resources: requests: memory: "512Mi" limits: memory: "1Gi" . The Containers run OpenJDK 11 so per default it should respect the container memory limits and not overrun them. So based on the above parameters if we have a 2GB memory docker container, we can run the java application by using the below java arguments. java -Xms1250M -Xmx1250M -XX:+UseG1GC - XX:+UseStringDeduplication -XX:MinHeapFreeRatio=5 -XX:MaxHeapFreeRatio=10 -jar java-application .

The initial problem with java was that It wasn't able to figure out that it was running in a container and It used to capture the memory for whole hardware where the container was running. Java code running inside the JVM was trying to allocate a lot of memory. JVM, after checking that there is plenty of memory to use below 3GB Xmx limit asked for more memory from the operating system. Docker verified that there is plenty of memory to use below its 4GB limit and did not enforce any limits.

I would recommend to read this article before you proceed with the current one. Java Memory Consumption in Docker and How We Employed Spring Boot If your Docker container is consuming far too much memory to achieve optimal performance, read on to see how one team found a $ docker run --rm -ti -e JAVA_OPTS="-Xms50M -Xmx50M" openjdk-java INFO: Initial Memory (xms) : 50mb INFO: Max Memory (xmx) : 48mb We should note that there is a slight difference between the -Xmx parameter and the Max memory reported by the JVM. Docker memory resource limits and a heap of Java — blog post. Memory Footprint of a Java Process-Video from GeekOUT conference. Thank you for reading!

The issue is that if Xmx option is not defined explicitly, then JVM uses 1/4th of all memory available for the host OS due to a default internal garbage collection (GC) ergonomic algorithm. When we compared dockerized application with normal java application, performance of dockerized appliction was not good.
