How to trigger karate gatling distributed test? - karate

Question

We want to run karate gatling distributed mode to test API performance.
Here is the performance test class for master node
public class TestPerformanceDocker {
#Test
void test(){
//master node server ip
String serverUrl= "127.0.0.1";
String threads = System.getProperty("THREADS");
String rampDuration = System.getProperty("RAMP_DURATION");
String constantDuration =System.getProperty("CONST_DURATION");
//slave node amounts
Integer executorCount=Integer.parseInt(System.getProperty("NODES_COUNT"));
String cmd ="mvn gatling:test -DTHREADS="+threads+" -DRAMP_DURATION="+rampDuration+" -DCONST_DURATION="+constantDuration+"";
GatlingMavenJobConfig config = new GatlingMavenJobConfig(executorCount, serverUrl, 9090) {};
config.setMainCommand(cmd);
JobManager<Integer> manager = new JobManager(config);
manager.start();
manager.waitForCompletion();
}
}
Start the master node with cmd :
docker container run -d -t --network=karate_network --name karate_boss --privileged karate mvn clean test -Dtest=TestPerformanceDocker -DTHREADS=3 -DRAMP_DURATION=600 -DCONST_DURATION=600

With the reference article in official github, we want to run the karate-gatling with distributed mode for API testing.
