# Terraform Provider for env0

[![Go Report Card](https://goreportcard.com/badge/github.com/env0/terraform-provider-env0)](https://goreportcard.com/report/github.com/env0/terraform-provider-env0)

- [Documentation](https://registry.terraform.io/providers/env0/env0/latest/docs)
- [Usage Examples](https://github.com/env0/terraform-provider-env0/tree/main/examples)

## Quick Start

```terraform
terraform {
required_providers {
env0 = {
source = "env0/env0"
}
}
}

provider "env0" {}

data "env0_project" "default_project" {
name = "My First Project"
}

resource "env0_template" "example" {
name = "example"
description = "Example template"
repository = "https://github.com/env0/templates"
path = "aws/hello-world"
}

resource "env0_configuration_variable" "in_a_template" {
name = "VARIABLE_NAME"
value = "some value"
template_id = env0_template.tested1.id
}
```

## Authentication

1. Generate an `api_key` and `api_secret` from the Organization Settings page.
See [here](https://developer.env0.com/docs/api/YXBpOjY4Njc2-env0-api#creating-an-api-key).

2. These can be provided by one of two methods:

1. Set `ENV0_API_KEY` and `ENV0_API_SECRET` environment variables, and just declaring the provider with no parameters:

```terraform
provider "env0" {}
```

2. Specify these fields as parameters to the provider:

```terraform
variable "env0_api_key" {}
variable "env0_api_secret" {}

provider "env0" {
api_key = var.env0_api_key
api_secret = var.env0_api_secret
}
```

### How to get VCS credentials for Creating a template or a VCS environment

To create an `env0_template` or a VCS `env0_environment` resources a user must provision the corresponding credentials:

1. `github_installation_id` for Github
2. `bitbucket_client_key` for Bitbucket
3. `gitlab_project_id` + `token_id` for Gitlab
4. `token_id` for Azure DevOps

To get those credentials in the provider you must first create a "master" environment via the `env0` app, then just fetch the corresponding `env0_environment` data source and use the relevant credentials:

```
data "env0_environment" "master_environment" {
id = "exampleId"
}

resource "env0_template" "example" {
name = "example AzureDevOps"
description = "Example AzureDevOps template"
repository = "https://dev.azure.com/example-org/AWS/_git/example"
path = "hello-world"
token_id = data.env0_environment.master_environment.token_id
}
```

## Development Setup

> **Supported Go Version: 1.21**

### Build

- Use the `./build.sh` script.
- The output binary is called `terraform-provider-env0`

### Run local version of the provider

- Build - `./build.sh`
- Create the plugins folder - `mkdir -p ~/.terraform.d/plugins/terraform.env0.com/local/env0/6.6.6/darwin_amd64` (for M1 processor, replace `amd64` with `arm64`)
- Copy the built binary - `cp ./terraform-provider-env0 ~/.terraform.d/plugins/terraform.env0.com/local/env0/6.6.6/darwin_amd64` (Replace `darwin` with `linux` on Linux)
- Require the local provider in your `main.tf` -

```
terraform {
required_providers {
env0 = {
version = "6.6.6"
source = "terraform.env0.com/local/env0"
}
}
}
```

### Installing pre-commit hooks

For consistent coding style, install [pre-commit](https://pre-commit.com/#install) hooks.

```
go install golang.org/x/tools/...@latest
go install honnef.co/go/tools/cmd/staticcheck@latest
pre-commit install
pre-commit install --hook-type pre-push
```

## Testing

### Integration tests

- The integration tests run against the real env0 API
- Have `ENV0_API_KEY` and `ENV0_API_SECRET` environment variables defined.
- Also set `ENV0_API_ENDPOINT` if you want to run against a non-prod environment.
- Run `go run tests/harness.go` (from the project root folder) to run all the tests.
- Use `go run tests/harness.go 003_configuration_variable` to run a specific test.

Each test perform the following steps:

- `terraform init`
- `terraform apply -auto-approve -var second_run=0`
- `terraform apply -auto-approve -var second_run=1`
- `terraform outputs -json` - and verifies expected outputs from `expected_outputs.json`
- `terraform destroy`

The harness has two modes to help while developing: If an environment variable `DESTROY_MODE` exists and it's value is `NO_DESTROY`, the harness will avoid calling `terraform destroy`, allowing the developer to inspect the resources created, through the dashboard, for example.
Afterwards, when cleanup is required, just set `DESTROY_MODE` to `DESTROY_ONLY` and _only_ `terraform destroy` will run.

#### Integration Test Prerequisites

- An env0 organization
- An API Key
- A Github.com integrated template name `Github Integrated Template` for https://github.com/env0/templates
- A Gitlab.com integrated template name `Gitlab Integrated Template` for https://gitlab.com/env0/gitlab-vcs-integration-tests

### Unit Testing

#### How to run tests

Run from root directory:

```shell
go test -v ./...
```

#### Running a single provider test

```shell
export TEST_PATTERN="TestUnitConfigurationVariableResource/Create" && go test -v ./env0
```

#### How to use mocks

1. Make sure `GOPATH` is in your `PATH`

```shell
go env GOPATH
echo $PATH
export PATH=$PATH:$(go env GOPATH) # if not
```

2. Install mockgen

```
go install go.uber.org/mock/[email protected]
```

3. Make sure to add this line in files that include the interface you'd wish to mock:

```
//go:generate mockgen -destination=_mock.go -package= .
```

4. Run from root directory:

```shell
go generate ./...
```

## Documentation

- Docs are generated using github.com/hashicorp/terraform-plugin-docs
- Run `./generate-docs.sh` to generate docs
- Must be run manually before releasing a version
- Please add an example to `examples//env0_` dir and make sure it is added to the docs.

## Release

To release a version to the [Terraform Public Registry](https://registry.terraform.io/providers/env0/env0/latest?pollNotifications=true):

1. Validate that all status checks are ✅ on `main` branch (specifically that docs generation is complete)
2. Pull from remote first - `git pull origin main`
3. Create and push a tag **locally**, in semver format - `git tag v0.0.9 && git push origin --tags`
4. New release with binaries **will be automatically generated** by the GitHub action defined in `.github/workflows/release.yml`.
5. The Registry will automatically pick up on the new version.
