Functions

func AddPrinterFlags

func AddPrinterFlags(cmd *cobra.Command)

func CompareNamespace

func CompareNamespace(defaultNamespace, namespace string) error

CompareNamespace 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 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 GetFilesFromDir

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

Return a list of file names of a certain type within a given directory. TODO: replace with resource.Builder

func GetFlagBool

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

func GetFlagBoolPtr

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

Returns nil if the flag wasn't set.

func GetFlagDuration

func GetFlagDuration(cmd *cobra.Command, flag string) time.Duration

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 Merge

func Merge(dst runtime.Object, fragment, kind string) error

func OutputVersion

func OutputVersion(cmd *cobra.Command, defaultVersion string) string

OutputVersion returns the preferred output version for generic content (JSON, YAML, or templates)

func PrinterForCommand

func PrinterForCommand(cmd *cobra.Command) (kubectl.ResourcePrinter, bool, error)

PrinterForCommand returns the default printer for this command. Requires that printer flags have been added to cmd (see AddPrinterFlags).

func ReadConfigData

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

ReadConfigData reads the bytes from the specified filesytem or network location or from stdin if location == "-". TODO: replace with resource.Builder

func ReadConfigDataFromLocation

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

TODO: replace with resource.Builder

func ResourceFromArgs

func ResourceFromArgs(cmd *cobra.Command, args []string, mapper meta.RESTMapper, cmdNamespace string) (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, cmdNamespace, cmdVersion string) (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(filename string, typer runtime.ObjectTyper, mapper meta.RESTMapper, schema validation.Schema, cmdVersion string) (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, cmdNamespace, cmdVersion string) (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 ResourcesFromArgsOrFile

func ResourcesFromArgsOrFile(
	cmd *cobra.Command,
	args []string,
	filename, selector string,
	typer runtime.ObjectTyper,
	mapper meta.RESTMapper,
	clientBuilder func(cmd *cobra.Command, mapping *meta.RESTMapping) (resource.RESTClient, error),
	schema validation.Schema,
	requireNames bool,
	cmdNamespace,
	cmdVersion string,
) resource.Visitor

ResourcesFromArgsOrFile computes a list of Resources by extracting info from filename or args. It will handle label selectors provided.

func SplitResourceArgument

func SplitResourceArgument(arg string) []string
