Description: The ‘Plan File’ in Terraform is a file generated by the ‘terraform plan’ command, which contains a detailed summary of the actions Terraform will take to achieve the desired state of the infrastructure defined in the configuration files. This file acts as an execution plan, allowing users to review and validate proposed changes before applying them. The plan file includes information about the creation, modification, or deletion of resources, as well as any dependencies between them. Its format is binary and is designed to be used by Terraform, meaning it is not directly human-readable. Generating this file is a best practice, as it provides an additional layer of security and control, allowing teams to anticipate the impact of their changes on the infrastructure. Furthermore, the plan file can be stored and shared, facilitating collaboration and change review in team environments.
