QUESTION
I try the code delivered with "quarkus-quickstarts"/"kafka-quickstart" and get this error message:
Caused by: org.apache.kafka.common.config.ConfigException: No resolvable bootstrap urls given in bootstrap.servers
For the QuoteProcessorTest.java class.
I'm wondering since the code is delivered by quarkus so I expect it to work without any errors.
...ANSWER
Answered 2022-Mar-10 at 13:31According to the README, the code is intended to run with a pre-installed Kafka broker, such as one provided by Docker Compose - https://github.com/quarkusio/quarkus-quickstarts/blob/main/kafka-quickstart/docker-compose.yaml
The tests themselves do not appear to be using any mocked / local broker, so you may need to start Kafka on your own, or skip the tests when building the project
Or if you used the quarkus:dev commands listed, it says Kafka should start automatically
QUESTION
When starting Quarkus 2.7.1 with dev services enabled for KeyCloak, you can specify quarkus.keycloak.devservices.realm-path=realm.json in the application.properties.
The documentation for this property just says:
The class or file system path to a Keycloak realm file which will be used to initialize Keycloak.
It does not clearly state relative to what base directory the path is being resolved.
There are example projects where the file is placed inside a config/ subdir. I tried this as well as in the project's root dir. Neither location seems to work, the file is ignored and Quarkus creates a realm with its default values instead.
Specifying an absolute path works just fine.
...ANSWER
Answered 2022-Feb-17 at 15:55Everything in the classpath is searched for the path specified in the property, e.g. resources dir.
The documentation already gives a hunch: "The class or ...", so at very least the classpath must be searched.
In the linked example project, in the maven pom the resources are extended to also include config, therefore it works there.

QUESTION
I'm trying to deploy a Quarkus app to a Kubernetes cluster, but I got the following stacktrace:
...ANSWER
Answered 2021-May-12 at 02:11It's due to the docker link variables that kubernetes mimics for Service names in scope; it bites people a lot when they have generically named services such as { apiVersion: v1, kind: Service, metadata: { name: http }, ... as it will cheerfully produce environment variables of the form HTTP_PORT=tcp://10.233.12.82:80 in the Pod, and things such as Spring boot or evidently Quarkus which coerce env-vars into configuration overrides can cause the exact outcome you're experiencing
The solution is (a) don't name Services with bland names (b) "mask off" the offensive env-vars for the Pod:
QUESTION
I am trying to understand the behavior of Uni in Quarkus framework, after checking out their official tutorial getting started with async guide. In the service method I have made the following changes
...ANSWER
Answered 2021-May-10 at 21:53The problem is in Uni.createFrom().item(ioSimulation(name)). You synchronously call ioSimulation before the Uni is created.
You should at least use the Supplier variant: Uni.createFrom().item(() -> ioSimulation(name)). That should help.

I use Quarkus + Hibernate to sync data to the DB and I've noticed during testing that sometimes my entity isn't updated. I've created a minimal example adjusting the original example https://github.com/quarkusio/quarkus-quickstarts/tree/main/hibernate-orm-quickstart

I'm going to deploy a Java application using this docker image. I'm trying to eliminate the issue that the variable's value persists even after the response is generated. My assumption is to have an isolated environment per each request, BUT I'm not sure is correct or not.
For example, the given code block below will add the given URL param to a dummy list.
