FWIW, I was able to get a template working, though I’m still left with some 
questions. First, I upgraded to Airflow 2.0.0 largely because I saw it had 
logging statements. Second, I was only able to specify a pod_template_file in 
the scheduler config. The KubernetesPodOperator parameter doesn’t work. 
Similarly, overriding the pod image does not work by using the KPO’s image 
constructor parameter. I had to use the executor_config/pod_override method.

Am I missing the point of having those parameters in the KPO constructor? Are 
these legacy parameters that don’t work anymore and should be removed?

Thanks,
Peter

Hi Daniel,

Thanks for responding. Sorry for the months-long delay. Had other stuff I had 
to focus on.

I am using Airflow 1.10.12.

Here is a link to a public repo with the scheduler logs and template file:

https://github.com/MuffinSpawn/AirflowDebug/tree/main<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_MuffinSpawn_AirflowDebug_tree_main&d=DwMGaQ&c=iqeSLYkBTKTEV8nJYtdW_A&r=kvBf2hZ8ILK_fyYNp9ArlfEC5_dzeChyAb7MXIoSTUM&m=b-VRncu4Y9U-dqTAelnBF9fT6aI0HpEL8zGTbZiKqv0&s=qHmRWsG7QFeT9_jhgZuIwnZ4t3wqMlJbiMmw0NeJt5A&e=>

The Pod gives me the message “Failed to pull image "dummy_image": rpc error: 
code = Unknown desc = repository docker.io/dummy_image not found: does not 
exist or no pull access”.  The most recent run was an excerpt from this 
example: 
https://airflow.apache.org/docs/apache-airflow-providers-cncf-kubernetes/stable/_modules/airflow/providers/cncf/kubernetes/example_dags/example_kubernetes.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__airflow.apache.org_docs_apache-2Dairflow-2Dproviders-2Dcncf-2Dkubernetes_stable_-5Fmodules_airflow_providers_cncf_kubernetes_example-5Fdags_example-5Fkubernetes.html&d=DwMGaQ&c=iqeSLYkBTKTEV8nJYtdW_A&r=kvBf2hZ8ILK_fyYNp9ArlfEC5_dzeChyAb7MXIoSTUM&m=b-VRncu4Y9U-dqTAelnBF9fT6aI0HpEL8zGTbZiKqv0&s=gdyLjqHL1VeTO7UReGBOwOzU8PFjl4-suxzXeXzJbpU&e=>
 It’s in the repo as well as test_xcom.py. My understanding was that this 
should work as well with the template, substituting the image parameter for the 
dummy base image in the template. I also included my scheduler config YAML if 
that helps. Any help would be appreciated.

Peter

Hi Peter,

What version of airflow are you using? Can you post a link to your 
pod_template_file and the logs?

I am having a terribly difficult time getting Airflow to run on Kubernetes

custom worker pod template, but the default container image is not being 
replaced when I set the AIRFLOW__KUBERNETES__WORKER_CONTAINER_REPOSITORY and 
AIRFLOW__KUBERNETES__WORKER_CONTAINER_TAG in the deployment environment. I 
directly customized the git-sync example, and my init container works fine. The 
base container image can’t get pulled because the default value for the image 
(dummy_image) is still in the pod configuration. Is there some magic flag I 
need to set or something to get this to work?

Thanks,
Peter
