Terraform is a popular infrastructure-as-code tool that automates the provisioning and management of infrastructure resources.

Find the purpose of basic Terraform commands that you'll use often

We’ve created a main.tf file on our ec2 instance.

resource “local_file” “devops” {
 filename = “/home/ubuntu/terraform/first_file.txt”
 content = “this is my file”
}

terraform init

In order to prepare the working directory for use with Terraform, the terraform init command performs Backend Initialization, Child Module Installation, and Plugin Installation.

2) terraform init -upgrade

Performs the same initialization as terraform init but also upgrades installed provider plugins to their latest versions.

3) terraform plan

Plan will generate an execution plan, showing you what actions will be taken without actually performing the planned actions.

4) terraform apply

Create or update infrastructure depending on the configuration files. By default, a plan will be generated first and will need to be approved before it is applied.

We have applied the terraform, Let’s check if the file is created in our directory.

Our file has been created successfully.

5) terraform validate

Validate the configuration files in your directory and does not access any remote state or services. terraform init should be run before this command.
