💡 Hint

Common Mistakes

Using local commands like 'terraform apply' which run on your machine, not remotely.

Forgetting to put the command inside quotes.

The inline block runs commands on the remote instance. Here, echo Hello, World! is a simple command to run.

Complete the code to specify the connection type for the remote-exec provisioner.

Terraform

connection {
  type     = "[1]"
  user     = "ubuntu"
  private_key = file("~/.ssh/id_rsa")
  host     = self.public_ip
}

💡 Hint

Common Mistakes

Using 'winrm' for Linux instances.

Using HTTP or HTTPS which are not connection types for remote-exec.

The connection block defines how Terraform connects to the instance. For Linux instances, ssh is used.

Fix the error in the provisioner block to correctly run multiple commands remotely.

  inline = ["sudo apt-get update", [1]]
}

💡 Hint

Common Mistakes

Not quoting commands inside the inline list.

Mixing quoted and unquoted commands.

Commands in the inline list must be strings inside quotes. Option A correctly quotes the command.

4fill in blank

hard

Fill both blanks to define a remote-exec provisioner that runs a command and uses SSH connection with a specific user.

Terraform

connection {
  type     = "[1]"
  user     = "[2]"
  private_key = file("~/.ssh/id_rsa")
  host     = self.public_ip
}

provisioner "remote-exec" {
  inline = ["sudo systemctl restart nginx"]
}

💡 Hint

Common Mistakes

Using 'winrm' connection type for Linux instances.

Using 'admin' as user instead of 'ubuntu'.

The connection type for Linux instances is ssh, and the default user for Ubuntu instances is ubuntu.

5fill in blank

hard

Fill all three blanks to create a remote-exec provisioner that runs a command, uses SSH connection, and specifies the host.

Terraform

connection {
  type        = "[1]"
  user        = "[2]"
  private_key = file("~/.ssh/id_rsa")
  host        = [3]
}

provisioner "remote-exec" {
  inline = ["sudo apt-get install -y nginx"]
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 'winrm' for Linux instances.

Not referencing the host correctly.

Using wrong user names.

Use ssh as connection type, ubuntu as user, and self.public_ip to specify the instance's public IP address.
