Jenkins Groovy enable security and create a user in groovy script

groovy-create-user.md

This is a snippet that will create a new user in jenkins and if security has been disabled , it will enable it :)

import jenkins.model.*
import hudson.security.*

def instance = Jenkins.getInstance()

def hudsonRealm = new HudsonPrivateSecurityRealm(false)
hudsonRealm.createAccount("MyUSERNAME","MyPASSWORD")
instance.setSecurityRealm(hudsonRealm)
instance.save()

Bonus: Add the created user as admin for jenkins: what if you want that user to be like admin of jenkins who can access anything.. no problem..just add following lines right above the 'instance.save()' statement and run :)

def strategy = new GlobalMatrixAuthorizationStrategy()
strategy.add(Jenkins.ADMINISTER, "myUSERNAME")
instance.setAuthorizationStrategy(strategy)

Seems as if GlobalMatrixAuthorizationStrategy does not longer exist in Jenkins 3.

The "FullControlOnceLoggedInAuthorizationStrategy" works for me:

def strategy = new hudson.security.FullControlOnceLoggedInAuthorizationStrategy()
strategy.setAllowAnonymousRead(false)
instance.setAuthorizationStrategy(strategy)

Thanks! And thanks for the matrix fix @toweih!

This is really awesome!!! You made my task so simple

To use the GlobalMatrixAuthorizationStrategy you must install matrix-auth plugin

Thanks a ton! This is exactly what I was looking for.

Hi, what if I need more finer granularity for access to certain resources, such as Developer, or Tester role.

You can use Role Role Strategy plugin and configure finer permissions as shown in this script -> https://github.com/cloudbees/jenkins-scripts/blob/master/RBAC_Example.groovy

How to modify this script to this user to a specific existing group in Jenkins?
