Set Quarkus Logging Category Level via Environment Variables

Question

In Spring, it is possible to set the Logging Category Level via environment variables. I've tried the same in a Quarkus application with the following logger declaration:

package org.my.group.resteasyjackson;

public class JacksonResource {

  private static final Logger LOGGER = LoggerFactory.getLogger(JacksonResource.class);
  
  @GET
  public Set<Quark> list() {
    LOGGER.info("Hello");
    return quarks;
  }
}

Executing the build artifact with

QUARKUS_LOG_CATEGORY_ORG_MY_LEVEL=WARN java -jar my-artifactId-my-version-runner.jar

will log anything at info level (since it is the default), therefore the "Hello" message.

However, inserting

quarkus.log.category."org.my".level=WARN

in the application.properties file works as desired. Are environment variables in this use case not usable for Quarkus applications?

Just tried with quarkus 1.13.1 and adding extra underscores for the quotes seems to work, try:

QUARKUS_LOG_CATEGORY__ORG_MY__LEVEL=WARN
