I'm trying to run a DAG that have a task that is running a jupyter notebook. Every task is doing well until it get's to Papermill operator. the progress bar stay on 0 and the task never finish. when looking inside the pod there is an:

AirflowException : "Celery command failed on host <airflow-worker id>"
i'm using airflow 2.3.3 and the pod have papermill(2.4.0) and ipykernel(6.15.2) installed
Arflow is running on openshift

The solution was to give more ressources (cpu and memory) to the pod.

inside your dag:

from kubernetes.client import models as k8s

task_ressource = k8s.V1ResourceRequirements(limits={"cpu": "800m", "memory": "5Gi"}, request={"cpu": "200m", "memory": "2Gi"})
task = KubernetesPodOperator('task_id'='task_id',image='your image',resources=task_ressource)
