This document is specific to the London RedCentric lab, but should evolve to a more generic setup once we have more labs. For now, there are some hard-coded logic in the wiki as well as the scripts, to make sure we can reproduce at least the one lab we have. Once we have more labs, we'll work to automate that using configuration files, command line options, etc.

...

root@hpc-admin # cd ~/labconf/ans_setup_mrp/
root@hpc-admin # ./pre-setup.sh
root@hpc-admin # ansible-playbook mrp_setup.yml -vvvv -u root

Ansible will start MrProvisioner automatically, so you should be able to just open the URL on your browser (assuming you have a route to the machine's IP):

...

root@hpc-admin # cd ~/labconf/ans_setup_jenkins
root@hpc-admin # ansible-playbook configure-jenkins.yml -vvvv -u root

Ansible will start Jenkins automatically, so you should be able to just open the URL on your browser (assuming you have a route to the machine's IP):

...

You may get two warnings when you log in to Jenkins, which can be corrected on the Global Security screen:

• ERROR in config.xml: Jenkins may complain "version 1.1" is not supported, only 1.0. Editing /var/lib/jenkins/config.xml and changing that on the first line seems to work.
• Agent to master security subsystem is currently off: Go to Security Settings and check the box saying "Enable Agent → Master Access Control"
• Jenkins instance uses deprecated protocols: JNLP3-connect: Go to Security Settings > Agents and clear the box "Java Web Start Agent Protocol/3" in "Agent Protocols"
  

Themes: Install the Simple Theme Plugin and choose one from the list by updating the theme URL in the general settings.

Save the configuration and you should be all set.

Installing the Jenkins Jobs

...

root@hpc-admin # ansible-playbook -vvvv -u root jenkins.yml

This also works to update once there are changed. This playbook will create the nodes, jobs, users, ssh keys, etc.

...

root@hpc-admin # ansible-playbouok -vvvv -u root mrp.yml
root@hpc-admin # ansible-playbouok -vvvv -u root fs.yml

Updating Jenkins Jobs

Once the jobs are installed and working, on every change pertaining the Jenkins configuration, you just need to update the repo and run the same playbook again:

root@hpc-admin # cd hpc_lab_jenkins
root@hpc-admin # git fetch -a & git pull
root@hpc-admin # ansible-playbook -vvvv -u root jenkins.yml
