I want to get Secret object from k8s cluster using go-client API
I have function that looks like that
func GetSecret( version string) (retVal interface{}, err error){
clientset := GetClientOutOfCluster()
labelSelector := metav1.LabelSelector{MatchLabels: map[string]string{"version":version}}
listOptions := metav1.ListOptions{
LabelSelector: labelSelector.String(),
Limit: 100,
}
secretList, err := clientset.CoreV1().Secrets("namespace").List( listOptions )
retVal = secretList.Items[0]
return retVal, err
}
GetClientOutOfCluster is basically retrieves configuration from cluster or from local ~/.kube/config
I used metav1.LabelSelector just like i do when i generate new Deployment object.So i thought i was cool. But ListOptions.LabelSelector is a string. When i run my function it fails.
unable to parse requirement: invalid label key "&LabelSelector{MatchLabels:map[string]string{version:": name part must consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyName', or 'my.name', or '123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9]')
I cannot find example of usage of this function anywhere. Documentation assumes that you know what is LabelSelector.
What is format of LabelSelector for ListOptions?
Thanks
