title: Kubernetes Executor in apache airflow: Pod getting deleted immediately with error
body: <p>i am using apache airflow with KubernetesExecutor. I am running the setup in Minikube which is working fine that means whenever DAG triggers it generates pod for every task in the tag and delete the pod after task completion.</p>
  
  <p>Same i have in test Kubernetes env but when i trigger DAG there, it create the pod for first task in the DAG and that pod gets deleted immediately from the state like.. ContainerCreating -> Running - > Completed -> Error -> Terminating. Airflow UI have logs empty for that task so not able to check what caused the issue and rest of the dependent task fails automatically.</p>
  
  <p>Here are the env variables i am using</p>
