Julian Montgomery commented on AIRFLOW-6754:
--------------------------------------------
I am also encountering this same exact. My scenario is I am using the
KubernetesExecutor on Openshift. When I trigger a DAG I can see a Pod gets
created and a container runs on that dynamically created Pod. However, it fails
fairly quickly with this error:

PermissionError: [Errno 13] Permission denied:

---
The pod that gets created is configured with the following volume mounts:
{{airflow-dags → /usr/local/airflow/dags}}
{{airflow-logs → /usr/local/airflow/logs}}
The file /usr/local/airflow/unittests.cfg is actually there and has permissions
that would allow it to be read. I'm suspecting what is happening is
configuration.py executes the following line of code:
{{if not os.path.isfile(TEST_CONFIG_FILE)}}
Because it can't see the file it returns true so then it attempts to execute
this line of code:
{{with open(TEST_CONFIG_FILE, 'w') as file:}}
And then that fails with a Permission Denied error. At this point I'm stuck. If
there is a solution I am overlooking please let me know, otherwise it would be
great if there could be a code fix for this issue.
