kubernetes-config fails on proxy

[hakuseki]

Hi

I have an issue with my Quarkus application where I need to use the kubernetes-config extension.

When adding it to the pom and starting quarkus:dev it fails due to missing proxy URL:

2023-11-16 09:51:39,452 ERROR [io.qua.run.Application] (Quarkus Main Thread) Failed to start application (with profile [dev]): java.lang.RuntimeException: Failed to start quarkus at io.quarkus.runner.ApplicationImpl.doStart(Unknown Source) at io.quarkus.runtime.Application.start(Application.java:101) at io.quarkus.runtime.ApplicationLifecycleManager.run(ApplicationLifecycleManager.java:111) at io.quarkus.runtime.Quarkus.run(Quarkus.java:71) at io.quarkus.runtime.Quarkus.run(Quarkus.java:44) at io.quarkus.runtime.Quarkus.run(Quarkus.java:124) at io.quarkus.runner.GeneratedMain.main(Unknown Source) at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:103) at java.base/java.lang.reflect.Method.invoke(Method.java:580) at io.quarkus.runner.bootstrap.StartupActionImpl$1.run(StartupActionImpl.java:113) at java.base/java.lang.Thread.run(Thread.java:1583) Caused by: java.lang.IllegalArgumentException: Failure in creating proxy URL.

If I remove the dependency my app is starting.

Running on Quarkus 3.5.1 and Java 17

Please advice, thank you

Up'ed to 3.5.2 with same results…

Running on a Mac with Docker Desktop

Could you paste your (redacted - no secrets, no hosts in clear text) configuration?

[hakuseki]

There are no configs, I just added the extension as a dependency and when running in dev it fails

[gsmet]

@manusa is is something you could have a look at? I'm not sure we are instantiating the Kubernetes client properly for the proxy configuration?

[manusa]

I can try to take a look.

It looks like you might have some environment variables to define a PROXY and the Kubernetes Client is picking them. However, these variables provide an incomplete PROXY setting.

Just like Guillaume suggested for the config, could you please provide a redacted list of your current environment variables (run the env command in a terminal).

Removing the ALL_PROXY worked but I need it unfortunatly.

[manusa]

I've opened fabric8io/kubernetes-client#5605 for further investigation, we can continue dealing with the issue there.

[hakuseki]

This seems to related to the ALL_PROXY environment variable. If I use the correct way according to my company using http_proxy and https_proxy, then it works

[manusa]

After digging for a while, the problem is that you're not specifying the scheme/protocol in your all_proxy value.
If you set with either:

ALL_PROXY=http://proxy-se-uan.ddc.teliasonera.net:8080

or (whatever applies)

ALL_PROXY=https://proxy-se-uan.ddc.teliasonera.net:8080

It should work.

We'll work upstream to improve the error message or maybe support partial configuration such as this one.
