headlampUrl issue when deployed with backstage and ngnix ingress

[navpreet-securitas]

i'm trying to use this plugin in backstage instances that is deployed in k8s exposed via public ingress (nginx). having headlampUrl containing port 4466 & FE calling this headlampUrl from browser end , this port needs to be exposed via nginx.

exposing 4466 port is not recommended and straightforward from nginx ingress. can this headlampUrl be changed to something like:

 const headlampUrl =
    config.getOptionalString('headlamp.url') ||
    `${window.location.protocol}//${window.location.hostname}/{somepath}`;

file link

having default ports (80/443) with some path/uri , will enable reaching it via same backstage url and on some path.

Hey, You can configure the headlamp.url value to point to your url with subpath.

we don't have headlamp deployed in cluster as separate instance. we are using backend Integration Mode.
so if our backstage url is https://devplatform.domain.com , i need to use this ? in headlamp.url

Since you are exposing headlamp via an Ingress you can use it in headlamp.url config.

we don't have dedicated / separate headlamp deployment. headlamp backend is running in integrated mode (with backstage plugin itself). Doing so , FE tries to call https://devplatform.domain.com:4466 . which is causing problem.
with Nginx ingress exposing 4466 port is not recommended.
if we create a proxy which maps https://devplatform.domain.com/headlampbe --> http://backstage.svc.cluster.local:4466
and then add https://devplatform.domain.com/headlampbe to headlamp.url , this also doesn't work.
headlamp.url expects dedicated headlamp deployment not integrated one

May I know what is happening in this case? Do you not see the Headlamp UI in the frontend or is it not loading the clusters from backstage to Headlamp?
