If not, follow the steps below before continuing.Ĭreate a directory named packer_tutorial and paste the following configuration into a file named. This tutorial assumes that you are continuing from the previous tutorials. In this tutorial, you will build a second Docker image in parallel.While the second image is a Docker image for the sake of this tutorial, the second source could just as easily come from another hypervisor or a cloud platform.
#DOCKER PARALLELS VS VMWARE SOFTWARE#
Or, another example, if you're using Packer to build software appliances, then you can build the appliance for every supported platform all in parallel and configured from a single template. The AMI can be used for production, the VMware machine can be used for development. For example, Packer can build an Amazon AMI and a VMware virtual machine in parallel provisioned with the same scripts, resulting in near-identical images. Parellel build is a very useful and important feature of Packer. While this is already quite powerful, Packer can create multiple images in parallel, all configured from a single template. Then, you parameterized the template allowing you to build different images using the same template. In the previous tutorials, you used Packer to automatically build an image and provision it from a template.
