Terraform Provider Boundary

Available in the Terraform Registry.

Requirements

• Terraform >= 0.13.x
• Go >= 1.21

Building The Provider

1. Clone the repository
2. Enter the repository directory
3. Build the provider using make dev. This will place the provider onto your system in a Terraform 0.13-compliant manner.

You'll need to ensure that your Terraform file contains the information necessary to find the plugin when running terraform init. make dev will use a version number of 0.0.1, so the following block will work:

terraform {
  required_providers {
    boundary = {
      source = "localhost/providers/boundary"
      version = "0.0.1"
    }
  }
}

Adding Dependencies

This provider uses Go modules. Please see the Go documentation for the most up to date information about using Go modules.

To add a new dependency github.com/author/dependency to your Terraform provider:

go get github.com/author/dependency
go mod tidy

Then commit the changes to go.mod and go.sum.

Developing the Provider

If you wish to work on the provider, you'll first need Go installed on your machine (see Requirements above).

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

In order to run the full suite of Acceptance tests, a postgres docker container must be started first:

$ go mod download # ensure boundary is installed, files are used by the docker image
$ make test-database-up

Once the test database is ready the tests can be run using make testacc.

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

$ make testacc

For more details on the docker image and troubleshooting see the boundary testing doc.

Debugging the provider

If you're using vscode, this provider has delve debugging baked into the .vscode directory. To debug you can find instructions here.

Generating Docs

This provider uses the terraform-plugin-docs tool to generate documentation. Each resource and data source requires a set of examples examples then you execute a binary to generate the docs which are placed in ./docs. Optionally, you can specify your own templates for a resource or data source if you want to add custom information (example: data "boundary_scope")

New Resources & Data Sources (documentation templates)

If you're adding a new resource or a data source, you must include a documentation template for your new R/DS in ./templates directory. This provider uses the terraform-plugin-docs tool to generate documentation. For full details see the link.

Documentation Examples for Resources & Data Sources

Examples are required for all resources and data sources. This provider uses the terraform-plugin-docs tool to generate documentation. To add examples, add a new file to the ./examples directory or update the existing files. Next make sure the corresponding template in ./templates directory references this example.

Generating

From the root of the repo run:

go run github.com/hashicorp/terraform-plugin-docs/cmd/tfplugindocs

Using the provider

Please see our detailed docs for individual resource usage. Below is a complex example using the Boundary provider to configure all resource types available:

provider "boundary" {
  addr                   = "http://127.0.0.1:9200"
  auth_method_id         = "ampw_1234567890"      # changeme
  auth_method_login_name = "myuser"               # changeme
  auth_method_password   = "passpass"             # changeme
}

variable "users" {
  type    = set(string)
