func GetEnvVarRefString Uses

func GetEnvVarRefString(from *corev1.EnvVarSource) string

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

func GetEnvVarRefValue Uses

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 Uses

func IsEnvironmentArgument(s string) bool

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

Code:

test := "returnsfalse"
fmt.Println(IsEnvironmentArgument(test))

Output:

false

Code:

test := "returns=true"
fmt.Println(IsEnvironmentArgument(test))

Output:

true

func IsValidEnvironmentArgument Uses

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.

Code:

test := "not$word^characters=test"
fmt.Println(IsValidEnvironmentArgument(test))

Output:

false

Code:

test := "wordcharacters=true"
fmt.Println(IsValidEnvironmentArgument(test))

Output:

true

func ParseEnv Uses

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.

Code:

var r io.Reader
bad := []string{"This not in the key=value format."}
fmt.Println(ParseEnv(bad, r))

Output:

[] [] environment variables must be of the form key=value and can only contain letters, numbers, and underscores

Code:

r := strings.NewReader("FROM=READER")
ss := []string{"ENV=VARIABLE", "AND=ANOTHER", "REMOVE-", "-"}
fmt.Println(ParseEnv(ss, r))

Output:

[{ENV VARIABLE nil} {AND ANOTHER nil} {FROM READER nil}] [REMOVE] <nil>

func SplitEnvironmentFromResources Uses

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.

Code:

args := []string{`resource`, "ENV\\=ARG", `ONE\=MORE`, `DASH-`}
fmt.Println(SplitEnvironmentFromResources(args))

Output:

[resource] [ENV\=ARG ONE\=MORE DASH-] true

type ResourceStore Uses

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

ResourceStore defines a new resource store data structure.

func NewResourceStore Uses

func NewResourceStore() *ResourceStore

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