func GetDefaultInterfaceIP ¶

func GetDefaultInterfaceIP(ifname, ipAddrOverride string) (string, error)

GetDefaultInterfaceIP determines the appropriate IP address to use for either the server or agent based on configuration parameters passed in as arguments

The server uses this address to inform the agents of the URL they should use to download assets ¶

The agents use this address so that the server knows how to orchestrate tests. (i.e. This agent publishes it's default address, and the server instructs other agents to target it in tests)

func IsShortID ¶

func IsShortID(id string) bool

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 langer prefix, or the full-length Id.
