Jenkins on Heroku

Jenkins on Heroku

  1. Download jenkins.war
  2. Create pom.xml (it'll be pretty much empty)
  3. Create Procfile to do 'java -jar jenkins.war' etc...

Deploy!

Just need a plain and mostly empty pom.xml for Heroku to detect that this is a Java application

@maheshwarimani1991 password is store on ~/.jenkins or $JENKINS_HOME. However, if you first start or restart dyno, you can access its log to get the pass code.
heroku logs --app your-app-name

@satnam348 I am facing the same issue, after 4 or 5 hours it is asking me for the Administrator password. Anyone know why?

To get initial password restart the Dyno and type
heroku logs --app your-app-name where you installed heroku cli

Where does the jenkins create its configuration files in heroku after it has been deployed using this approach.

Since Heroku is not persisting the configuration files after restart so I want to keep all these configuration files inside the git. So after restart I do not need to configure again and it will pick from the config files. Is it possible ?
