potiuk opened a new issue #20588:
URL: https://github.com/apache/airflow/issues/20588


   ### Discussed in https://github.com/apache/airflow/discussions/20587
   
   Seems that when `AIRFLOW__WEBSERVER__BASE_URL` is used the path for health 
check is not correctly set. 
   
   It is properly  configured if base ul is set via config though:
   
   ```
             livenessProbe:
               httpGet:
                 path: {{if .Values.config.webserver.base_url }}{{- with 
urlParse (tpl .Values.config.webserver.base_url .) }}{{ .path 
}}{{end}}{{end}}/health
                 port: {{ .Values.ports.airflowUI }}
   ```
   
   We should either warn the user when variable is used rather than config, or 
fix it so that also env var could be used.

   I've changed base_url and enable_proxy_fix environment variable and I got:
