What is Jenkins?

Jenkins is an open source automation server written in Java. The project was forked from Hudson after a dispute with Oracle. Jenkins helps to automate the non-human part of the whole software development process, with now common things like continuous integration, but by further empowering teams to implement the technical part of a Continuous Delivery.

Usage

docker run -p 8080:8080 -p 50000:50000 wouterds/rpi-jenkins

This will store the workspace in /var/jenkins_home. All Jenkins data lives in there - including plugins and configuration. You will probably want to make that an explicit volume so you can manage it and attach to another container for upgrades :

docker run -p 8080:8080 -p 50000:50000 -v jenkins:/var/jenkins_home wouterds/rpi-jenkins

this will automatically create a 'jenkins' volume on docker host, that will survive container stop/restart/deletion.

This image is available on GitHub & DockerHub.

rpi-jenkins's Issues

This docker image (wouterds/rpi-jenkins) is not working on my Raspberry PI 4 8gb

I am trying to run this on my Raspberry PI 4 (8gb) and after starting, I can add the admin password from the logs and then click on Install suggested plugins and then it gives an error page with the text An error occurred during installation: No such plugin: cloudbees-folder'. In the logs I can find the following error (already present in the logs before adding the admin password):

SEVERE: ERROR: Signature verification failed in update site 'default' (show details)

I also tried building the Docker image myself, using the Docker file from Github, but that fails on the line:

RUN ["cross-build-start"]

and also does not get me any further in running a working Jenkins server on my Raspberry PI (running Ubuntu 22.04).

Weirdly enough, the official jenkins/jenkins:lts (version in the webpage: 2.375.3) works fine on the Raspberry PI. However, I am trying to build upon the Jenkins docker image to provide some Docker in Docker funtionality and that will not work because the needed dependencies for that cannot be found
