jenkins-ist

Github repo for automated builds of a custom version of Jenkins on docker hub.

Installation

1. Ensure /data/jenkins/ directory is created and has the correct permissions.

• If you are using vagrant, the directory should be owned by vagrant. If you are logged in to an Ubuntu EC2 instance, then the ubuntu user should own the directory.
• If it needs to be created:
  1. Run sudo mkdir /data
  2. Run sudo mkdir /data/jenkins
  3. Run sudo chown 1000 /data/jenkins

2. Build the Jenkins docker image that you want to run in a container. Ensure you are in the /jenkins directory with the Dockerfile and run docker build -t ist/jenkins:[Version] .
3. To run the container: docker run -d --name jenkins[Version] --net=host -p 8080:8080 -p 5000:5000 -v /data/jenkins:/var/jenkins_home -u 1000 -t ist/jenkins:[Version]

• -d to run in the background
• --net=host so the container shares the host network stack and has access to the /etc/hosts for network communication
• -p 8080:8080 so the 8080 port in the container receives all requests to port 8080 on the host. Jenkins runs on Tomcat, which uses port 8080 as the default
• -p 5000:5000 required to attach slave servers; port 50000 is used to communicate between master and slaves
• -v /data/jenkins:/var/jenkins_home to bind host directory /data/jenkins to the container directory /var/jennkins_home
• -u 1000 jenkins user uid is 1000, same as ubuntu and vagrant uid's are 1000
