Grouper container v2.6 change JVM

Grouper container v2.6 change JVM

Jul 01, 2026

Generally you should keep the JVM in the Grouper container.  But if you are running a different processor architecture or for other reasons you might need to change it.  This is available in v2.6.6+ (not released as of 2021/12/16).

This example shows going to openjdk.  Note, you should install the devel java which has javac

Dockerfile

FROM i2incommon/grouper:2.6.6 # remove current java RUN rpm -e `rpm -qa | grep java-1.8.0-amazon-corretto-devel` # install new devel java RUN yum install -y java-1.8.0-openjdk-devel # set env var for java and grouper java ENV JAVA_HOME=/usr/lib/jvm/java-1.8.0 ENV GROUPER_JAVA_HOME=/usr/lib/jvm/java-1.8.0

 

 Build this

docker build -t groupernewjava .

Run it and check
