How to setup the Jenkins master¶
Table of Contents
I used this SO answer to setup a subdomain to a port:
I had to remove the
hudson in each of the lines that contained it.
We renamed some of the jobs, so I added rewrite rules in Apache (

- Shell into the master (
/var/lib/jenkins/.ssh/id_rsa.puband paste it into
/home/jenkins/.ssh/authorized_keyson the new machine.
- Copy config from the
linux 2machine, rename and otherwise modify as needed (e.g., change the IP/host).
/etc/ssh/ssh_host_rsa_key.pubfrom the new machine and add it as an entry in
/var/lib/jenkins/.ssh/known_hosts(with the new machine’s IP) on the master, then re-hash that file on the master:
First I updated all the preinstalled plugins.
Then I setup authentication with the
I just installed it and followed their setup instructions:
I created an application entry on the ros2 GitHub organization:
I also tuned the permissions in
Manage Jenkins->Configure Global Security.
Next I installed all of these plugins:
github(other git* plugins are deps of the
Jenkins needs a valid ssh key in order to pull from some of our private repositories, for example to get the rti deb files.
So I created an ssh key for the jenkins user on the webserver:
sudo su jenkins cd mkdir .ssh ssh-keygen -t rsa
Then I added to the jenkins credentials as an “From the jenkins master ~/.ssh” with the user id of
I added this key to a “machine” GitHub account that I created for this farm and I added that user,
ros2-buildfarm, to the
I cloned the
ros2/ci repository to the default branch (
git clone https://github.com/ros2/ci.git
Then I cloned the
git clone https://github.com/ros-infrastructure/ros_buildfarm.git
I also install the
EmPy Python packages:
sudo apt install python3-pip sudo -H python3 -m pip install -U pip sudo -H python3 -m pip install jenkinsapi EmPy
Then I setup auth:
mkdir -p ~/.buildfarm vim ~/.buildfarm/jenkins.ini
Put this in the
[http://ci.ros2.org] username=wjwwood password=<your application token>
Now, you should first login with GitHub on Jenkins if you haven’t already. Then put your github username in and for the application token, browse to the configuration of your user on Jenkins:
In those settings there should be a field called API Token. Copy that field for your password.
Now I can create the jobs:
$ PYTHONPATH=`pwd`/../ros_buildfarm ./create_jenkins_job.py -u http://ci.ros2.org Connecting to Jenkins 'http://ci.ros2.org' Connected to Jenkins version '1.617' Creating job 'ros2_batch_ci_windows' The Jenkins master does not require a crumb Creating job 'ros2_batch_ci_osx' Creating job 'ros2_batch_ci_linux' Creating job 'ros2_batch_ci_launcher'
The final step is to fine tune the jobs. For each job you’ll want to check the ssh key being used for the git clone (only on Linux) and the ssh-agent. It should be set to the ssh key setup in the previous steps for the jenkins user.
I also updated the slaves which the jobs will run on to make sure they matched the names of the slaves I added for Linux, OS X and Windows.
