Functions

func GetEnvVarRefString

func GetEnvVarRefString(from *corev1.EnvVarSource) string

GetEnvVarRefString returns a text description of whichever field is set within the supplied EnvVarSource argument.

func GetEnvVarRefValue

func GetEnvVarRefValue(kc kubernetes.Interface, ns string, store *ResourceStore, from *corev1.EnvVarSource, obj runtime.Object, c *corev1.Container) (string, error)

GetEnvVarRefValue returns the value referenced by the supplied EnvVarSource given the other supplied information.

func IsEnvironmentArgument

func IsEnvironmentArgument(s string) bool

IsEnvironmentArgument checks whether a string is an environment argument, that is, whether it matches the "anycharacters=anycharacters" pattern.

func IsValidEnvironmentArgument

func IsValidEnvironmentArgument(s string) bool

IsValidEnvironmentArgument checks whether a string is a valid environment argument, that is, whether it matches the "wordcharacters=anycharacters" pattern. Word characters can be letters, numbers, and underscores.

func ParseEnv

func ParseEnv(spec []string, defaultReader io.Reader) ([]v1.EnvVar, []string, error)

ParseEnv parses the elements of the first argument looking for environment variables in key=value form and, if one of those values is "-", it also scans the reader. The same environment variable cannot be both modified and removed in the same command.

func SplitEnvironmentFromResources

func SplitEnvironmentFromResources(args []string) (resources, envArgs []string, ok bool)

SplitEnvironmentFromResources separates resources from environment arguments. Resources must come first. Arguments may have the "DASH-" syntax.

Types

type ResourceStore

type ResourceStore struct {
	SecretStore    map[string]*corev1.Secret
	ConfigMapStore map[string]*corev1.ConfigMap
}

ResourceStore defines a new resource store data structure.

func NewResourceStore

func NewResourceStore() *ResourceStore

NewResourceStore returns a pointer to a new resource store data structure.
