And Linux… lies. I’ve recently discovered an interesting “quirk” in potential interactions between Java, cgroups, Docker, and the kernel which can 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 In Java 10, memory limits are automatically recognized and enforced.

Se hela listan på blog.softwaremill.com In the previous blog, We have seen that Java has made improvements to identify the memory based on a running environment i.e. either a physical machine or a Container (docker). 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.

Taking into account the maximum Heap Memory we establish and the Non-Heap Memory, which in our example reaches about 158Mb, we can set the memory limit of the Docker container. It is important not to limit the container memory only to the necessary by the Java process , since we must leave some space for other resources that are necessary for the container.

Docker 容器达到 Memory Limit 后的行为. 当一个容器申请使用多于整个主机可用的内存时, 内核可能会杀掉容器或者是Docker daemon(守护进程)来释放内存, 这可能会导致所有服务不可用, 为了避免这个错误, 我们应该给每个容器限制合适的内存. Unfortunately, there is no CPU or memory namespace (also namespaces usually have a slightly different goal), so a simple less /proc/meminfo from inside the container will still show you the overall memory on the host.
