I’m new in Docker and Jenkins so I am not sure where is the error here. Basically I was using a docker to start a new Jenkins container, modify it, and commit (save) the work I’ve done on that container. And then I run that saved container image again but end up Jenkins in its initial setup wizard state. Here are the steps that I performed:
I run new Jenkins docker container from latest image from Jenkins
docker run -d --name Jenkins -u root -p 8080:8080 -v /var/run/docker.sock:/var/run/docker.sock -v /usr/local/bin/docker:/usr/local/bin/docker jenkins/jenkins
run bash on the Jenkins container
docker exec -it -u root Jenkins /bin/bash
apt-get install vim
install python 3
apt-get install python3
view the log to retrieve the secret key for initial jenkins install.
docker logs Jenkins
I went to my browser to access jenkins and administer it, created and ran a pipeline, then safeExit.
Believing I’ve applied all my changes, I’ve committed to docker my changes
docker commit -m "Jenkins initial setup + vim + python3" Jenkins elmachotroso/jenkins
I really don’t need to but I still pushed in to my repository in docker hub
docker push elmachotroso/jenkins
Stop Docker Jenkins container
docker stop Jenkins
docker rm Jenkins
Run new Jenkins container using recently created image elmachotroso/jenkins
docker run -d --name Jenkins -u root -p 8080:8080 -v /var/run/docker.sock:/var/run/docker.sock -v /usr/local/bin/docker:/usr/local/bin/docker elmachotroso/jenkins
At this point I’m back to Jenkins initial setup!!! 🙁
But vim and python3 I’ve installed before is there!
