The terraform init command is one of the first and most important commands to run when working with Terraform. Its main function is to initialize a working directory containing Terraform configuration files. Here's a detailed explanation of what it does:
**What exactly does terraform init do?
Initializes the working directory: Prepares the environment so you can start using Terraform in that directory.
Downloads providers: Terraform downloads the providers (like AWS, Azure, Google Cloud, etc.) specified in the .tf files from the Terraform Registry.
Installs modules (if used): If your configuration uses remote modules (for example, from GitHub or the Registry), terraform init downloads them.
Configures the backend (if specified): If you're using a remote backend (like S3, Azure Blob, etc.) to store the state file (terraform.tfstate), this command initializes it and verifies connectivity.
Checks plugins and versions: Ensures that all required versions are compatible and available.
