You should take a look in the log-files. Are there error messages or can you see, wheter the ARGS reach the startup process?
I had some trouble to add the JMX Options on keycloak-16, the ser failed to start afterward. Then I found this article. This works for me.
If you run the docker image on a remote host, you can copy the jboss-cli-client.jar to your local maschine. And after each startof the container you have to add the user again.
