Where to set the System Properties in Jenkins?

Question

I am exploring the EC2 plugin of Jenkins. One of the issues reported is with the Authentication Timeout.

jenkins.ec2.bootstrapAuthSleepMs (default 30000)
jenkins.ec2.bootstrapAuthTries (default 30)

I am seeing this issue with my install and I am trying to set the properties accordingly. So far without any success. Where do you increase the default timeout values for a jenkins install as suggested on the Install page?

Solution

These are regular JVM system properties. Pass them using -Denkins.ec2.bootstrapAuthSleepMs=value and -Djenkins.ec2.bootstrapAuthTries=value on Jenkins startup. You need to edit the Jenkins configuration/startup script on disk and restart Jenkins to apply the changes.

In most Jenkins installations, this is the "JAVA_ARGS" variable in the Jenkins config or startup script. On ubuntu/debian, this is configured in /etc/default/jenkins.

In Jenkins 2.7.1 on CentOS the file is /etc/sysconfig/jenkins and the variable is JENKINS_JAVA_OPTIONS

I don't find sysconfig under /etc in Ubuntu 16.04, where does this exists ?
