Terraform Provider Heroku

This provider is used to configure resources supported by the Heroku Platform API.

See the official documentation to use this provider in a Terraform configuration.

Requirements

• Terraform 1.x
• Go 1.19 (to build the provider plugin)

Usage

The configuration should specify version 5:

provider "heroku" {
  version = "~> 5.0"
}

See Upgrading guide for major version migration help.

👓📚 For more usage info, see Heroku Provider docs.

Development

If you wish to work on the provider, you'll first need Go installed on your machine (version 1.16+ is required). You'll also need to correctly setup a GOPATH, as well as adding $GOPATH/bin to your $PATH.

Clone the Provider

With Go language, the repository must be cloned to a specific path in $GOPATH/src that matches its module import path.

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

Build the Provider

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-heroku
...

Using the Provider

To use the dev provider with local Terraform, configure a dev override pointing to the directory where terraform-provider-heroku can be found:

cat << TRC >> ~/.terraformrc
provider_installation {
  dev_overrides {
    "heroku/heroku" = "$GOPATH/bin"
  }
  direct {}
}
TRC

Terraform Versions Prior to 0.13

Copy the freshly built plugin into Terraform's local plugins directory:

cp $GOPATH/bin/terraform-provider-heroku ~/.terraform.d/plugins/

Set the Heroku provider without a version constraint:

provider "heroku" {}

Then, initialize Terraform:

terraform init

Testing

Please see the TESTING guide for detailed instructions on running tests.

Updating or adding dependencies

This project uses Go Modules for dependency management.

Dependencies can be added or updated as follows:

$ GO111MODULE=on go get github.com/some/module@release-tag
$ GO111MODULE=on go mod tidy
$ GO111MODULE=on go mod vendor

This example will fetch a module at the release tag and record it in your project's go.mod and go.sum files. It's a good idea to tidy up afterward and then copy the dependencies into vendor/.

If a module does not have release tags, then module@master can be used instead.

Removing dependencies

Remove all usage from your codebase and run:

$ GO111MODULE=on go mod tidy
$ GO111MODULE=on go mod vendor
