💡 Hint

Common Mistakes

Using private_ip instead of public_ip when external access is needed.

Using resource id or arn which are not IP addresses.

The output value should be the public IP of the instance to expose it.

Complete the code to declare an output named "bucket_name" that shows the S3 bucket's name.

Terraform

output "bucket_name" {
  value = [1]

Attempts:

💡 Hint

Common Mistakes

Using arn or id instead of the bucket name.

Using region which is unrelated to the bucket's name.

The bucket attribute "bucket" holds the bucket's name, which is what we want to output.

💡 Hint

Common Mistakes

Using "instance_id" which is not a valid attribute.

Using "instance" which is the resource name, not an attribute.

The correct attribute to get the instance ID is "id".

💡 Hint

Common Mistakes

Using wrong resource name like "db" instead of "mydb".

Using "endpoint" attribute which is not valid; use "address".

The resource is "aws_db_instance.mydb" and the attribute for the endpoint address is "address".

5fill in blank

hard

Fill all three blanks to declare an output named "web_url" that outputs the URL combining protocol and instance public IP.

Terraform

}

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

Aaws_instance.web

C80

Dprivate_ip

Attempts:

💡 Hint

Common Mistakes

Using private_ip instead of public_ip which is not accessible externally.

Using wrong port number or missing port.

The output combines "http://" with the instance's public IP and port 80.
