Reverting back to the original Jenkins
If you don't want to keep this Jenkins, it's easy to go back to the old one – simply delete the current controller and run the original again. Since everything in Jenkins is a flat file on the controller, all the configurations have persisted. You won't have to reconfigure anything, and you'll be back to right where you left it:
controller:~$ docker stop jcasc_controller
controller:~$ docker rm jcasc_controller
controller:~$ docker run \
--detach \
--restart on-failure \
-u $(id -u):$(id -g) \
-v ~/jenkins_home:/var/jenkins_home \
-p 8080:8080 -p 50000:50000 \
--name jenkins_controller \
calvinpark/jenkins:2.263.1-lts
Open a browser and navigate to the Jenkins URL. You should be able to log in as adder-admin and start adding more pipelines to the adder folder. If you're familiar with Docker commands, you can run multiple Jenkins instances on the same machine...
