func Init

func Init()

Init looks up each registered command-line flag in the Google Compute Engine instance metadata server to see if a value was specified in the instance creation request. If so, Init sets the flag to that value.

For example, if the instance request said --metadata x=y and there is a flag named x, metaflag.Init causes the flag x to be set to y.

The expected use is:

metadata.Init()
flag.Parse()

to allow the instance creation request to set default flag values but still allow the command line to override those.
