I am using the python kubernetes api with list_namespaced_pod to get the pods in my namespace. Now I would like to filter them, using the optional label selector parameter.
The documention describes this parameter as
A selector to restrict the list of returned objects by their labels. Defaults to everything.
It does not bother to give an example. On this website, I found several possibilities on how to use the attribute. I already tried
label_selector='label=my_label'
label_selector='label:my_label'
label_selector='my_label'non of which is working. How do I use the parameter label_selector correctly?
this works for me:
v1.list_namespaced_pod(namespace='default', label_selector='job_name={}'.format(name))Kubernetes CLI uses two types of label selectors.
Equality Based Eg: kubectl get pods -l key=value
Set Based Eg: kubectl get pod -l 'key in (value1,value2)'
label_selector='label=my_label'
should work, else try using
label_selector='label in (my_label1, my_label2)'.
If this does not work the error might come from somewhere else.
(Python client) This works for me and it returns JSON
result = v1.list_namespaced_pod( "default", label_selector="label_key=label_value",watch=False)
print(len(result.items))
