This GitHub repository contains Dockerfiles for running a set of Continuous Integration Tools with a single command. The diagram contains all tools used in the Docker containers.
Blog article on the CI Docker Container, https://blog.codecentric.de/en/2015/10/continuous-integration-platform-using-docker-container-jenkins-sonarqube-nexus-gitlab
You should have Docker Toolbox installed, see https://www.docker.com/toolbox
I am using docker-compose to start several docker container at once. Since all containers run in a single VM (virtualbox), this VM needs enough memory.
Ensure that you are using version 0.3.0 or greater of docker-machine
# docker-machine version
docker-machine version 0.5.4, build
Start the machine, using the --virtualbox-memory
option to increase it’s memory.
I use 6000 MB to accommodate all the docker images.
# docker-machine create -d virtualbox --virtualbox-memory "6000" default

Docker is up and running!
To see how to connect Docker to this machine, run: docker-machine env default
Configure shell environment to connect to your new Docker instance
# eval “$(docker-machine env default)”
To get all docker containers up and running use:
# git clone git@github.com:marcelbirkner/docker-ci-tool-stack.git
# cd docker-ci-tool-stack
# docker-compose up
Tool | Link | Credentials |
---|---|---|
Jenkins | http://${docker-machine ip default}:18080/ | no login required |
SonarQube | http://${docker-machine ip default}:19000/ | admin/admin |
Nexus | http://${docker-machine ip default}:18081/nexus | admin/admin123 |
GitLab | http://${docker-machine ip default}:10080/ | root/5iveL!fe |
Selenium Grid | http://${docker-machine ip default}:4444/grid/console | no login required |
Here is an overview of all tools:
- GitLab is used for storing the Source Code
- Jenkins contains build job and is triggered once projects in GitLab are updated
- As part of the CI build, Jenkins triggers a static code analysis and the results are stored in SonarQube
- The Maven build uses Nexus as a Proxy Repository for all 3rd party libs. The build artifacts are deployed to the Nexus Release Repository
- The Selenium Grid contains Docker containers running Chrome and Firefox and is used for UI tests
There are several jobs preconfigured in Jenkins. The Jobs cover the following tasks:
- Continuous Integration Build with Maven
- Unit Tests
- Static Source Analysis results are stored in SonarQube
- JaCoCo Test Coverage
- Deployment to Nexus
- Jenkins Job DSL examples
- Selenium UI Test
In order to test new versions, I prefer starting out with a blank VirtualBox image. That eliminates any side effects. Afterwards you can throw away the image.
# Create new image
docker-machine create --driver virtualbox --virtualbox-memory “6000” docker-ci-v1
# Configure shell environment
eval "$(docker-machine env docker-ci-v1)"
