Which Terraform command is used to create an execution plan?

The command used to create an execution plan in Terraform is "terraform plan." This command evaluates the current state of resources, compares it to the configuration files that define the desired state, and shows which changes will be made when applying those configurations. The "terraform plan" command helps users to review the proposed changes before actually applying them, which reduces the risk of unintended modifications to infrastructure.

This command outputs a detailed list of actions that Terraform will take, including any resources to be created, modified, or destroyed based on the current configuration and state. By reviewing this execution plan, users can ensure that they understand the ramifications of the changes that will be applied and can avoid potential errors or misconfigurations.

The other commands serve different purposes: "terraform apply" directly applies the configurations and changes, "terraform init" initializes a working directory containing Terraform configuration files by setting up the backend and downloading required provider plugins, and "terraform import" is used to import existing infrastructure into Terraform management. Thus, these commands do not focus on creating an execution plan the way "terraform plan" does.
