Is it possible to configure the apm properties on a yaml file? I'm trying to configure on a spring-boot application but I think it is getting the default configuration :(.

SpringBootApplication.java

public static void main(String[] args) {
	ElasticApmAttacher.attach();
	SpringApplication.run(CpoEventsKafkaApplication.class, args);
}

pom.xml

<dependency>
    <groupId>co.elastic.apm</groupId>
    <artifactId>apm-agent-attach</artifactId>
    <version>1.50.0</version>
</dependency>

application.yml

elastic:
  apm:
    enabled: true
    application_packages: com.####.cpoeventskafka
    capture_body: true
    server_url: http://10.###.##.5:8200
    environment: dev
    service_name: cpo-event

Spring-boot log showing trying to connect to ip 127.0.0.1 no 10.###.##.5

I didn't find in any documentation using a yaml file.

ElasticApmAttacher has several attach methods that may be what you want. yaml is not supported but a simple properties file or directly setting properties are both supported
