What are Terraform outputs and how do I use them?

What are Terraform outputs?

Terraform outputs are values that are extracted from your Terraform state file and can be used to display information after your infrastructure is created.

How do I define outputs in my Terraform configuration?

You can define outputs in your Terraform configuration using the output block. For example:

output "instance_ip" {
  value = aws_instance.my_instance.public_ip
}

Can I use outputs in other Terraform modules?

Yes, you can use outputs from one module in another by referencing them. For example, if you have an output called instance_ip in a module, you can access it like this: module.my_module.instance_ip.

What is the purpose of using outputs?

Outputs are useful for sharing information between modules, displaying important values after deployment, and for use in automation scripts.
