Contributing

This document is intended to be an introduction to contributing to the terraform-provider-azuredevops project.

If you are looking for background information on the project or related technologies (Terraform, Go and Azure DevOps), consider checking out some of these resources first:

If you are familiar with the technologies used for this project but are looking for general guidance on Terraform provider development, consider checking out some of these resources first:

If you are still reading, then you are in the right place!

If, after reading through the content here, you are seeking more detailed information, you may want to checkout this awesome getting started guide that was written for the terraform-provider-azurerm project. While it targets a different provider there are some great findings that you can read about

Install the dependencies

The recommended development environment is Linux or Mac. If you're on Windows you should install WSL so that your environment more closely mirrors a Linux environment.

You will need the following dependencies installed in order to get started:

Building the provider locally

Note This project uses Go Modules making it safe to work with it outside of your existing GOPATH. The instructions that follow assume a directory in your home directory outside of the standard GOPATH.

Note These steps assume you are running with bash. If you are using Windows, run all commands using WSL. They are not tested using GitBash.

Setup your workspace

$ DEV_ROOT="$HOME/workspace"
$ mkdir -p "$DEV_ROOT"
$ cd "$DEV_ROOT"

Get the code

$ git clone https://github.com/microsoft/terraform-provider-azuredevops.git
$ cd terraform-provider-azuredevops/

Build & test the provider

Running the next command will orchestrate a few things for you:

  • Verify that all required Go packages are installed. This may take a few minutes the first time you run the script as the packages will be cached locally. Subsequent runs will be much faster
  • Run all unit tests
  • Compile the provider codebase
$ ./scripts/build.sh
...
[INFO] Executing unit tests
...
[INFO] Build finished successfully

After this script runs you should see a ./bin/ directory with the compiled terraform provider.

$ ls -lah ./bin/
...
-rwxrwxrwx 1 ... terraform-provider-azuredevops_v0.0.1

Install the provider

Terraform provider plugins are not intended to be run directly. You can see this for yourself:

$ ./bin/terraform-provider-azuredevops_v0.0.1

This binary is a plugin. These are not meant to be executed directly.
Please execute the program that consumes these plugins, which will
load any plugins automatically

In order to use the provider locally it must be installed into a location discoverable by Terraform. The local-install.sh script does this for you.

$ ./scripts/local-install.sh
[INFO] Installing provider to /home/$USER/.terraform.d/plugins/

To learn more about the plugin discovery process, refer to the official Terraform provider discovery documentation.

Running the provider locally

Note These steps assume you have built the provider locally using the previous steps. The samples in the ./examples/ folder use syntax specific to Terraform 12 + and are not compatible with older versions of Terraform.

Configuring the provider

You can then use the provider just like you normally would. You can try it out by using the project examples:

$ cd examples/

$ export AZDO_ORG_SERVICE_URL="..."
$ export AZDO_PERSONAL_ACCESS_TOKEN="..."

# Note: this one is not specifically required by the provider,
# but it is required by the example in this folder...
$ export AZDO_GITHUB_SERVICE_CONNECTION_PAT="..."

$ terraform init
...
Terraform has been successfully initialized!
...

After the provider has been correctly initialized, it can be used like any other provider. You can try for yourself by running any of the terraform plan|apply|destroy|... commands.

Running the provider tests

Unit Tests

The unit tests are executed whenever ./scripts/build.sh is run. This can be run locally, but will also be run on every automated build and will be a gate for any PR against this repository. If you made it this far, you've already ran these!

The tests can also be run in isolation by running the following:

$ ./scripts/unittest.sh

Acceptance Tests (Integration Tests)

The integration tests for terraform providers are typically implemented as Acceptance Tests.

Note Running acceptance tests provisions and deletes actual resources in AzDO. This can cost money and can be dangerous if you are not running them in isolation!

Acceptance tests can be invoked by running the following:

$ ./scripts/acctest.sh

Writing your own tests

We have a great document that covers this topic in more depth.
