Practice - 5 Tasks

easy

Complete the code to add a lifecycle rule that creates the new resource before destroying the old one.

Terraform

resource "aws_instance" "example" {
  ami           = "ami-12345678"
  instance_type = "t2.micro"

  lifecycle {
    create_before_destroy = [1]
  }
}

💡 Hint

Common Mistakes

Using string values like 'yes' or 'no' instead of boolean true/false.

Setting the value to false which disables create before destroy.

The create_before_destroy lifecycle rule must be set to true to ensure the new resource is created before the old one is destroyed.

medium

Complete the lifecycle block to ensure Terraform creates the replacement resource before destroying the current one.

Terraform

lifecycle {
  [1] = true
}

💡 Hint

Common Mistakes

Confusing with prevent_destroy which stops destruction.

Using unrelated lifecycle attributes.

The create_before_destroy attribute tells Terraform to create the new resource before destroying the old one.

Fix the error in the lifecycle block to enable create_before_destroy behavior.

Terraform

lifecycle {
  create_before_destroy = [1]
}

💡 Hint

Common Mistakes

Using quotes around boolean values causing syntax errors.

Setting the value to false disables the behavior.

The value must be a boolean true without quotes, not a string. Remove the quotes to fix the error.

4fill in blank

hard

Fill both blanks to complete the lifecycle block that creates the new resource before destroying the old one and ignores changes to tags.

Terraform

lifecycle {
  [1] = true
  [2] = ["tags"]
}

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

💡 Hint

Common Mistakes

Mixing up lifecycle attribute names.

Using incorrect values for ignoring changes.

create_before_destroy = true ensures the new resource is created first. ignore_changes = ["tags"] tells Terraform to ignore tag changes.

5fill in blank

hard

Fill all three blanks to complete the lifecycle block that creates before destroy, prevents accidental destroy, and triggers replacement when user_data changes.

Terraform

lifecycle {
  [1] = true
  [2] = true
  [3] = ["user_data"]
}

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

💡 Hint

Common Mistakes

Confusing replace_triggered_by with ignore_changes.

Forgetting to set booleans without quotes.

create_before_destroy = true creates new resource first. prevent_destroy = true stops accidental deletion. replace_triggered_by = ["user_data"] forces replacement if user_data changes.
