Hi nifi was installed as a service. I stopped it and started another instance of nifi (not as a service) and worked correctly (but still not with "executescript" as you said it uses Jython).
At the beginning, I thought I should restart the nifi that is installed as a service (may be then nifi service will recognize the newly installed docker module). But even so, nifi service didn't recognize the docker module. Only when I start nifi NOT as a service, it works correctly. Regards
