What is Terraform Modules?
In Terraform, a module is a container for a set of related resources that are used together to perform a specific task. Modules allow users to organize and reuse their infrastructure code, making it easier to manage complex infrastructure deployments.
Modules are defined using the ‘ module ‘ block in Terraform configuration. A module block takes the following arguments:
- source: The source location of the module. This can be a local path or a URL.
- name: The name of the module. This is used to reference the module in other parts of the configuration.
- version: The version of the module to use. This is optional and can be used to specify a specific version of the module.
Inside a module block, users can define the resources that make up the module, as well as any input and output variables that the module exposes. Input variables allow users to pass values into the module when it is called, and output variables allow the module to return values to the calling configuration. Modules can be nested, allowing users to create complex infrastructure architectures using a hierarchical structure. Modules can also be published and shared on the Terraform Registry, enabling users to reuse and extend the infrastructure code of others.
What is Terraform?
Terraform is a popular infrastructure-as-code tool that allows you to automate the provisioning and management of infrastructure resources. It uses configuration files written in the HashiCorp Configuration Language (HCL) to define the desired state of your infrastructure, and it uses various commands to apply those configurations and manage your infrastructure resources.
