Development Environment Setup

Requirements

  • Terraform 0.14+ (to run acceptance tests)
  • Go 1.17 (to build the provider plugin)

Quick Start

If you wish to work on the provider, you'll first need Go installed on your machine (version 1.17+ is required). You'll also need to correctly setup a GOPATH, as well as adding $GOPATH/bin to your $PATH.

See above for which option suits your workflow for building the provider.

In order to test the provider, you can simply run make test.

$ make test

In order to run the full suite of Acceptance tests, run make testacc.

Note: Acceptance tests create real resources, and often cost money to run.

$ make testacc

You can also install other optional (but great to have tools) using make tools. Most of these tools run in CI automatically but helps having these locally to either hook into your editor or debug CI failures.

Using the Provider

With Terraform v0.14 and later, development overrides for provider developers can be leveraged in order to use the provider built from source.

To do this, populate a Terraform CLI configuration file (~/.terraformrc for all platforms other than Windows; terraform.rc in the %APPDATA% directory when using Windows) with at least the following options:

provider_installation {
  dev_overrides {
    "cloudflare/cloudflare" = "<GOPATH>/src/github.com/cloudflare/terraform-provider-cloudflare"
  }

  # For all other providers, install them directly from their origin provider
  # registries as normal. If you omit this, Terraform will _only_ use
  # the dev_overrides block, and so no other providers will be available.
  direct {}
}

You will need to replace <GOPATH> with the full path to your GOPATH where the repository lives, no ~ shorthand.

Once you have this file in place, you can run make build-dev which will build a development version of the binary in the repository that Terraform will use instead of the version from the remote registry.

Pulling in unreleased changes from Go library (cloudflare-go)

In some scenarios, you may be wanting to make changes in cloudflare-go and have them reflected in the Terraform provider before they are released upstream. To do this, you can update the go.mod file locally (do not commit it) using go mod replace.

replace github.com/cloudflare/cloudflare-go => ../cloudflare-go

Updating the second path to wherever the local library sits on your machine.
