1.0 Jenkins Overview
Jenkins is a continuous integration (CI) server that supports a wide range of tools and technologies. Adopting a CI process ensures that all developers' working copies of code are regularly merged into a shared trunk. Once a change is committed to the repository, the product is automatically rebuilt and tested.
With Jenkins you can automate a number of day-to-day tasks such as checking out the sources from source control, building, code analysis, and different levels of testing and deployment.
By setting up Jenkins to run these tasks each time a developer has changed the source code, you can detect any defects much faster meaning that you maintain your applications' quality and reduce time to market.
Jenkins is highly configurable, and there are numerous plugins available that provide access to a range of tools including source control, shell and batch scripts. Jenkins works on multiple platforms, supports Java and integrates with other corporate systems.

Be sure to use large Virtual Machines and add extra disk as needed.
2.0 Deploying Jenkins
Now let's begin with the fun part!
Check the plan and click in "CREATE"
Follow the process of creating the Azure virtual machine.
After finishing creation, you can connect using ssh or by console.
To connect using the console, just access http://yourvmIP:8080
You can also connect using the ssh command line. For more information, see How to use SSH with Linux on Azure.
Setting up Jenkins
To set up your installation, visit Jenkins on its default port, 8080, using your server domain name or IP address: http://yourvmIP:8080
You should receive the Unlock Jenkins page:

Finally, after customizing Jenkins with plugins, Jenkins asks you to create your first administrator user.
When the Create First Admin User page appears, specify the details for your administrator user in the respective fields and click Save and Finish.
After finishing the settings, you should receive a message that your Jenkins is ready!
Congratulations, you made it! now just enjoy your Jenkins! :)
