A provider is a Terraform plugin that allows users to manage an external API. Provider plugins like the AWS provider or the cloud-init provider act as a translation layer that allows Terraform to communicate with many different cloud providers, databases, and services.
Also question is, can I use multiple providers in Terraform?
Configuring Multiple AWS providers
We can’t write two or more providers with the same name i.e. two AWS providers. If there’s any such need the terraform has provided a way to do that which is to use alias argument. Note: A provider block without an alias argument is the default configuration for that provider.
- The Provider must know the address of the API to communicate with it.
- The Provider must know how to map specific keywords in the HCL code to specific API calls.
- The Provider must know how to flatten the API response JSON into a format that Terraform can output to the user.
Moreover, how do I pass a provider to Terraform module?
Provider configurations can be defined only in a root Terraform module. Providers can be passed down to descendent modules in two ways: either implicitly through inheritance, or explicitly via the providers argument within a module block.
