Variable Block
Declaring input variables that can be provided during Terraform execution for flexible configurations.Variables enable you to give arguments your infrastructure and make it more flexible. You can define variables for values that may vary across environments or deployments, such as the number of instances or the size of a storage volume. By utilizing variable blocks, you can easily customize and reuse your configuration for different scenarios without modifying the underlying code.
- Defining input variables for the Terraform configuration.
- Providing flexibility and parameterization to the configuration.
- Allowing users to provide values during Terraform runs or through variable files.
Example:
variable "instance_count" { description =
"Number of instances to create" type
= number default = 1 }
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:
