In the kubernetes client-go API (or another library that uses it), is there a utility function to convert a k8s.io/apimachinery/pkg/apis/meta/v1/LabelSelector
to a string to fill the field LabelSelector
in k8s.io/apimachinery/pkg/apis/meta/v1/ListOptions
?
I digged through the code of client-go
but I can't find a function like that.
The LabelSelector.Marshall()
nor LabelSelector.String()
give me that (unsurprisingly, because that's not their purpose, but I tried it anyway).
Background
I have spec descriptions like k8s.io/api/extensions/v1beta1/Deployment
, and want to use it's set of selector labels (i.e. the Selector
field) to query it's pods using
options := metav1.ListOptions{
LabelSelector: <stringified labels>,
}
podList, err := clientset.CoreV1().Pods(<namespace>).List(options)
