This project is an implementation of the Terraform/OpenTofu Provider Network Mirror Protocol which provides online caching of Providers and Modules. Instead of running terraform providers mirror, you can connect to the proxy server which will serve the correct responses back to the terraform/tofu client.
The src folder contains code that converts JSON data from the online registry into the expected Mirror server JSON responses. Provider file caching is handled by a separate NGINX instance.
For configuring Provider installation using the proxy mirror, follow the instructions to configure your code:
provider_installation {
network_mirror {
url = "https://mirror.example.com/v1/providers/"
}
}The mirror also handles requests for module information, but does not cache the upstream data files due to how the protocol works.
module "example" {
source = "mirror.example.com/path/to/module"
...
}
