dvoros/induce-jvm-oom repository overview

⁠dvoros/induce-jvm-oom

This is a Docker image that spawns a JVM that will fill up its heap quickly. Useful for testing containerized environments for what happens on OOM (e.g. shipping heapdumps from a k8s cluster).

⁠Usage

docker run dvoros/induce-jvm-oom:latest

Use JAVA_OPTS environment variable to pass JVM options. E.g. dump heap on OOM to directory on host:

mkdir -p /tmp/heapdumps
docker run \
    -e 'JAVA_OPTS=-Xms1G -Xmx1G -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/vol' \
    -v /tmp/heapdumps:/vol \
    dvoros/induce-jvm-oom:latest

⁠Build jar with

./gradlew clean jar
