A Go client that interacts with the Vultr Metadata.
go get -u github.com/vultr/metadata
Currently, there is only one available call Metadata() which will retrieve your entire metadata from your instance. If you want to retrieve a specific of your metadata you can do so by calling the corresponding exported field on the metadata struct.
c := metadata.NewClient()
meta, err := c.Metadata()
if err != nil {
fmt.Println(err)
}
fmt.Println(meta)
fmt.Println(meta.InstanceID) // will print your instance-id
