  ami           = "ami-123456"
  instance_type = "t2.micro"

  lifecycle {
    ignore_changes = [[1]]

Common Mistakes

Ignoring the wrong attribute like 'ami' or 'instance_type'.

Not using quotes around the attribute name.

The ignore_changes lifecycle rule is used to tell Terraform to ignore changes to specific attributes. Here, we want to ignore changes to the tags attribute.

medium

Complete the code to ignore changes to both 'user_data' and 'tags' attributes in the lifecycle block.

Terraform

resource "aws_instance" "example" {
  ami           = "ami-123456"
  instance_type = "t2.micro"
  user_data     = "#!/bin/bash"

  lifecycle {
    ignore_changes = [[1]]
  }
}

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

A["id", "tags"]

B["user_data"]

C["ami", "instance_type"]

D["user_data", "tags"]

💡 Hint

Common Mistakes

Not using a list for multiple attributes.

Including attributes that should not be ignored.

To ignore changes to multiple attributes, list them inside square brackets as strings. Here, both user_data and tags are ignored.

hard

Fix the error in the lifecycle block to properly ignore changes to the 'security_groups' attribute.

Terraform

resource "aws_instance" "example" {
  ami             = "ami-123456"
  instance_type   = "t2.micro"
  security_groups = ["sg-12345"]

  lifecycle {
    ignore_changes = [1]
  }
}

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

A"security_groups"

B["security_groups"]

Csecurity_groups

D[security_groups]

💡 Hint

Common Mistakes

Using a string without brackets.

Using a variable name without quotes.

Using brackets without quotes.

The ignore_changes attribute expects a list of attribute names as strings. So, it should be a list with the attribute name in quotes.

4fill in blank

hard

Fill both blanks to ignore changes to 'tags' and 'user_data' attributes in the lifecycle block.

Terraform

resource "aws_instance" "example" {
  ami           = "ami-123456"
  instance_type = "t2.micro"
  user_data     = "#!/bin/bash"

  lifecycle {
    ignore_changes = [[1], [2]]
  }
}

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

A"tags"

B"ami"

C"user_data"

D"instance_type"

💡 Hint

Common Mistakes

Using wrong attribute names like 'ami' or 'instance_type'.

Not quoting the attribute names.

To ignore multiple attributes, list each attribute name as a string inside the list. Here, 'tags' and 'user_data' are ignored.

5fill in blank

hard

Fill all three blanks to ignore changes to 'tags', 'user_data', and 'security_groups' attributes in the lifecycle block.

Terraform

resource "aws_instance" "example" {
  ami             = "ami-123456"
  instance_type   = "t2.micro"
  user_data       = "#!/bin/bash"
  security_groups = ["sg-12345"]

  lifecycle {
    ignore_changes = [[1], [2], [3]]
  }
}

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

💡 Hint

Common Mistakes

Including attributes that should not be ignored like 'ami'.
