Functions ¶

func GenerateRandomID ¶

func GenerateRandomID() string

GenerateRandomID returns a unique, 64-character ID consisting of a-z, 0-9. It guarantees that the ID, when truncated (TruncateID) does not consist of numbers only, so that the truncated ID can be used as hostname for containers.

func TruncateID ¶

func TruncateID(id string) string

TruncateID returns a shorthand version of a string identifier for convenience. A collision with other shorthands is very unlikely, but possible. In case of a collision a lookup with TruncIndex.Get() will fail, and the caller will need to use a longer prefix, or the full-length Id.
