Terraform Provider Scaffolding

This repository is a template for a Terraform provider. It is intended as a starting point for creating Terraform providers, containing:

• A resource, and a data source (internal/provider/),
• Examples (examples/) and generated documentation (docs/),
• Miscellanious meta files.

These files contain boilerplate code that you will need to edit to create your own Terraform provider. A full guide to creating Terraform providers can be found at Writing Custom Providers.

Please see the GitHub template repository documentation for how to create a new repository from this template on GitHub.

Once you've written your provider, you'll want to publish it on the Terraform Registry so that others can use it.

Requirements

• Terraform >= 0.13.x
• Go >= 1.17

Build the Aquasec Provider

The Aquasec Terraform provider can be pulled from the Hashicorp registry as for the included examples in this repository.

As an alternative, and for development purposes, you can build the provider locally with the following instructions.

Clone the repo

Clone the repository locally and switch to the version you want to try

git clone https://github.com/aquasecurity/terraform-provider-aquasec.git

cd terraform-provider-aquasec

git checkout v0.8.20

Build and install the provider

make build install

The last command will compile the Terraform Provider and generate a terraform-provider-aquasec binary in your local directory and then will install into the folder containing the Terraform resources.

Install the provider

After a successful build, the generated binary will need to be installed into the folder containing the Terraform resources.

We'll use here the example Terraform resources provided in this repo.

Terraform configuration

In order to test the provider installed locally, the provider block will have to include the path to the current binary, as in the following example

terraform {
  required_providers {
    aquasec = {
      version = "0.8.27"
      source  = "terraform-provider-aquasec/aquasec/aquasec"
    }
  }
}

Test Aquasec Terraform Provider

Now you can carry on initialising Terraform in your folder with the resources. This step will be very shortly since Terraform won't download the provider but use instead the local binary

terraform init

Finally, make sure to replace the Aqua credentials and URL in the provider block and start trying out the different resources as provided in the example file.

provider "aquasec" {
  username = "admin"
  aqua_url = "https://aquaurl.com"
  password = "@password"
}

Documentation generation

This will allow you to locally generate updates to the documentation (found in the docs directory).

go install github.com/hashicorp/terraform-plugin-docs/cmd/tfplugindocs # check source url in tools/tools.go

Ensure GOBIN is set correctly, or that the installed tfplugindocs tool is available on your PATH.

which tfplugindocs # if not found, check in your $GOPATH/bin/tfplugindocs

Ensure you are in the root directory of the project, and run

tfplugindocs generate

The tool will analyse the source code, and automatically build a schema map, with Description fields allowing for some additional context to be provided. It will also iterate through template files in templates/, and example code for each resource can be provided at examples/resources/[full resource name]/resource.tf. Similarly, for data sources, the location is examples/data-sources/[full data source name]/data-source.tf.

The output in the docs directory is what gets published on https://registry.terraform.io. Please take care to provide quality documentation and examples of resources and data sources developed for the provider.
