Set the JAVAHOME environment variable to point to the base directory location where Java is installed on your machine. This is a nice way to test different jvm settings with just restarting the jvm. Looking at the sample code, we have a basic pom file that imports Spring Boot dependencies: 4.0.0 vc.c4.javaopts example-javaopts 0.0.1-SNAPSHOT Spring Boot Tomcat JAVA_OPTS Spring Boot Tomcat JAVA_OPTS Example 1.7 $ repackage We are assuming Java 1.7.0.60 as installed version for this tutorial. JAVAOPTS is an environment variable that you can set to pass custom settings to the Java Virtual Machine (JVM) that runs Liquibase. The usual JAVAOPTS can be used to override settings. I've created this repo as a test case and you can refer back to it when needed. We can choose our memory settings at runtime by specifying the JAVAOPTS environment variable: docker run -rm -ti -e JAVAOPTS'-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. After some testing, I found this to be incorrect when running a Spring Boot jar in a Docker container, I'll explain why and give a solution in this post.Д«efore I start, let's setup a basic test environment that prints out the current memory setup so we can test in various situations. I would like to add remote debugging java opts to the. 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. Is your feature request related to a problem Please describe. While adjusting some environment variables recently, I came across an odd issue with Docker, Spring Boot and JAVA_OPTS.
