Dynamically set Jenkins node

This post explains how to dynamically/programmatically set the node a Jenkins/Hudson job will run on. This is relatively easy to do statically, using the NodeLabel Parameter Plugin, but trickier to do programmatically.

There are a couple of things that attract me to CloudBees…

Spring MVC Hello World with Continuous Deployment

Oh dear, yet another ‘Hello World!’. But although the functionality is trivial, this little SpringMVC project is complete enough for me to use as a template to bootstrap more complex projects. It consists of:

• HTML/JSP client
• SpringMVC server using a Controller/Service/DAO design
• Maven for build and dependency management

This is an updated version of an older project I created, with the following enhancements:

• Added a full suite of automated tests (unit, integration and browser based)
• Added placeholders for JavaScript and images (both can be a little tricky to put in the correct place with SpringMVC)
• Incorporated into a continuous deployment environment

More details below, but you can find the full source code on this GitHub repository

(Previously I had the code deployed on a CloudBees instance at http://springmvc.shaunabram.cloudbees.net, but CloudBees have since unfortunately shut down their free tier).

Running Jenkins jobs sequentially

I am a huge fan of the Jenkins continuous integration tool, using it not just for continuous integration, but also continuous delivery, server monitoring and performance testing.

Although using Jenkins is normally a breeze, I recently had a need to run several Jenkins jobs sequentially and it proved a little trickier than expected, so I thought worth posting about.

Basically, I wanted to call a database backup job before calling the deploy build job, which obviously shouldn’t be done in parallel. After a bit of research, I found a number of ways to have Jenkins run jobs sequentially.
