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.

	SecretStore    map[string]*corev1.Secret
	ConfigMapStore map[string]*corev1.ConfigMap
}
