If you need to learn how to run, tune, and maintain JVM applications that run in Docker and/or Kubernetes then this is the course for you.This course is very different from other Java/Docker/Kubernetes courses. It focuses on all the skills that you need to succeed in production.All of the examples are in Java but the content is applicable for any JVM language including Scala, Groovy, and Kotlin.We\'ll start with introductions for Docker and Kubernetes then we\'ll get into the fun stuff. We\'ll learn:What a container is under the coversLinux cgroupsLinux namespacesThen we will go into how the JVM and your Java application behave differently in Kubernetes when running inside cgroups and namespaces. We\'ll cover:JVM ergonomicsHow CPU Shares and Quota workHow Kubernetes manages CPU and Memory Then we will teach you all the techniques needed to build production-ready images:Selecting a base imageJDK vs JRE based imagesMulti-stage Docker buildsGraalVMClass data sharingAhead of time compilationWe will experiment with different JVM versions and settings.By the end of this course you\'ll know how to:Build a production-ready imageSelect between using CPU limits, quotas, or both in KubernetesSelect memory limits and tune the JVM for running in KubernetesUnderstand CPU usage in Kubernetes and know why it is different to VMs and physical machines.
