mureco opened a new issue, #43910:
URL: https://github.com/apache/airflow/issues/43910
### Official Helm Chart version
1.15.0 (latest released)
### Apache Airflow version
v2.9.3
### Kubernetes Version
v1.30.0+k3s1
### Helm Chart configuration
values.yaml
```
# Airflow webserver settings
webserver:
enabled: true
replicas: 1
webserverConfigConfigMapName: airflow-webserver-config
```
airflow-webserver-config:
```
---
apiVersion: v1
kind: ConfigMap
metadata:
name: airflow-webserver-config
stringData:
webserver_config.py: |-
import os
from __future__ import annotations
from flask_appbuilder.const import AUTH_DB
basedir = os.path.abspath(os.path.dirname(__file__))
log = logging.getLogger(__name__)
WTF_CSRF_ENABLED = True
WTF_CSRF_TIME_LIMIT = None
AUTH_TYPE = AUTH_DB
```
### Docker Image customizations
I use the default image docker.io/apache/airflow:2.9.3
### What happened
When I specify a custom webserver config in my values.yml with
```
webserver:
webserverConfigConfigMapName: airflow-webserver-config
```
the webserver pod gets status CrashLoopBackOff and the pod logging is:
```

### What you think should happen instead
The content of webserver_config.py should be replaced with the content
specified in the ConfigMap.
### How to reproduce
- Deploy airflow helm chart 1.15.0 on kubernetes v1.30.0+k3s1. All pods will
spin up and airflow is operational.
- Add a ConfigMap containing a custom webserver_config.py
- Update the helm release
