request help: why the location in response header that returned by APISIX has the 9443 port?

[shuoshadow]

Issue description

apisix前使用slb 443端口转发到apisix的9443端口
apisix 代理https请求后 携带了9443端口导致无法重定向

是因为header的原因吗？我配置了apisixroute的proxy-rewrite插件也不行

    - name: proxy-rewrite
      enable: true
      config:
        headers:
          "Host": $host

Environment

• your apisix-ingress-controller version (output of apisix-ingress-controller version --long);
• your Kubernetes cluster version (output of kubectl version);
• if you run apisix-ingress-controller in Bare-metal environment, also show your OS version (uname -a).

@shuoshadow Which action results in this redirect? Is this a behavior of APISIX itself or its backend?

Can you provide more detailed information?

I have encountered a similar situation

This is an already known problem, see #6686.

#6286 (comment)
This is not the best way

#6945 proxy-rewrite cannot modify X-Forwarded-Port same problem as mine

[Horus-K]

@shuoshadow Temporary workaround: Change the apisix port to 80 443

[tokers]

Or should apache apisix handle the port in redirect url by using the X-Forwarded-Port?

+1.

ref: #6945

https://apisix.apache.org/docs/apisix/plugins/redirect#example-usage

set apisix config.yaml

...
ssl:
enable: true
enable_http2: true
listen_port: 443
...

will redirect 443 port

Was this fixed on recent releases? Whats the recommended way going forward for this issue?

What's your version? Recent releases will check the X-Forwarded-Port header, so the redirect will be correct.

I am using the last available version of the apisix helm chart with default option.
When i try to access the keycloak admin console, APISIX redirects me as follows:
https://keycloak.mydomain.com:9443/admin/

Can you please give us the way to fix this please ?

@fbossiere Without a context, I didn't know if this is an issue or a normal scene.

[fbossiere]

The context is very simple. 1- You deploy apisix ingress controller on any 1.2x k8s cluster using the official documentation with default values yaml, then 2- you helm install keycloak with default values.yaml, together with 3- a standard apisix route + certificate Then you notice that this weird redirection occurs when you try to access the admin console of keycloak. Something is clearly going wrong with the X-forwarded-port but nothing in apisix-ingress-controller documentation tells us how to fix. This problem doesn't occur with nginx ingress controller, nor traefik. It basically has been preventing our company to use apisix until now.

a quick fix for this is setting the HTTPS port to 443 via the field: https://github.com/apache/apisix-helm-chart/blob/master/charts/apisix/values.yaml#L192.

[tokers]

@fbossiere If this is OK for you, would you like to submit a PR to mention it in the docs?

This configuration has the load balancer port set to 443, but if the port inside the container is 9443, it will still redirect to 9443.
