ConvertToDNS1123SubdomainCompatibleString converts a string that doesn't conform to the definition of a subdomain in DNS (RFC 1123) to a string that conforms. It doesn't do well on labels (separated by dots) starting or ending with hyphens.

func CopyMap ¶

func CopyMap(o map[string]string) (r map[string]string)

func SanitizeLabelValue ¶ added in v2.0.43

func SanitizeLabelValue(value string) string

SanitizeLabelValue coerces an arbitrary string into a valid Kubernetes label value: at most 63 characters, made up of alphanumerics, dots, dashes and underscores, and beginning and ending with an alphanumeric character. An empty input stays empty so callers can decide whether to stamp the label at all.

func UnionMaps ¶

func UnionMaps(maps ...map[string]string) map[string]string

This function unions a list of maps (each can be nil or populated) by allocating a new map. Conflicting keys will always defer to the later input map's corresponding value.
