Provisioner failure behavior in Terraform - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the provisioner that runs a script on the resource.

Terraform

resource "null_resource" "example" {
  provisioner "[1]" {
    script = "setup.sh"
  }
}

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

Afile

Blocal-exec

Cnull

Dremote-exec

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'remote-exec' when the script should run locally.

Using 'file' provisioner instead of executing a script.

The local-exec provisioner runs a command locally on the machine running Terraform.

2fill in blank

medium

Complete the code to make Terraform continue even if the provisioner fails.

Terraform

resource "null_resource" "example" {
  provisioner "local-exec" {
    command = "exit 1"
    [1] = true
  }
}

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

Aignore_errors

Bcontinue_on_error

Cfail_on_error

Dallow_failure

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'fail_on_error' which causes Terraform to stop on failure.

Using non-existent arguments like 'continue_on_error'.

The ignore_errors argument tells Terraform to continue even if the provisioner command fails.

3fill in blank

hard

Fix the error in the provisioner block to correctly handle failure behavior.

Terraform

resource "null_resource" "example" {
  provisioner "local-exec" {
    command = "exit 1"
    ignore_errors = [1]
  }
}

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

A"true"

B1

Cyes

Dtrue

Attempts:

3 left

💡 Hint

Common Mistakes

Using quotes around true, which makes it a string.

Using numbers or words like 'yes' instead of boolean.

The ignore_errors argument expects a boolean value true or false, not a string or number.

4fill in blank

hard

Fill both blanks to configure a remote-exec provisioner that retries on failure.

Terraform

resource "null_resource" "example" {
  provisioner "remote-exec" {
    inline = ["echo Hello"]
    [1] = 3
    [2] = 10
  }
}

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

Amax_retries

Bretry_delay_sec

Cretry_delay

Dmax_attempts

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'max_attempts' which is not a valid argument.

Using 'retry_delay' without '_sec' suffix.

max_retries sets how many times Terraform retries the provisioner on failure, and retry_delay_sec sets the delay in seconds between retries.

5fill in blank

hard

Fill all three blanks to define a provisioner that uploads a file and ignores failure.

Terraform

resource "null_resource" "example" {
  provisioner "file" {
    source      = "app.zip"
    destination = "/tmp/app.zip"
    [1] = "ubuntu"
    [2] = "/home/ubuntu/.ssh/id_rsa"
    [3] = true
  }
}

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

Auser

Bprivate_key

Cignore_errors

Dusername

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'username' instead of 'user' which is the correct argument.

Not setting 'ignore_errors' to true to allow continuation on failure.

The user specifies the SSH user, private_key specifies the SSH key path, and ignore_errors allows Terraform to continue if the provisioner fails.
