Output Block
Defining values that are displayed as output after executing terraform apply or terraform output commands.Outputs can include information like IP addresses, URLs, or resource identifiers that are useful for interacting with the given infrastructure. By defining output blocks, you can extract important information from your infrastructure and provide it to users or other systems for further actions or integrations.
- Exposing calculated or derived values from the Terraform configuration.
- Communicating important information to users after the Terraform run.
- Sharing outputs with other configurations or scripts.
output "instance_ip" { value = aws_instance.example.
public_ip description = "Public IP of the created instance" }
Different Types of Blocks in Terraform
Terraform is an infrastructure as a code tool that allows you to define and configure your infrastructure using your declarative code. Its syntax is very simple. Terraform uses a configuration language to describe the desired state of your infrastructure, and this language is composed of various block types. These block types play a crucial role in defining and configuring infrastructure in Terraform.
In Terraform, a block is a fundamental unit used to define and configure different aspects of your infrastructure. Blocks are written in HashiCorp Configuration Language (HCL) and allow you to declare resources, providers, variables, outputs, and other configuration elements within your Terraform code.
Each block serves a specific purpose and has its own syntax and set of properties. Here are some common block types used in Terraform:
