This template allows you to do blue/green deployment to a VMSS cluster using Jenkins. It provisions a Jenkins master on a VM running on Azure, configures a DevOps pipeline to bake a managed OS image with Tomcat 7 or 8 installed and deploys it to the VMSS. It is an example to demonstrate how we can use Jenkins pipeline to do blue/green deployment on VMSS.
