How to set heap size for Quarkus app using Jib container image?

Question

I'm Quarkus 1.11.0 and trying to set the heap size of my app using...

quarkus.jib.jvm-arguments=-Xms1024m -Xmx1024m -agentpath:/app/resources/libyjpagent.so=listen=all also tried with capital M and I get Invalid initial heap size and the app exits.

I also tried through the env JAVA_OPTS and JAVA_TOOL_OPTIONS and these don't seem to do anything, the app just runs but the heap size is not set.

Answer 1

In addition to geoand's answer, use a comma-separated list, like so:

quarkus.jib.jvm-additional-arguments=-XX:MaxRAMPercentage=75.0,-XX:+UnlockExperimentalVMOptions,-XX:+UseG1GC,-XX:MaxHeapFreeRatio=15,-XX:MinHeapFreeRatio=5

Answer 2

You can use quarkus.jib.jvm-additional-arguments if you just want to add arguments.
