Infrastructure as code (IaC) is a standard practice of maintaining infrastructure configuration as code. Terraform is a cross-platform tool that introduces the HashiCorp Configuration Language (HCL) for the provisioning of infrastructures on different cloud platforms like Azure, AWS, and Google Cloud.

First you’ll learn about the basics of IaC and the tools used for it. Next, you’ll learn about Terraform, how to deploy resources using it, and the Terraform state file. Then you’ll cover the basics of HCL, followed by how to work with outputs, expressions, and loops. You’ll also cover local and remote provisioners, and learn how to employ HCL to provision and manage resources using different concepts like modules, variables, provisioners, and the Terraform state file. Finally, you’ll learn how to use the Terraform Cloud.

By the end of this course, you’ll be able to provision, delete, and update resources on a cloud platform using Terraform. Knowing how to use Terraform effectively will set you up for success.

Terraform provisioners can *not* be used for which purpose?

Terraform provisioners can not be used for which purpose?

**(True or False)** A `local-exec` provisioner can be used to run commands on a remote server.

(True or False) A <code>local-exec</code> provisioner can be used to run commands on a remote server.

```
resource "aws_instance" "my_vm" {
 ami           = var.ami //Amazon Linux AMI
 instance_type = var.instance_type
 
 provisioner "local-exec" {
   command = "echo ${private_ip} >> file.txt"
 }
 
 tags = {
   Name = var.name_tag,
 }
}
```

```
resource "aws_instance" "my_vm" {
 ami           = var.ami //Amazon Linux AMI
 instance_type = var.instance_type
 
 provisioner "local-exec" {
   command = "echo ${self.private_ip} >> file.txt"
 }
 
 tags = {
   Name = var.name_tag,
 }
}
```

```
resource "aws_instance" "my_vm" {
 ami           = var.ami //Amazon Linux AMI
 instance_type = var.instance_type
 
 provisioner "local-exec" {
   command = "${self.private_ip} >> file.txt"
 }
 
 tags = {
   Name = var.name_tag,
 }
}
```

```
resource "aws_instance" "my_vm" {
 ami           = var.ami //Amazon Linux AMI
 instance_type = var.instance_type
 
 provisioner {
   command = "echo ${self.private_ip} >> file.txt"
 }
 
 tags = {
   Name = var.name_tag,
 }
}
```

Which code block can be used to fetch the IP address of an EC2 instance into a file named `file.txt`?

Which code block can be used to fetch the IP address of an EC2 instance into a file named <code>file.txt</code>?

Which parameter in the `remote-exec` provisioner block can be used to pass the SSH private key for authenticating to the remote host?

Which parameter in the <code>remote-exec</code> provisioner block can be used to pass the SSH private key for authenticating to the remote host?

```plain
resource "aws_instance" "my_instance" {
  ami           = "ami-1111111111"
  instance_type = "t2.micro"

  provisioner "local-exec" {
    command = "echo Hello, World!"
  }
}
```

```plain
resource "aws_instance" "my_instance" {
  ami           = "ami-1111111111"
  instance_type = "t2.micro"

  provisioner "remote-exec" {
    script = "script.sh"
  }
}
```

```
resource "aws_instance" "my_instance" {
  ami           = "ami-1111111111"
  instance_type = "t2.micro"

  provisioner "file" {
    source = "script.sh"
    destination = "/tmp/script.sh"
  }
}
```

```plain
resource "aws_instance" "my_instance" {
  ami           = "ami-1111111111"
  instance_type = "t2.micro"

  provisioner "remote-exec" {
    file = "script.sh"
  }
}
```
