I'm new to Kubernetes and Helm and want to create a SSO with OIDC using vouch-proxy I found a tutorial which explains how to do it and was able to write some helmfiles that were accepted by kubernetes.

I added the ingress configuration to the values.yaml that I load in my helmfile.yaml.

helmfile.yaml

bases:
- environments.yaml

---

releases:
  - name: "vouch"
    chart: "halkeye/vouch"
    version: {{ .Environment.Values.version }}
    namespace: {{ .Environment.Values.namespace }}
    values:
    - values.yaml

values.yaml

# vouch config
# bare minimum to get vouch running with OpenID Connect (such as okta)
config:
  vouch:
    some:
      other:
      values:
# important part
ingress:
  enabled: true
  hosts:
  - "vouch.minikube"
  paths:
    - /

With this configuration helmfile creates an Ingress for the correct host, but when I open the URL in my Browser it returns a 404 Not Found which makes sense, since I didn't specify the correct port (9090).

I tried some notations to add the port but it lead to either helmfile not updating the pod or 500 Internal Server Errors.

How can I add a port in the configuration? And is it the "correct" way to do it? Or should ingresses be handled by kubectl still?
