Setup Cloud CI in 15 minutes with Jenkins, DotCi, Docker and DigitalOcean

• Create a droplet with docker under applications

• Install mongodb and jenkins trusted docker builds

 mkdir -p /mongodb/db 
 docker run -d -p 27017:27017 -v /mongodb:/data --name mongodb library/mongo

 docker run -d -P -p 80:8080 --link mongodb:mongodb -v /jenkins:/jenkins aespinosa/jenkins

• Install DotCi: You should now be able to access your jenkins instance at http://<droplets-ip-address> . Install DotCi plugin from Jenkins update center by going to Manage Jenkins > Manage Plugins

• Create a github application with Authorization callback URL of http://<droplets-ip-address>/dotci/finishLogin

• Configure github-oauth-plugin Manage Jenkins > Configure Global Security

• Add jenkins slave. Jenkins master is the docker container running jenkins. We don't want builds running on master, but you can add the same droplet as a jenkins slave .

  • Make sure you to add ssh keys of your machine to your github account. Github guide describing the process.

• Install git and java on the machine with

 apt-get update && apt-get install -q -y openjdk-7-jre-headless git

• Add droplet as a jenkins slave under Manage Jenkins > Manage Nodes. Add root username and password credentials emailed to you when you created the droplet.

• Configure DotCi: Under Manage Jenkins > Configure System change mongodb host from localhost to mongodb and label to docker
