docker-jenkins

Sets up a container with jenkins installed listening on port 8080. This fork also includes git. This setup is a bit opinionated and will probably become moreso over time

Usage

To run the container, do the following:

docker run -d -P --name jenkins anichols/jenkins

docker ps
CONTAINER ID        IMAGE                       COMMAND                CREATED             STATUS              PORTS                     NAMES
1131d37c38b1        anichols/jenkins:latest    java -jar /opt/jenki   12 seconds ago      Up 12 seconds       0.0.0.0:49153->8080/tcp   drunk_fermi

Your jenkins instance is now available by going to http://localhost:49153

Generally you'll want Jenkins bound to a static port so you can run with -p 8080:8080 for example to always run on port 8080

Data persistence

By default this is a basic Jenkins installation which doesn't contain many plugins. It is strongly recommended that you setup a persistent data volume for Jenkins so that you can upgrade this container and maintain your existing Jenkins configurations & plugins. The easiest way to do this is to bind mount the directory /jenkins inside the container to a directory on the Docker host.

mkdir -p /docker-jenkins

docker run -d -p 8080:8080 -v '/docker-jenkins:/jenkins' --name jenkins
anichols/jenkins

This will persist all Jenkins configurations & plugins in a directory named /docker-jenkins on the Docker host. You can backup this directory if you choose or use one of the Jenkins backup plugins.

Java tuning

You may pass java arguments using the JAVA_OPTS environment variable. This is optional, but if you need to tune memory parameters you can do so:

docker run -e 'JAVA_OPTS="-Xmx=512m,-Xms=256m"' anichols/jenkins

Jenkins management

This fork should allow jenkins to properly restart inside the container however if you want to stop/restart the container you can do so using docker:

To Stop: docker stop jenkins

To Restart: docker restart jenkins

To view Jenkins logs: docker logs jenkins

Container upgrades

If you persist your Jenkins configuration on a volume outside the docker container then you can upgrade the container without losing any of your plugins/configuration. If you did not map your /jenkins directory to a persistent volume then this upgrade process will DESTROY all your Jenkins configurations & plugins.

If you want to upgrade the container it should be pretty simple:

docker stop jenkins
docker rm jenkins
docker pull anichols/jenkins
docker run -d -p 8080:8080 -v '/docker-jenkins:/jenkins' --name jenkins
anichols/jenkins

Building

To build the image, simply invoke

docker build github.com/adnichols/docker-jenkins

A prebuilt container is also available in the docker index

docker pull anichols/jenkins
