CompareNamespaceFromFile returns an error if the namespace the user has provided on the CLI or via the default namespace file does not match the namespace of an input file. This prevents a user from unintentionally updating the wrong namespace.

func DataToObjects 

func DataToObjects(m meta.RESTMapper, t runtime.ObjectTyper, data []byte) (result []runtime.Object, errors []error)

DataToObjects converts the raw JSON data into API objects

func FirstNonEmptyString 

func FirstNonEmptyString(args ...string) string

Returns the first non-empty string out of the ones provided. If all strings are empty, returns an empty string.

func GetExplicitKubeNamespace added in v0.7.0 

func GetExplicitKubeNamespace(cmd *cobra.Command) (string, bool)

GetExplicitKubeNamespace returns the value of the namespace a user explicitly provided on the command line, or false if no such namespace was specified.

func GetFilesFromDir 

func GetFilesFromDir(directory string, fileType string) []string

Return a list of file names of a certain type within a given directory.

func GetFlagBool

func GetFlagBoolPtr 

func GetFlagBoolPtr(cmd *cobra.Command, flag string) *bool

Returns nil if the flag wasn't set.

func GetFlagInt 

func GetFlagInt(cmd *cobra.Command, flag string) int

Assumes the flag has a default value.

func GetFlagString 

func GetFlagString(cmd *cobra.Command, flag string) string

func GetKubeNamespace added in v0.7.0 

func GetKubeNamespace(cmd *cobra.Command) string

func ReadConfigData 

func ReadConfigData(location string) ([]byte, error)

ReadConfigData reads the bytes from the specified filesytem or network location or from stdin if location == "-".

func ReadConfigDataFromLocation 

func ReadConfigDataFromLocation(location string) ([]byte, error)

func ResourceFromArgs 

func ResourceFromArgs(cmd *cobra.Command, args []string, mapper meta.RESTMapper) (mapping *meta.RESTMapping, namespace, name string)

ResourceFromArgs expects two arguments with a given type, and extracts the fields necessary to uniquely locate a resource. Displays a usageError if that contract is not satisfied, or a generic error if any other problems occur.

func ResourceFromArgsOrFile 

func ResourceFromArgsOrFile(cmd *cobra.Command, args []string, filename string, typer runtime.ObjectTyper, mapper meta.RESTMapper, schema validation.Schema) (mapping *meta.RESTMapping, namespace, name string)

ResourceFromArgsOrFile expects two arguments or a valid file with a given type, and extracts the fields necessary to uniquely locate a resource. Displays a usageError if that contract is not satisfied, or a generic error if any other problems occur.

func ResourceFromFile 

func ResourceFromFile(cmd *cobra.Command, filename string, typer runtime.ObjectTyper, mapper meta.RESTMapper, schema validation.Schema) (mapping *meta.RESTMapping, namespace, name string, data []byte)

ResourceFromFile retrieves the name and namespace from a valid file. If the file does not resolve to a known type an error is returned. The returned mapping can be used to determine the correct REST endpoint to modify this resource with.

func ResourceOrTypeFromArgs 

func ResourceOrTypeFromArgs(cmd *cobra.Command, args []string, mapper meta.RESTMapper) (mapping *meta.RESTMapping, namespace, name string)

ResourceFromArgs expects two arguments with a given type, and extracts the fields necessary to uniquely locate a resource. Displays a usageError if that contract is not satisfied, or a generic error if any other problems occur.

func SplitResourceArgument added in v0.8.0 

func SplitResourceArgument(arg string) []string

Types

type Factory 

type Factory struct {
	ClientBuilder clientcmd.Builder
	Mapper        meta.RESTMapper
	Typer         runtime.ObjectTyper
	Client        func(cmd *cobra.Command, mapping *meta.RESTMapping) (kubectl.RESTClient, error)
	Describer     func(cmd *cobra.Command, mapping *meta.RESTMapping) (kubectl.Describer, error)
	Printer       func(cmd *cobra.Command, mapping *meta.RESTMapping, noHeaders bool) (kubectl.ResourcePrinter, error)
	Validator     func(*cobra.Command) (validation.Schema, error)
}

Factory provides abstractions that allow the Kubectl command to be extended across multiple types of resources and different API sets.

	Namespace string
	Selector  labels.Selector
}

ResourceSelector is a facade for all the resources fetched via label selector

func NewResourceSelector added in v0.8.0
