Functions

func NewCmdGet 

func NewCmdGet(parent string, f cmdutil.Factory, streams genericclioptions.IOStreams) *cobra.Command

NewCmdGet creates a command object for the generic "get" action, which retrieves one or more resources from a server.

func RelaxedJSONPathExpression added in v1.13.0 

func RelaxedJSONPathExpression(pathExpression string) (string, error)

RelaxedJSONPathExpression attempts to be flexible with JSONPath expressions, it accepts:

  • metadata.name (no leading '.' or curly braces '{...}'
  • {metadata.name} (no leading '.')
  • .metadata.name (no curly braces '{...}')
  • {.metadata.name} (complete expression)

And transforms them all into a valid jsonpath expression: 

{.metadata.name}

Types

type Column added in v1.13.0 

type Column struct {
	// The header to print above the column, general style is ALL_CAPS
