs(args string, container interface{}) error

LoadArgs parses args from a string in the form "K=V;K2=V2;..."

func ParseCIDR

func ParseCIDR(s string) (*net.IPNet, error)

ParseCIDR takes a string like "10.2.3.1/24" and return IPNet with "10.2.3.1" and /24 mask

func PrintResult

func PrintResult(result Result, version string) error

Types

type CommonArgs

type CommonArgs struct {
	IgnoreUnknown UnmarshallableBool `json:"ignoreunknown,omitempty"`
}

CommonArgs contains the IgnoreUnknown argument and must be embedded by all Arg structs

type DNS

type DNS struct {
	Nameservers []string `json:"nameservers,omitempty"`
	Domain      string   `json:"domain,omitempty"`
	Search      []string `json:"search,omitempty"`
	Options     []string `json:"options,omitempty"`
}

DNS contains values interesting for DNS resolvers

func (*DNS) Copy

func (d *DNS) Copy() *DNS

type Error

type Error struct {
	Code    uint   `json:"code"`
	Msg     string `json:"msg"`
	Details string `json:"details,omitempty"`
}

func NewError

func NewError(code uint, msg, details string) *Error

func (*Error) Error

func (e *Error) Error() string

func (*Error) Print

func (e *Error) Print() error

type IPAM

type IPAM struct {
	Type string `json:"type,omitempty"`
}

type IPNet

type IPNet net.IPNet

like net.IPNet but adds JSON marshalling and unmarshalling

func (IPNet) MarshalJSON

func (n IPNet) MarshalJSON() ([]byte, error)

func (*IPNet) UnmarshalJSON

func (n *IPNet) UnmarshalJSON(data []byte) error

type NetConf

type NetConf struct {
	CNIVersion string `json:"cniVersion,omitempty"`

	Name         string          `json:"name,omitempty"`
	Type         string          `json:"type,omitempty"`
	Capabilities map[string]bool `json:"capabilities,omitempty"`
	IPAM         IPAM            `json:"ipam,omitempty"`
	DNS          DNS             `json:"dns"`

	RawPrevResult map[string]interface{} `json:"prevResult,omitempty"`
	PrevResult    Result                 `json:"-"`
}

NetConf describes a network.

type NetConfList

type NetConfList struct {
	CNIVersion string `json:"cniVersion,omitempty"`

	Name         string     `json:"name,omitempty"`
	DisableCheck bool       `json:"disableCheck,omitempty"`
	Plugins      []*NetConf `json:"plugins,omitempty"`
}

NetConfList describes an ordered list of networks.

type Result

type Result interface {
	// The highest CNI specification result version the result supports
	// without having to convert
	Version() string

	// Returns the result converted into the requested CNI specification
	// result version, or an error if conversion failed
	GetAsVersion(version string) (Result, error)

	// Prints the result in JSON format to stdout
	Print() error

	// Prints the result in JSON format to provided writer
	PrintTo(writer io.Writer) error
}

Result is an interface that provides the result of plugin execution

type Route

type Route struct {
	Dst net.IPNet
	GW  net.IP
}

func (*Route) Copy

func (r *Route) Copy() *Route

func (Route) MarshalJSON

func (r Route) MarshalJSON() ([]byte, error)

func (*Route) String

func (r *Route) String() string

func (*Route) UnmarshalJSON

func (r *Route) UnmarshalJSON(data []byte) error

type UnmarshalableArgsError

type UnmarshalableArgsError struct {
	// contains filtered or unexported fields
}

UnmarshalableArgsError is used to indicate error unmarshalling args from the args-string in the form "K=V;K2=V2;..."

type UnmarshallableBool

type UnmarshallableBool bool

UnmarshallableBool typedef for builtin bool because builtin type's methods can't be declared

func (*UnmarshallableBool) UnmarshalText

func (b *UnmarshallableBool) UnmarshalText(data []byte) error

UnmarshalText implements the encoding.TextUnmarshaler interface. Returns boolean true if the string is "1" or "[Tt]rue" Returns boolean false if the string is "0" or "[Ff]alse"

type UnmarshallableString

type UnmarshallableString string

UnmarshallableString typedef for builtin string

func (*UnmarshallableString) UnmarshalText

func (s *UnmarshallableString) UnmarshalText(data []byte) error

UnmarshalText implements the encoding.TextUnmarshaler interface. Returns the string
