Accessing minikube via the KubernetesPodOperator in airflow

Question

I am trying to make the airflow KubernetesPodOperator work with minikube. But unfortunately, the operator does not find the kubernetes cluster.

The dag returned to me the following error:

ERROR - HTTPSConnectionPool(host='192.168.49.2', port=8443): Max retries exceeded with url: /api/v1/namespaces/default/pods?labelSelector=dag_id%... (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f9a63cdcc10>: Failed to establish a new connection: [Errno 110] Connection timed out'))

I suspect an error in my config file definition which you will find below. The server address I used is the one return by minikube ip.

apiVersion: v1

- cluster:
    certificate-authority: ./ca.crt

Any ideas of what I could have done wrong?

Thanks!
