Using pykube inside the cluster

[diegodelemos]

Hello,

Is pykube prepared to be executed inside a pod and make calls to the Kubernetes API? I need to query it to know the state of a Job, and if it has not ended (no successful nor fail) I would like to wait until it happens.

Thanks so much!

I suppose it is possible since here config.py is prepared to retrieve the credentials from a pod.

To give an official answer, yes, pykube is very capable of making calls within the cluster. The classmethod you link to is exactly the way to do it too.

I can vouch for pykube running in-cluster in production and it works great!

How do you use it within the cluster? I get an error because the api object does not have a config attributes.

MWE:

import pykube                  
api = pykube.KubeConfig.from_service_account()             
pykube.Service.objects(api)

Error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/dist-packages/pykube/objects.py", line 17, in __call__
    namespace = api.config.namespace
