--web.external-url breaks healthcheck to localhost

[nazarewk]

I am pretty sure this is exactly the same as prometheus/alertmanager#1382

This is interesting. In my case prometheus (2.2.1) healthcheck seems to work fine on localhost even if an external-url is set.
Du you use vanilla containers or do you build your own ones?

[nazarewk]

I'm using stable/prometheus with as little changes as possible (so yeah, vanilla containers)

[anthraxn8b]

@nazarewk, could you please try to set --web.external-url=https://yourDomain/yourPathPrefix --web.route-prefix=/ to enforce the route prefix not to be inherited by the web external url?
Also alter your healthcheck to point to wget --quiet --spider http://localhost:9090/graph to avoid being redirected to yourPathPrefix (this happens to serve the external url correctly - as far as it looks like the original request path is no longer taken into account if the web external url is set).
Please tell me if it worked! THX!

This looks like a misunderstanding of how --web.external-url works so it makes more sense to ask questions like this on the prometheus-users mailing list rather than in a GitHub issue. On the mailing list, more people are available to potentially respond to your question, and the whole community can benefit from the answers provided.

@brian-brazil, you are right, but this means you have to create another account on another platform - and if you believe in an issue this would be the right place ;-)
