Terraform Provider

• Website: https://www.terraform.io

Requirements

• Terraform 0.10.x
• Go 1.11 (to build the provider plugin)

Building The Provider

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

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

Enter the provider directory and build the provider

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

Note: For contributions created from forks, the repository should still be cloned under the $GOPATH/src/github.com/terraform-providers/terraform-provider-datadog directory to allow the provided make commands to properly run, build, and test this project.

Using the provider

If you're building the provider, follow the instructions to install it as a plugin. After placing it into your plugins directory, run terraform init to initialize it.

Further usage documentation is available on the Terraform website.

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.

To compile the provider, run make build. This will build the provider and put the provider binary in the $GOPATH/bin directory.

$ make build
...
$ $GOPATH/bin/terraform-provider-datadog
...

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

$ make test

Note that the above command runs acceptance tests by replaying pre-recorded API responses (cassettes) stored in datadog/cassettes/. When tests are modified, the cassettes need to be re-recorded.

In order to make tests cassette friendly, it's necessary to ensure that resources always get manipulated in a predictable order. When creating a testing Terraform config that defines multiple resources at the same time, you need to set inter-resource dependencies (using depends_on) in such a way that there is only one way for Terraform to manipulate them. For example, given resources A, B and C in the same config string, you can achieve this by making A depend on B and B depend on C. See PR #442 for an example of this.

Note: Recording cassettes creates/updates/destroys real resources. Never run this on a production Datadog organization.

In order to re-record all cassettes you need to have DD_API_KEY and DD_APP_KEY for your testing organization in your environment. With that, run make cassettes. Do note that this would regenerate all cassettes and thus take a very long time; if you only need to re-record cassettes for one or two tests, you can run make cassettes TESTARGS ="-run XXX" - this will effectively execute go test -run=XXX, which would run all testcases that contain XXX in their name.

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

Note: Acceptance tests create/update/destroy real resources. Never run this on a production Datadog organization.

$ make testacc

In order to update the underlying API Clients that are used by this provider to interact with the Datadog API, run:

API_CLIENT_VERSION=vx.y.z ZORKIAN_VERSION=vx.y.z make update-go-client

where:

• API_CLIENT_VERSION is the version or commit ref of the https://github.com/DataDog/datadog-api-client-go client.
• ZORKIAN_VERSION is the version or commit ref of the https://github.com/zorkian/go-datadog-api client.
