cantara/jenkins repository overview

⁠Jenkins continuous integration server

Goal: Simplify installation and configuration of Jenkins for Java development.

See https://github.com/jenkinsci/docker⁠ for tips, most of it is applicable to this fork as well.

Data is stored in a Data Volume Container. Latest Maven 3, Zulu JDK 8 and a few of the most useful plugins are preinstalled.
Jenkins Core: 1.609.3 (latest LTS), see http://jenkins-ci.org/changelog#stable⁠
List of plugins: https://raw.githubusercontent.com/Cantara/maven-infrastructure/master/jenkins/plugins.txt⁠
Webproxy (incl. TLS termination) is considered out of scope. Recommend using a separate docker container which links to this container.
- https://docs.docker.com/userguide/dockerlinks/⁠

⁠Install and use

⁠Install or upgrade Docker

https://docs.docker.com/installation/ubuntulinux/⁠

wget -qO- https://get.docker.com/ | sh

⁠Install data volume container and jenkins

sudo docker pull cantara/jenkins
sudo docker create -v /var/jenkins_home --name jenkins-data cantara/jenkins
sudo docker run -d -p 8080:8080 --volumes-from jenkins-data --name jenkins20150715 cantara/jenkins

⁠Initial Jenkins config, point your browser to http://localhost:8080/⁠

Use jenkins to setup security and users

https://wiki.jenkins-ci.org/display/JENKINS/Standard+Security+Setup⁠

Update plugins, http://localhost:8080/pluginManager/⁠
Set up CI user with access to git/github repositories

Create SSH keys: https://developer.github.com/guides/managing-deploy-keys/#machine-users⁠
Add SSH private key to Jenkins, http://localhost:8080/credentials/⁠

Setup settings.xml to give Jenkins access to non-public Maven repos

Add settings.xml, http://localhost:8080/configfiles/⁠
Remember to reference the settings.xml file in the build configuration for the Maven project.

⁠Backup

See https://docs.docker.com/userguide/dockervolumes/#backup-restore-or-migrate-data-volumes⁠

⁠Development

⁠TODO

Transitive plugin dependencies are not installed automatically and plugins are not updated to latest version. Perhaps this script https://gist.github.com/micw/e80d739c6099078ce0f3⁠ can fix one or both problems?

⁠Build and run for development

sudo docker build -t cantara/jenkins .
sudo docker create -v /var/jenkins_home --name jenkins-data cantara/jenkins
sudo docker run -d -p 8080:8080 --volumes-from jenkins-data --name jenkins20150515 cantara/jenkins

To stop and remove all containers:

docker stop $(docker ps -a -q) && docker rm $(docker ps -a -q)

To log in to take a look:

docker ps -a
docker exec -it containerIdHere bash

⁠Decisions

Public git repo here: https://github.com/Cantara/maven-infrastructure⁠
Dockerhub image built from source: cantara/jenkins
Decided to use Data Volume Container
Copied from https://github.com/jenkinsci/docker⁠, instead of using FROM jenkins because the published image used openjdk7.
Copied from https://github.com/docker-library/java/blob/b4a3c296023e590e410f645ab83d3c11a30cf535/openjdk-8-jdk/Dockerfile⁠ and switch to Zulu from OpenJDK
Install Maven using apt and update Jenkins config to reference it, hudson.tasks.Maven.xml.
Update Jenkins config to reference JDK installation, config.xml.
Install plugins usually used in Maven/Java projects.

⁠Plugins

Maintain a list of plugins here to find plugin key, version and description of what it does.
