# Terraform Provider: External
The external provider 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.
## Requirements
* [Terraform](https://www.terraform.io/downloads)
* [Go](https://go.dev/doc/install) (1.22)
* [GNU Make](https://www.gnu.org/software/make/)
* [golangci-lint](https://golangci-lint.run/usage/install/#local-installation) (optional)## Documentation, questions and discussions
Official documentation on how to use this provider can be found on the
[Terraform Registry](https://registry.terraform.io/providers/hashicorp/external/latest/docs).
In case of specific questions or discussions, please use the
HashiCorp [Terraform Providers Discuss forums](https://discuss.hashicorp.com/c/terraform-providers/31),
in accordance with HashiCorp [Community Guidelines](https://www.hashicorp.com/community-guidelines).We also provide:
* [Support](.github/SUPPORT.md) page for help when using the provider
* [Contributing](.github/CONTRIBUTING.md) guidelines in case you want to help this project## Compatibility
Compatibility table between this provider, the [Terraform Plugin Protocol](https://www.terraform.io/plugin/how-terraform-works#terraform-plugin-protocol)
version it implements, and Terraform:| External Provider | Terraform Plugin Protocol | Terraform |
|:-----------------:|:-------------------------:|:---------:|
| `>= 2.0.x` | `5` | `>= 0.12` |
| `>= 1.1.x` | `4` and `5` | `>= 0.12` |
| `<= 1.x.x` | `4` | `<= 0.12` |Details can be found querying the [Registry API](https://www.terraform.io/internals/provider-registry-protocol#list-available-versions)
that return all the details about which version are currently available for a particular provider.
[Here](https://registry.terraform.io/v1/providers/hashicorp/external/versions) are the details for Time (JSON response).## Development
### Building
1. `git clone` this repository and `cd` into its directory
2. `make` will trigger the Golang buildThe provided `GNUmakefile` defines additional commands generally useful during development,
like for running tests, generating documentation, code formatting and linting.
Taking a look at it's content is recommended.### Testing
In order to test the provider, you can run
* `make test` to run provider tests
* `make testacc` to run provider acceptance testsIt's important to note that acceptance tests (`testacc`) will actually spawn
`terraform` and the provider. Read more about they work on the
[official page](https://www.terraform.io/plugin/sdkv2/testing/acceptance-tests).### Generating documentation
This provider uses [terraform-plugin-docs](https://github.com/hashicorp/terraform-plugin-docs/)
to generate documentation and store it in the `docs/` directory.
Once a release is cut, the Terraform Registry will download the documentation from `docs/`
and associate it with the release version. Read more about how this works on the
[official page](https://www.terraform.io/registry/providers/docs).Use `make generate` to ensure the documentation is regenerated with any changes.
### Using a development build
If [running tests and acceptance tests](#testing) isn't enough, it's possible to set up a local terraform configuration
to use a development builds of the provider. This can be achieved by leveraging the Terraform CLI
[configuration file development overrides](https://www.terraform.io/cli/config/config-file#development-overrides-for-provider-developers).First, use `make install` to place a fresh development build of the provider in your
[`${GOBIN}`](https://pkg.go.dev/cmd/go#hdr-Compile_and_install_packages_and_dependencies)
(defaults to `${GOPATH}/bin` or `${HOME}/go/bin` if `${GOPATH}` is not set). Repeat
this every time you make changes to the provider locally.Then, setup your environment following [these instructions](https://www.terraform.io/plugin/debugging#terraform-cli-development-overrides)
to make your local terraform use your local build.### Testing GitHub Actions
This project uses [GitHub Actions](https://docs.github.com/en/actions/automating-builds-and-tests) to realize its CI.
Sometimes it might be helpful to locally reproduce the behaviour of those actions,
and for this we use [act](https://github.com/nektos/act). Once installed, you can _simulate_ the actions executed
when opening a PR with:```shell
# List of workflows for the 'pull_request' action
$ act -l pull_request# Execute the workflows associated with the `pull_request' action
$ act pull_request
```## Releasing
The release process is automated via GitHub Actions, and it's defined in the Workflow
[release.yml](./.github/workflows/release.yml).Each release is cut by pushing a [semantically versioned](https://semver.org/) tag to the default branch.
