We run our Jenkins instance as a Docker container, like this

docker run --restart=unless-stopped -d -p 8080:8080 -v /mnt/jenkins_master/jenkins_home:/var/jenkins_home --name jenkins_master --memory=24g 0123456789.dkr.ecr.us-east-1.amazonaws.com/jenkins_master:lts

How can I set JAVA_OPTS="-Xmx8192m -Dhudson.util.ProcessTree.disable=true -Djdk.lang.Process.launchMechanism=vfork" with the above command?
