How can I increase memory for a Java application running in a container?

You can increase the memory available to a Java application by setting appropriate JVM options (JAVA_OPTS). When running inside containers (Docker/Kubernetes), Java respects container limits and can be tuned using RAM percentage–based flags.

JAVAOPTS=-JAVA OPTS=-Xms20g -Xmx25g -XX:+UseContainerSupport

This configures the JVM heap as a percentage of the container’s memory limit instead of a fixed -Xmx values, which is the recommended approach for containerized workloads.
