# Go bindings for Rancher-metadata
This library is incomplete, but implements a variety of calls against [rancher-metadata](https://github.com/rancher/rancher-metadata) service
#Example usage
```go
package main
import (
"time"
"github.com/rancher/go-rancher-metadata/metadata"
"github.com/sirupsen/logrus"
)
const (
metadataUrl = "http://rancher-metadata/2015-12-19"
)
func main() {
m := metadata.NewClient(metadataUrl)
version := "init"
for {
newVersion, err := m.GetVersion()
if err != nil {
logrus.Errorf("Error reading metadata version: %v", err)
} else if version == newVersion {
logrus.Debug("No changes in metadata version")
} else {
logrus.Debugf("Metadata Version has been changed. Old version: %s. New version: %s.", version, newVersion)
version = newVersion
}
time.Sleep(5 * time.Second)
}
}
```
