Types

type DefaultRemoteExecutor 

type DefaultRemoteExecutor struct{}

DefaultRemoteExecutor is the standard implementation of remote command execution

func (*DefaultRemoteExecutor) Execute 

func (*DefaultRemoteExecutor) Execute(method string, url *url.URL, config *restclient.Config, stdin io.Reader, stdout, stderr io.Writer, tty bool) error

type NameGenerator 

type NameGenerator interface {
	// GenerateName generates a valid name from the base name, adding a random suffix to the
	// the base. If base is valid, the returned name must also be valid. The generator is
	// responsible for knowing the maximum valid name length.
	GenerateName(base string) string
}

NameGenerator generates names for objects. Some backends may have more information available to guide selection of new names and this interface hides those details. 

var SimpleNameGenerator NameGenerator = simpleNameGenerator{}

SimpleNameGenerator is a generator that returns the name plus a random suffix of five alphanumerics when a name is requested. The string is guaranteed to not exceed the length of a standard Kubernetes name (63 characters)

type PodExecOptions 

type PodExecOptions struct {
	StreamOptions

	Command []string

	PodName       string
	Namespace     string
	ContainerName string

	Executor RemoteExecutor
	Config   *restclient.Config
}

PodExecOptions declare the arguments accepted by the Exec command

func (*PodExecOptions) Run 

func (p *PodExecOptions) Run() error

Run executes a validated remote execution against a pod.
