Functions

func ByteArrayToAlphaNum

func ByteArrayToAlphaNum(bytes []byte) string

func ConfigGetInt32

func ConfigGetInt32(config map[string]string, key string, defaultValue int32) int32

ConfigGetInt32 extracts the int32 value from the entry with the given key

Returns `defaultValue` if either the entry does not exist, or is not a numeric value.

func Converter

func Converter(labels map[string]string) *string

func GetBoolean

func GetBoolean(labels map[string]string, key string) bool

func GetEnv

func GetEnv() map[string]string

func GetEnvValueCaseInsensitive

func GetEnvValueCaseInsensitive(caseInsensitiveKey string) string

func GetOptional

func GetOptional(labels map[string]string, key string) *string

func IsShared

func IsShared(labels map[string]string) bool

IsShared determines whether a volume is shared between replicas

func IsSingleton

func IsSingleton(labels map[string]string) bool

IsSingleton determine whether a resource (according to its labels) should be treated as a singleton.

func IsTruthy

func IsTruthy(s string) bool

IsTruthy determines whether the given string is a representation of a "true" state.

Concretly, it currently tests for "true", "yes" or "1", ignoring character cases.

func Sanitize

func Sanitize(str string) string

Sanitize ensures a string only contains alphanumeric characters, and starts with a letter

func SanitizeWithMinLength

func SanitizeWithMinLength(str string, minLength int) string

SanitizeWithMinLength applies `Sanitize`, and then ensures the result is at least `minLength` characters long.

If the resulting string is too short, a stable generated value of `minLength` characters will be returned.

func ServiceAccountName

func ServiceAccountName(labels map[string]string) string

func StorageClass

func StorageClass(labels map[string]string) *string

StorageClass determines a storage class from a set of labels

func StorageSize

func StorageSize(labels map[string]string, fallback string) resource.Quantity

StorageSize determines the requested storage size for a volume, or a fallback value.

func StorageSizeRaw

func StorageSizeRaw(labels map[string]string) *string

func SubConfig

func SubConfig(config map[string]string, prefix string, defaultKey string) map[string]string

SubConfig extracts the keys that start with a given prefix from a given config map

If there is a key that is EQUAL to the prefix, the entry identified by `defaultKey` will be updated.

If there is a key that is equal to the prefix, AND an entry corresponding to `defaultKey`, the behavior is undefined!
