EKS kubernetes.config.config_exception.ConfigException: Service host/port is not set.

[ashish-aesthisia]

What happened (please include outputs or screenshots):
Error while trying to access the kubernetes functions from within the cluster.

main.py

requirement.txt

Error

What you expected to happen:
List all the pods

How to reproduce it (as minimally and precisely as possible):
Python: 3.10-alpine(Dockerimage)
Kubernetes: 1.24
Hosted on: EKS

Tried all the available documentation. I do have KUBERNETES_SERVICE_HOST & KUBERNETES_PORT in env as well inside pod.yaml.

Any help would be appreciated.
Thanks

@ashish-aesthisia The issue is the way you are loading the config.Please change the code from config.load_incluster_config() to config.load_config()

You need to use config.load_incluster_config() when you are running inside the cluster.

Hey @venukarnati92, I have tried both, I am running this code within the EKS cluster, hosted on the python container. config.load_config() also doesn't work here, because kubeconfig is not available inside the pod.

@ashish-aesthisia Where you able to run other api calls like create secret or read secret from your cluster .This test is to rule out that you are able to load the kubeconfig within the cluster.

A quick test can be from your terminal run the following steps

$ python3
Python 3.7.10 (default, Apr 13 2022, 13:56:42)
[Clang 12.0.5 (clang-1205.0.22.11)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

from kubernetes import config
config.load_config()

[ashish-aesthisia]

load_config() doesn't work but config.load_incluster_config() from within the container

[venukarnati92]

@ashish-aesthisia In the screenshot shared above I see you were able to list the pods using config.load_incluster_config().Looks like you are getting the EXCEPTION when you are adding the host details.Just curious to know why you are setting the host details ?

If it's not needed please remove that and you will not see the exception.

I think it's working now, Thanks.
