Hi, This message is only intended to help people facing the same problem than me : I use a customized DockerFile previously found in [https://github.com/denvazh/gatling](https://github.com/denvazh/gatling) (thanks btw) Everything works well in Docker. Then I built and uploaded my image to Kubernetes and deployed my pod containing the last version of Gatling. When I launched gatling.sh -s MyClass I had this message : The requested class ‘MyClass’ can not be found in the classpath or does not extends Simulation But the MyClass.scala file was already in /opt/galing/user-files/simulations folder ! I removed the stdout redirection from the compliation command line in gatling.sh and here is the output : Warning: Unknown option -s Warning: Unknown argument ‘MyClass’ Killed → compilation fails silently, gatling program cannot find the compiled classes and cannot load simulations. After having removed cpu and memory limits on my k8s pod, everything works like a charm ! Regards, Christophe
