Developer Requirements

  • Terraform (Core) - version 1.x (0.12.x and above are compatible however 1.x is recommended)
  • Go version 1.18.x (to build the provider plugin)

Contributor Guides

A Collection of guides geared towards contributors can be found in the /contributing directory of this repository.

On Windows

If you're on Windows you'll also need:

For GNU32 Make, make sure its bin path is added to PATH environment variable.*

For Git Bash for Windows, at the step of "Adjusting your PATH environment", please choose "Use Git and optional Unix tools from Windows Command Prompt".*

Or install via Chocolatey (Git Bash for Windows must be installed per steps above)

choco install make golang terraform -y
refreshenv

You must run Developing the Provider commands in bash because sh scrips are invoked as part of these.

Developing the Provider

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

First clone the repository to: $GOPATH/src/github.com/hashicorp/terraform-provider-azurerm

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

Once inside the provider directory, you can run make tools to install the dependent tooling required to compile the provider.

At this point you can compile the provider by running make build, which will build the provider and put the provider binary in the $GOPATH/bin directory.

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

You can also cross-compile if necessary:

GOOS=windows GOARCH=amd64 make build

In order to run the Unit Tests for the provider, you can run:

$ make test

The majority of tests in the provider are Acceptance Tests - which provisions real resources in Azure. It's possible to run the entire acceptance test suite by running make testacc - however it's likely you'll want to run a subset, which you can do using a prefix, by running:

make acctests SERVICE='<service>' TESTARGS='-run=<nameOfTheTest>' TESTTIMEOUT='60m'
  • <service> is the name of the folder which contains the file with the test(s) you want to run. The available folders are found in azurerm/internal/services/. So examples are mssql, compute or mariadb
  • <nameOfTheTest> should be self-explanatory as it is the name of the test you want to run. An example could be TestAccMsSqlServerExtendedAuditingPolicy_basic. Since -run can be used with regular expressions you can use it to specify multiple tests like in TestAccMsSqlServerExtendedAuditingPolicy_ to run all tests that match that expression

The following Environment Variables must be set in your shell prior to running acceptance tests:

  • ARM_CLIENT_ID
  • ARM_CLIENT_SECRET
  • ARM_SUBSCRIPTION_ID
  • ARM_TENANT_ID
  • ARM_ENVIRONMENT
  • ARM_METADATA_HOST
  • ARM_TEST_LOCATION
  • ARM_TEST_LOCATION_ALT
  • ARM_TEST_LOCATION_ALT2

Note: Acceptance tests create real resources in Azure which often cost money to run.

Developer: Using the locally compiled Azure Provider binary

After successfully compiling the Azure Provider, you must instruct Terraform to use your locally compiled provider binary instead of the official binary from the Terraform Registry.

For example, add the following to ~/.terraformrc for a provider binary located in /home/developer/go/bin:

provider_installation {

  # Use /home/developer/go/bin as an overridden package directory
  # for the hashicorp/azurerm provider. This disables the version and checksum
  # verifications for this provider and forces Terraform to look for the
  # azurerm provider plugin in the given directory.
  dev_overrides {
    "hashicorp/azurerm" = "/home/developer/go/bin"
  }

  # 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 {}
}

Developer: Generating Resource ID Formatters, Parsers and Validators

You can generate a Resource ID Formatter, Parser and Validator by adding the following line to a resourceids.go within each Service Package (for example ./internal/services/someservice/resourceids.go):

//go:generate go run ../../tools/generator-resource-id/main.go -path=./ -name=Server -id=/subscriptions/12345678-1234-9876-4563-123456789012/resourceGroups/resGroup1/providers/Microsoft.AnalysisServices/servers/Server1

Where name is the name of the Resource ID Type - and id is an example Resource ID with placeholder data.

When make generate is run, this will then generate the following for this Resource ID:

  • Resource ID Struct, containing the fields and a Formatter to convert this into a string - and the associated Unit Tests.
  • Resource ID Parser (./parse/{name}.go) - to be able to parse a Resource ID into said struct - and the associated Unit Tests.
  • Resource ID Validator (./validate/{name}_id.go) - to validate the Resource ID is what's expected (and not for a different resource) - and the associated Unit Tests.

Developer: Scaffolding the Website Documentation

You can scaffold the documentation for a Data Source by running:

$ make scaffold-website BRAND_NAME="Resource Group" RESOURCE_NAME="azurerm_resource_group" RESOURCE_TYPE="data"

You can scaffold the documentation for a Resource by running:

$ make scaffold-website BRAND_NAME="Resource Group" RESOURCE_NAME="azurerm_resource_group" RESOURCE_TYPE="resource" RESOURCE_ID="/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/group1"
