geocomm-shenningsgard opened a new issue, #58650:
URL: https://github.com/apache/airflow/issues/58650
### Official Helm Chart version
1.18.0 (latest released)
### Apache Airflow version
2.10.x
### Kubernetes Version
1.32
### Helm Chart configuration
```yaml
webserver:
podDisruptionBudget:
enabled: true
config:
unhealthyPodEvictionPolicy: AlwaysAllow
maxUnavailable: 1
```
(same for scheduler, and for api-server in Airflow 3)
### Docker Image customizations
_No response_
### What happened
It appears the schema for the values file does not match the intention of
the template. The template at
`templates/webserver/webserver-poddisruptionbudget.yaml` has the following,
suggesting that the intention was to enable a user to supply arbitrary
configuration for the pod disruption budget:
```yaml
spec:
selector:
matchLabels:
tier: airflow
component: webserver
release: {{ .Release.Name }}
{{- toYaml .Values.webserver.podDisruptionBudget.config | nindent 2 }}
```
Yet, the schema prevents this. I need to be able to set
`unhealthyPodEvictionPolicy` so that the deployment responds appropriately in
the case that Pods are unhealthy.
### What you think should happen instead
The chart should either pass through any configuration supplied in
(component).podDisruptionBudget.config, or if the desire is to restrict to
valid configuration, allow all valid configuration values (such as
`unhealthyPodEvictionPolicy`).
### How to reproduce
Add something other than `maxUnavailable` or `minAvailable` (such as
`unhealthyPodEvictionPolicy`) to `webserver.podDisruptionBudget.config` and
deploy. You should get the following error:
```
Error: UPGRADE FAILED: values don't meet the specifications of the schema(s)
in the following chart(s):
airflow:
- webserver.podDisruptionBudget.config: Additional property <your-property>
is not allowed
```
