Reduce default memory requirement for Java Runtime Environment to continue

Thanks for great tool!

In latest docker image default memory assigned runs into more than 100+GB.

sudo docker run --mount type=bind,source=/home/mindmap/app.properties,target=/usr/local/tomcat/webapps/ROOT/WEB-INF/app.properties -it --rm -p 8080:8080 wisemapping/wisemapping:latest
[sudo] password for xxx:

It will be great if the advanced option

$ docker run\ --mount type=bind,source<your-file-path/app.properties,target=/usr/local/tomcat/webapps/ROOT/classes/app.properties -m 1.5GB -e JAVA_OPTS=" -XX:+PrintFlagsFinal -XX:InitialRAMPercentage=30 -XX:MaxRAMPercentage=80" -it --rm -p 8888:8080 wisemapping/wisemapping:latest

is made default.

Kind regards
