Packer CLI is a powerful command-line interface used to automate the creation of machine images across multiple platforms. It simplifies the process of building, managing, and deploying machine images, whether for cloud environments, virtual machines, or containers. Packer CLI is an essential tool for DevOps workflows, infrastructure automation, and continuous integration/continuous delivery (CI/CD) pipelines.

Features of Packer CLI:

• Automates the creation of machine images across different platforms (AWS, Azure, Google Cloud, VMware, Docker, etc.).
• Customizable workflows for defining and building images using configuration files.
• Ability to use various provisioners like Shell, Ansible, Chef, and Puppet to configure machines during the build process.
• Parallel image building, saving time by creating multiple images simultaneously.
• Support for multiple image formats, making it easier to deploy to different environments.
• Integration with cloud platforms for building, testing, and deploying images directly to cloud environments.
• Can be integrated with other tools like Terraform for infrastructure as code and CI/CD pipelines.

Run these commands:
$ packer build
$ packer --version
