What happened

I have EKS where I have deployed Airflow using Helm chart. The pods are running on Fargate. I have ALB installed using helm as well. The UI shows up when accessing the Ingress URL. The issue comes when I am setting up a prefix. If I change the Base_Url value to locahost:8080/airflow-dev/ the webserver Pod keeps restarting. An If I change it back to localhost:8080 I am getting the 404 page when accessing the Ingress URL ?
Here is the error that I get:

Ideally I want to access the Airflow using the ingress_url/airflow-dev/ .

What you think should happen instead

Should be seeing the Airflow URL when using Prefix

How to reproduce

Set up ingress, ALB on EKS(fargate)

Health check path is not configured correctly if AIRFLOW__WEBSERVER__BASE_URL is set via env variable
There have been discussions about this before: #9778

Here is a quick solution. Add this to your helm chart instead of that env variable

config:
  webserver:
    base_url: http://localhost:8080/airflow-dev

Also don't forget to change the health check path to /airflow-dev/health in your ALB

How can I set health check path it's not available in values.yaml

[potiuk]

It's not needed, I thinl - this is an issue for a 2 years old chart which it is strange to refer to. In the latest chart you have this:

path: {{ if .Values.config.webserver.base_url }}{{- with urlParse (tpl .Values.config.webserver.base_url .) }}{{ .path }}{{ end }}{{ end }}/health

I believe it's good and uses the base url. if you have some other problems with heltcheck, please open a new issue explaining what problems you are having.

There is literally no point to comment on issue which has beeb closed a year ago. It's always better to open new one that has your circumstances, logs and evidences.
