Spring boot admin Kubernetes Ingress

The problem is that your spring boot admin interface has no way to know that you're using "/admin" suburl.

nginx.ingress.kubernetes.io/rewrite-target: /$1 ask nginx to rewrite your url matching the second group.So when you're hitting: https://XXXXX/admin/ui nginx rewrite your url to https://XXXXXX/ui and then send it to spring boot.

I don't know well spring boot but you should have a way to provide him a suburl so instead of serving to /ui it server to /$BASE_URL/ui.

Then weather how it works you might need to change how nginx rewrite the url by something like:

• path: ^(/admin/)(.+)\
• nginx.ingress.kubernetes.io/rewrite-target: $1/$2

Finally I found the solution.

Spring boot admin has a tool for that called "public URL"

      spring:        application:          name: administrator-interface        boot:          admin:            context-path: "/ui"            ui:              public-url: "https://XXX/admin/ui"      server:        use-forward-headers: true

whith such configuration I am telling spring boot admin that i want to connect with a context /ui but when trying to load resources it should make the request to /admin/ui.

Now i can connect with the interface trought https:/XXX/ui and is sending request to load resources from https://XXX/admin/ui adding the prefix set by ingress
