Terraform is an open-source infrastructure as code (IaC) tool created by HashiCorp. It allows developers to define and provision data center infrastructure using a high-level configuration language known as HashiCorp Configuration Language (HCL), or optionally JSON. Terraform is widely used for managing infrastructure across various cloud providers, enabling consistent and repeatable infrastructure deployments.
When working with Terraform, you might encounter the error message: Error: Module not found. This error typically occurs during the terraform init or terraform apply commands, indicating that Terraform is unable to locate a specified module in your configuration files.
The Module not found error generally arises when Terraform cannot find a module due to incorrect module source paths, missing modules, or issues with module repositories. Modules in Terraform are containers for multiple resources that are used together, and they can be sourced from local paths, Terraform Registry, or version control systems like GitHub.
To resolve the Module not found error, follow these steps:
Ensure that the module source path is correctly specified in your Terraform configuration file. For example, if you are sourcing a module from the Terraform Registry, the source should look like:
module "example" {
source = "hashicorp/example"
}
For modules from a Git repository, ensure the URL is correct:
module "example" {
source = "git::https://github.com/user/repo.git"
}
Ensure that your network connection is stable and that you have access to the module repository. You can test connectivity by trying to access the repository URL directly in a web browser or using curl:
curl -I https://github.com/user/repo.git
Confirm that the module exists in the specified source location. If the module is hosted on a version control system, check that the repository and branch/tag are correct and accessible.
If the module path or repository has changed, update your Terraform configuration to reflect the new source. After making changes, run:
terraform init
This command reinitializes the working directory and downloads the updated modules.
