Terraform Cloudflare provider

Terraform Provider

• Website: https://www.terraform.io

Requirements

• Terraform 0.12.x
• Go 1.11 (to build the provider plugin)

Building The Provider

Clone repository to: $GOPATH/src/github.com/terraform-providers/terraform-provider-cloudflare

$ mkdir -p $GOPATH/src/github.com/terraform-providers; cd $GOPATH/src/github.com/terraform-providers
$ git clone https://github.com/terraform-providers/terraform-provider-cloudflare.git

When it comes to building you have two options:

make build and install it globally

If you don't mind installing the development version of the provider globally, you can use make build in the provider directory which will build and link the binary into your $GOPATH/bin directory.

$ cd $GOPATH/src/github.com/terraform-providers/terraform-provider-cloudflare
$ make build

go build and install it local to your changes

If you would rather install the provider locally and not impact the stable version you already have installed, you can use the ~/.terraformrc file to tell Terraform where your provider is. You do this by building the provider using Go.

$ cd $GOPATH/src/github.com/terraform-providers/terraform-provider-cloudflare
$ go build -o terraform-provider-cloudflare

And then update your ~/.terraformrc file to point at the location you've built it.

providers {
  cloudflare = "${GOPATH}/src/github.com/terraform-providers/terraform-provider-cloudflare/terraform-provider-cloudflare"
}

A caveat with this approach is that you will need to run terraform init whenever the provider is rebuilt. You'll also need to remember to comment it/remove it when it's not in use to avoid tripping yourself up.

Developing the Provider

If you wish to work on the provider, you'll first need Go installed on your machine (version 1.11+ 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

Managing dependencies

Terraform providers use Go modules to manage the dependencies. To add or update a dependency, you would run the following (v1.2.3 of foo is a new package we want to add):

# Depending on your environment, you may need to `export GO111MODULE=on`
# before using these commands.

$ go get foo@v1.2.3
$ go mod tidy
$ go mod vendor

Stepping through the above commands:

• go get foo@v1.2.3 fetches version v1.2.3 from the source (if needed) and adds it to the go.mod file for use.
• go mod tidy cleans up any dangling dependencies or references that aren't defined in your module file.
• go mod vendor manages the vendor directory of the project. This is done to maintain backwards compatibility with older versions of Go that don't support Go modules.

(The example above will also work if you'd like to upgrade to v1.2.3)

If you wish to remove a dependency, you can remove the reference from go.mod and use the same commands above but omit the initial go get.
