Types

type HyperKube

type HyperKube struct {
	Name string // The executable name, used for help and soft-link invocation
	Long string // A long description of the binary.  It will be world wrapped before output.
	// contains filtered or unexported fields
}

HyperKube represents a single binary that can morph/manage into multiple servers.

func (*HyperKube) AddServer

func (hk *HyperKube) AddServer(s *Server)

AddServer adds a server to the HyperKube object.

func (*HyperKube) FindServer

func (hk *HyperKube) FindServer(name string) (*Server, error)

FindServer will find a specific server named name.

func (*HyperKube) Flags

func (hk *HyperKube) Flags() *pflag.FlagSet

Flags returns a flagset for "global" flags.

func (*HyperKube) MakeSymlinks

func (hk *HyperKube) MakeSymlinks(command string) error

MakeSymlinks will create a symlink for each registered hyperkube server in the local directory.

func (*HyperKube) Out

func (hk *HyperKube) Out() io.Writer

Out returns the io.Writer that is used for all usage/error information

func (*HyperKube) Print

func (hk *HyperKube) Print(i ...interface{})

Print is a convenience method to Print to the defined output

func (*HyperKube) Printf

func (hk *HyperKube) Printf(format string, i ...interface{})

Printf is a convenience method to Printf to the defined output

func (*HyperKube) Println

func (hk *HyperKube) Println(i ...interface{})

Println is a convenience method to Println to the defined output

func (*HyperKube) Run

func (hk *HyperKube) Run(args []string, stopCh <-chan struct{}) error

Run the server. This will pick the appropriate server and run it.

func (*HyperKube) RunToExit

func (hk *HyperKube) RunToExit(args []string)

RunToExit will run the hyperkube and then call os.Exit with an appropriate exit code.

func (*HyperKube) Servers

func (hk *HyperKube) Servers() []Server

Servers returns a list of all of the registered servers

func (*HyperKube) SetOut

func (hk *HyperKube) SetOut(w io.Writer)

SetOut sets the output writer for all usage/error information

func (*HyperKube) Usage

func (hk *HyperKube) Usage()

Usage will write out a summary for all servers that this binary supports.

type Server

type Server struct {
	SimpleUsage     string        // One line description of the server.
	Long            string        // Longer free form description of the server
	Run             serverRunFunc // Run the server.  This is not expected to return.
	AlternativeName string
	RespectsStopCh  bool
	// contains filtered or unexported fields
}

Server describes a server that this binary can morph into.
