While adjusting some environment variables recently, I came across an odd issue with Docker, Spring Boot and JAVA_OPTS. JAVA_OPTS comes from the Tomcat/Catalina world and when searching for "Docker and javaopts" on Google you'll find many references to just adding JAVA_OPTS to the Docker environment. After some testing, I found this to be incorrect when running a Spring Boot jar in a Docker

If memory leaks are not handled, an application can eventually run out of memory and terminate with an 'OutOfMemoryError', which is irrecoverable. What Causes Memory Leaks in Java. In general, a Java memory leak happens when an application unintentionally (due to logical errors in code) holds on to object references that are no longer required. 2017-10-18 · In Containerizing Continuous Delivery in Java, we explored the fundamentals of packaging and deploying Java applications within Docker containers.This was only the first step in creating production-ready, container-based systems.

Here you can see when docker container’s memory is set to ‘-m 1GB’ and ‘-XX:MaxRAMPercentage=50’. Based on this setting, JVM is allocating Max heap size to be 494.9MB (approximately half of 1GB). Note: Both ‘-XX:MaxRAMPercentage’ and ‘-XX:MinRAMPercentage’ are used to determine the maximum Java heap size. After I deployed several Java Docker containers on my self managed Kubernetes cluster I recognized that the containers consume much more memory as defined in the Kubernetes resource limits.

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.

Runtime options with Memory, CPUs, and GPUs. Estimated reading time: 16 minutes. By default, a container has no resource constraints and can use as much of a given resource as the host’s kernel scheduler allows. Docker provides ways to control how much memory, or CPU a container can use, setting runtime configuration flags of the docker run 2019-10-03 · If you run docker stats on that host, you should see something like: NAME CPU % MEM USAGE / LIMIT MEM % no-limits 0.50% 224.5MiB / 1.945GiB 12.53% This output shows the no-limits container is using 224.2MiB of memory against a limit of 1.945GiB.

2020-10-27 · Thankfully, Docker provides pre-built Java images which you can easily pull from the Docker registry and can instantly start building your Java applications. You can also extend this to create a spring environment and all other Java enterprise platforms and can work on Java applications on a large scale.

Also, worth nothing to mention that CPU limits can affect Java application in various ways. Monitoring Java application performance through JRE metrics. The Java Runtime Environment (JRE) that we’ll be discussing today contains a lot of general information about how your application is doing including, CPU usage, number of threads running, number of classes loaded, garbage collector information, memory usage, and other relevant metrics.
