如何在基于 airflow 的 docker 上安装 Kube.netes 操作员和执行器

Question

I'm using Puckels docker file to build and run dags. I'm trying to create new dags that I can execute on a Kube.netes pod but I'm not sure how to get it working on the docker's airflow container. I tried adding to the docker file

pip install 'apache-airflow[kubernetes]'

then I tried adding the following line into my dag:

from airflow.contrib.operators import KubernetesOperator

This is the error message I get:

cannot import name 'KubernetesOperator' from 'airflow.contrib.operators' (unknown location)

Answer 1

The Kube.netesPodOperator is defined under the kube.netes_pod_operator . You should be using:

from airflow.contrib.operators.kubernetes_pod_operator import KubernetesPodOperator

Please also check out this Airflow documentation page .
