Packer has built-in support for using various configuration management tools like Ansible, Chef, and Puppet along with Shell and PowerShell script support for installing software.Packer uses JSON files to build the components which are simple commands and can be easily integrated with CI/CD pipelines.Packer is simple in terms of logging and debugging as the output is clearly shown in the command-line when the image is built.Packer allows you to build images for multiple platforms like AWS, Azure, GCP, Docker, etc.We will use Hashicorp’s Packer to create our Golden AMI. There are various tools available for building the golden AMIs and some of the most used ones are The block devices that specify the root device volume to attach to the EC2 instance once it’s launched.Set up permissions that control which Amazon Web Services (AWS) accounts can use the machine images to spin up an instance.A template for the instance’s root device volume.AMIs provide the information required to launch an Amazon EC2 instance, which is a virtual server in the AWS Cloud. AMI types are categorized according to region, operating system, system architecture (32- or 64-bit), launch permissions, and whether they are backed by Amazon EBS or backed by the instance store. The machine images are like templates that are configured with an operating system and other software, which determines the user’s operating system. An Amazon Machine Image (AMI) is a master image for the creation of virtual servers in an AWS environment.
