Run a Spring Boot application with elastic-apm Java agent on OpenShift

I want to deploy a Spring Boot application on an OpenShift cluster that I want to monitor with elastic-apm, therefore, with the JAVA elastic agent.

I managed to deploy in a project an Elasticsearch instance, a Kibana instance and an apm-server.

Next to that, I also managed to deploy my Spring Boot application. For this I used the web console. I imported my project from GitLab, and chose the Java 8 image builder. However, using this method, I didn't find a way to launch my application by associating the java-agent elastic-apm-agent.

Locally, I run this command to start my application:

mvn package && java -javaagent:elastic-apm-agent/elastic-apm-agent-1.26.0.jar \
-Delastic.apm.service_name=ms-salarie \
-Delastic.apm.server_urls=http://localhost:8200 \
-Delastic.apm.secret_token= \
-Delastic.apm.environment=development \
-Delastic.apm.application_packages=com.leanerp.salarie \
-Delastic.apm.config_file=elastic-apm-agent/elasticapm.properties \
-jar target/salarie-1.1.3-SNAPSHOT.jar

Is there a way to override the command launched by the container of my application? Or another solution allowing me to use the elastic-apm-agent?

I am a newbie on OpenShift, so I don't fully understand all the concepts.

Ok, so the answer was adding this environment variable :

JAVA_OPTS_APPEND=-javaagent:{{path_to_elastic_apm_agent}}

this command allows you to launch your java application with options.

The Java agent allows multiple ways to configure it, one of which are command line system properties. Others include packaging an elasticapm.properties resource file or setting environment variables.

Check out the docs. Small excerpt:

  • Properties file: The elasticapm.properties file is located in the same folder as the agent jar, or provided through the config_file option. dynamic config.

  • Environment variables: All configuration keys are in uppercase and prefixed with ELASTIC_APM_.

Different option sources have different priority and precedence.

To attach the agent to a running JVM process (from within your application), you can use the API to self-attach.
