All components of Elastic are 7.6.2  
Installed from Docker images and deployed on Kubernetes.

I'm able to send data from APM agent associated with a nodejs application by making the following code changes and APM dashboard is showing the transactions properly.

```auto
var apm = require('elastic-apm-node').start({
  serviceName: 'chd',	
  serverUrl: 'http://common-elk-apm-server.default.svc.cluster.local:8200',	
});

```

I would like to know, is there a way I can setup an agent for nodejs application without making changes in application code. Is there a way I can configuration this in kubernetes yml file or something ?
