Update README.md
The Jenkins Continuous Integration and Delivery server.
This is a fully functional Jenkins server, based on the Long Term Support release http://jenkins-ci.org/
docker run -p 8080:8080 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 a persistent volume (recommended):
docker run -p 8080:8080 -v /your/home:/var/jenkins_home jenkins
This will store the jenkins data in /your/home on the host. Ensure that /your/home is accessible by the jenkins user in container (jenkins user - uid 102 normally - or use -u root).
You can also use a volume container:
docker run --name myjenkins -p 8080:8080 -v /var/jenkins_home jenkins
Then myjenkins container has the volume (please do read about docker volume handling to find out more).
If you bind mount in a volume - you can simply back up that directory (which is jenkins_home) at any time.
This is highly recommended. Treat the jenkins_home directory as you would a database - in Docker you would generally put a database on a volume.
If your volume is inside a container - you can use docker cp $ID:/var/jenkins_home
command to extract the data. Note that some symlinks on some OSes may be converted to copies (this can confuse jenkins with lastStableBuild links etc)
You can run builds on the master (out of the box) buf if you want to attach build slave servers: make sure you map the port: -p 50000:50000
- which will be used when you connect a slave agent.
Here is an example docker container you can use as a build server with lots of good tools installed - which is well worth trying.
You can run your container as root - and unstall via apt-get, install as part of build steps via jenkins tool installers, or you can create your own Dockerfile that has FROM jenkins
at the top and add in any dependencies you may need.
All the data needed is in the /var/jenkins_home directory - so depending on how you manage that - depends on how you upgrade. Generally - you can copy it out - and then "docker pull" the image again - and you will have the latest LTS - you can then start up with -v pointing to that data (/var/jenkins_home) and everything will be as you left it.
As always - please ensure that you know how to drive docker - especially volume handling!
