Ingress setup in stackstorm HA in kubernetes

Hi Team,

Need help in ingress setup in stackstorm HA in kubernetes .

Following the below link:

stackstorm-dev.company.com is added in the load balancer server mI can ping and login to the IP

I wanted to know how to setup such the stackstorm UI uses only on port 80 or 3030 for example and hostname
instead of IP

getting the below error

503 Service Temporarily Unavailable
nginx/1.17.10

####################

ingress:

As recommended, ingress is disabled by default.

enabled: true

Annotations are used to configure the ingress controller

annotations:
kubernetes.io/ingress.class: nginx
kubernetes.io/tls-acme: “true”

Map hosts to paths

hosts:

# Map paths to services

 paths:
   - path: /
     serviceName: st2web
     servicePort: 80

Secure the Ingress by specifying a secret that contains a TLS private key and certificate

tls: []

- secretName: chart-example-tls

hosts:

- chart-example.test
