* "external" provider for gluing in external logic This provider will become a bit of glue to help people interface external programs with Terraform without writing a full Terraform provider. It will be nowhere near as capable as a first-class provider, but is intended as a light-touch way to integrate some pre-existing or custom system into Terraform. * Unit test for the "resourceProvider" utility function This small function determines the dependable name of a provider for a given resource name and optional provider alias. It's simple but it's a key part of how resource nodes get connected to provider nodes so worth specifying the intended behavior in the form of a test. * Allow a provider to export a resource with the provider's name If a provider only implements one resource of each type (managed vs. data) then it can be reasonable for the resource names to exactly match the provider name, if the provider name is descriptive enough for the purpose of the each resource to be obvious. * provider/external: data source A data source that executes a child process, expecting it to support a particular gateway protocol, and exports its result. This can be used as a straightforward way to retrieve data from sources that Terraform doesn't natively support.. * website: documentation for the "external" provider

External Provider
external is a special provider that exists to provide an interface
between Terraform and external programs.
Using this provider it is possible to write separate programs that can participate in the Terraform workflow by implementing a specific protocol.
This provider is intended to be used for simple situations where you wish to integrate Terraform with a system for which a first-class provider doesn't exist. It is not as powerful as a first-class Terraform provider, so users of this interface should carefully consider the implications described on each of the child documentation pages (available from the navigation bar) for each type of object this provider supports.
~> Warning Terraform Enterprise does not guarantee availability of any particular language runtimes or external programs beyond standard shell utilities, so it is not recommended to use this provider within configurations that are applied within Terraform Enterprise.
