I am using kong chart 1.5 with kong ingress controller 0.8.0 to deploy kong to our cluster via helm release.

I saw the service host has created automation when I set up via Ingress. Imagine it is `review-web.staging.80.svc`.

Now, I want to change it to another value. For example:

- Change it to domain `api.staging.example.com`
- Or point to another internal service `another-service.staging.80.svc`

By manual, I can do it, but I wonder how to do that via Kong Ingress?

You can set `upstream.host_header` in a KongIngress resource and then annotate your service using `konghq.com/override`. This will change the host-header to the value you prefer.

@hbagdi  
Let me show you my configuration:

```
---
apiVersion: configuration.konghq.com/v1
kind: KongIngress
metadata:
  name: demo-ki
  namespace: default
upstream:
  host_header: "echo.internal.local"
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: demo
  namespace: default
  annotations:
    konghq.com/override: demo-ki
spec:
  rules:
  - http:
      paths:
      - path: /foo
        backend:
          serviceName: echo
          servicePort: 80 

```

After I applied that config, I expect the value of the service host is `echo.internal.local`. But it is not the same.

Two things:

1. You need to put the `konghq.com/override` annotation on the Service resource for this to work.
2. You will still not see the the `host` property of Service change. You will see the `host_header` property of the corresponding `Upstream` change.

Thank you for your prompt reply.  
I have tested by following your guide and it worked with two things you noted.
