14.Provision IAM User with Terraform

The DevOps team is experimenting with Terraform provisioners to create an IAM user. The goal is to create an IAM user named "iamuser_siva" using Terraform. A local-exec provisioner will be used alongside the IAM user resource. This provisioner is responsible for logging a specific confirmation message to a log file. The lab requires creating a `variables.tf` file to define a variable for the IAM user's name. The `terraform.tfvars` file is used to assign a value to this variable. The `main.tf` file defines the IAM user resource and the local-exec provisioner. The `outputs.tf` file is used to output the IAM user's name after creation. Terraform commands such as `terraform init`, `terraform validate`, and `terraform apply` are executed in sequence. The local-exec provisioner runs a command to echo a specific confirmation message to a file. The expected result includes a successful creation of the user and the logged message. The lab emphasizes the use of variables and the correct path for the log file. The local-exec runs on the machine running Terraform, not within AWS. The log file confirms the successful IAM user creation.
