Problem setting quarkus.http.host in the integration-tests

[Michael Musgrove]

I also raised the following question via zulip but didn't get an answer so I hope you'll forgive me for cross posting ...

I'm writing an integration-test for an extension that I am developing.

The test starts an external service using docker testcontainers and then registers a test endpoint with the external service which the external service will invoke during the test.

The default value for the quarkus property quarkus.http.host is localhost. But the docker container will not be able to invoke the endpoint unless the endpoint is an actual IP address. I am testing it by relying on an environment variable: quarkus.http.host=${HOST:localhost} and setting HOST to one of my network interface addresses.

My question is how can I make this work more generally when quarkus runs the integration tests?

When you say integration test you mean a @QuarkusTest, a @QuarkusIntegrationTest or something else?

The test starts an external service using docker testcontainers and then registers a test endpoint with the external service which the external service will invoke during the test.

The default value for the quarkus property quarkus.http.host is localhost. But the docker container will not be able to invoke the endpoint unless the endpoint is an actual IP address.

You can likely set quarkus.http.host=0.0.0.0 (or better yet %test.quarkus.http.host=0.0.0.0) to make Quarkus bind to all hosts

My question is how can I make this work more generally when quarkus runs the integration tests?

The integration test is annotated with:

@QuarkusTest

@QuarkusTestResource(LRACoordinatorTestResource.class)

@TestHTTPEndpoint(TransactionalResource.class)

I did try quarkus.http.host=0.0.0.0 earlier.

And I have just tried %test.quarkus.http.host=0.0.0.0 without success.

[Michael Musgrove]

Actually my docker daemon isn't running so I let me retest use `%test.quarkus.http.host=0.0.0.0` ...

[Michael Musgrove]

No it still doesn't work:

quarkus.http.host=${HOST:localhost} works where HOST is set to one of my network interfaces

quarkus.http.host=0.0.0.0 doesn't work

%test.quarkus.http.host=0.0.0.0 doesn't work

Perhaps the issue lies with resteasy/quarkus integration. I get the address of the test endpoint via a JAX-RS request filter using:

containerRequestContext.getUriInfo().getBaseURI()

which returns http://192.168.0.14:8081/ when I set quarkus.http.host to one of my local interfaces

but returns http://localhost:8081/ when I set quarkus.http.host to 0.0.0.0

I also set quarkus.http.test-port=8081

Another option would be to launch the external service with host networking (--net=host in Docker terms).

With testcontainers you would do that by setting withNetworkMode("host") on the created container.

I'll raise the issue with the quarkus/resteasy integration team.

I raised a pr/17903 for our LRA extension. The windows test environment does not support docker:

> JVM Tests - JDK 11 Windows failed with "Could not find a valid Docker environment. Please see logs and check configuration"

Are you aware of a mechanism to disable windows testing for PRs that require docker?

The Quarkus repo does this actually.

It achieves it by making the execution of integration tests opt-in based on a flag that is not passed during the Windows run.

See https://github.com/quarkusio/quarkus/blob/2.0.0.CR3/integration-tests/hibernate-search-orm-elasticsearch/pom.xml#L142, https://github.com/quarkusio/quarkus/blob/2.0.0.CR3/.github/workflows/ci-actions-incremental.yml#L45 and https://github.com/quarkusio/quarkus/blob/2.0.0.CR3/.github/workflows/ci-actions-incremental.yml#L238

That's nice and should work for my testcase, I'll update my PR.

Thanks again for your help.
