jenkins docker image create first admin user

[Li Z]

I am trying to build a Jenkins docker image from jenkins/jenkins:2.67. Is there a way to create the first admin user with dockerfile? Thanks

Yes. Put this snippet into a .groovy file, e.g. usercreate.groovy:

    instance = Jenkins.getInstance()

    def hudsonRealm = new hudson.security.HudsonPrivateSecurityRealm(false)
    hudsonRealm.createAccount("admin","Password1234")
    instance.setSecurityRealm(hudsonRealm)
    def strategy = new hudson.security.GlobalMatrixAuthorizationStrategy()
    strategy.add(Jenkins.ADMINISTER, "admin")
    instance.setAuthorizationStrategy(strategy)
    instance.save()

Put the usercreate.groovy file next to your Dockerfile. Then add this line to your Dockerfile:

COPY usercreate.groovy /usr/share/jenkins/ref/init.groovy.d/

When Jenkins starts, a user with name "admin" will then be created with password "Password1234". Note the plaintext password, I'm not sure how to use a hash for this one.

This code will run every time Jenkins starts, so you may need to add a guard that checks if the admin user exists and only run the code if it does not exists.

Thanks Jacob! It is exactly what I am looking for.
