Terraform Plan

You can establish an execution plan for your Terraform configurations using the ‘terraform plan’ command. It examines the desired state specified in your configuration files, assesses it against the infrastructure’s present condition, and produces a thorough report of the suggested adjustments. This command is quite helpful for figuring out how changes to your infrastructure will affect things and for seeing any potential problems before making such changes.

Terraform Plan Syntax

The basic syntax for running the 'terraform plan' the command is as follows:

terraform plan [options] [DIR]

• [options]: This is an optional command-line flag that we can use with the terraform plan command.
• [DIR]: This optional directory path contains all the Terraform configuration files. If nothing is specified, by default it considers it to be the current directory.

When we talk about an open-source infrastructure as a code (IaC) tool Terraform automatically comes into the picture. Terraform allows declarative definition and provisioning of infrastructure resources. The Terraform command-line interface (CLI) allows you to establish and maintain your infrastructure across several cloud providers after defining it using a straightforward and legible configuration language. ‘terraform plan’ is one of the primary commands in the workflow. You can preview the adjustments Terraform will make to your infrastructure using the ‘terraform plan’ command before actually implementing those adjustments. To further understand the ‘terraform plan’ command’s significance in infrastructure design, we shall examine it in-depth in this article and offer real-world examples.
