func PickFreePort ¶ added in v0.14.11

func PickFreePort(minPort, maxPort int) (int, error)

PickFreePort returns a TCP port in [min,max] that's not in use on the 127.0.0.1 interface. Note that there's a small chance of a race condition when a port is considered free at the time of the call, but not free when something tries to use it. This is good enough for dev and test code though.
