Want to quickly setup Jenkins on the cloud? Try this on http://www.nitrous.io. See a prior post about setting up Dashing.io on Nitrous.io for basics of how to get started on Nitrous.io if required and then come back here. Advantage: If you want to experiment with something new on Jenkins before you run it in a production environment, this will get you going quickly. If you mess up, just re-install in Nitrous.io and start over. Step 1:  Copy the installation commands from this Jenkins-ci page - https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu to a shell script in the Nitrous.io IDE and run the shell script. You could just run them in the command line if you choose. Step 2:  View Jenkins in the browser by previewing port 8080 as seen in the screenshot Jenkins will show up on a new browser window. It works! 

Most puppet modules can be designed to support multiple operating systems. Puppet has built in features to allow this through some simple syntax in the .pp file. It is a good practice to do that, whether you are publishing these modules on Puppet Forge or building highly customized modules for a specific purposes in a private enterprise. 1. Scalability - In case an organization chooses to switch operating systems or support other operating systems, your modules are already supporting them or they already have some operating systems and it is a matter of adding a few lines of code at the very top to add support for other operating systems. 2. Visibility and usability - The modules that support more than one operating system have higher usage counts on Puppet Forge because they support more than one type of need. We will walk through a simple example to demonstrate multi-OS support. I checked in this code in GitHub at https://github.com/adityai/puppetApache . Module: Install Apac...
