Instead of setting the memory sizes per application and therefore disabling any container support for schedulers like Kubernetes, use the JAVA_TOOL_OPTIONS environment variable to augment the command-line.

For containerized tools the following memory settings can be used as a good rule of thumb:

JAVA_TOOL_OPTIONS="-XX:MinRAMPercentage=60  -XX:MaxRAMPercentage=80"

For explicit memory settings use

JAVA_TOOL_OPTIONS="-Xmx512m"
