This is the repository for the Terraform MongoDB Atlas Provider, which allows one to use Terraform with MongoDB's Database as a Service offering, Atlas.
Learn more about Atlas at  [https://www.mongodb.com/cloud/atlas](https://www.mongodb.com/cloud/atlas)

## Support, Bugs, Feature Requests

Support for the Terraform MongoDB Atlas Provider is provided under MongoDB Atlas support plans.   Please submit support questions within the Atlas UI.  Support questions submitted under the Issues section of this repo will be handled on a "best effort" basis.

Bugs should be filed under the Issues section of this repo.

Feature requests can be submitted at https://feedback.mongodb.com/forums/924145-atlas - just select the Terraform plugin as the category or vote for an already suggested feature.

## Requirements
- [Terraform](https://www.terraform.io/downloads.html) 0.13+
- [Go](https://golang.org/doc/install) 1.16 (to build the provider plugin)

## Using the Provider

To use a released provider in your Terraform environment, run [`terraform init`](https://www.terraform.io/docs/commands/init.html) and Terraform will automatically install the provider. To specify a particular provider version when installing released providers, see the [`Terraform documentation on provider versioning`](https://www.terraform.io/docs/configuration/providers.html#version-provider-versions).

Documentation about the provider specific configuration options can be found on the [provider's website](https://www.terraform.io/docs/providers/).

## Developing the Provider

If you wish to work on the provider, you'll first need [Go](https://golang.org/doc/install) installed on your machine (please check the [requirements](#Requirements) before proceeding).

Note: This project uses [Go Modules](https://blog.golang.org/using-go-modules) making it safe to work with it outside of your existing [GOPATH](https://golang.org/doc/code.html#GOPATH). The instructions that follow assume a directory in your home directory outside of the standard GOPATH (i.e $HOME/development/terraform-providers/).

Clone repository to: `$HOME/development/terraform-providers/`

```bash
mkdir -p $HOME/development/terraform-providers/; cd $HOME/development/terraform-providers/
git clone git@github.com:mongodb/terraform-provider-mongodbatlas
...
```

Enter the provider directory and run `make tools`. This will install the needed tools for the provider.

```bash
make tools
```

To compile the provider, run `make build`. This will build the provider and put its binary in the ./bin directory.

```bash
make build
...
# ./bin/terraform-provider-mongodbatlas
...
```

### Using development provider in Terraform 0.14+
From terraform version 0.14, we can override provider use for development purposes.

Just create a `.trfc` file to hold the configuration to override terraform local configuration

```hcl
provider_installation {

  dev_overrides {
    "mongodb/mongodbatlas" = "[PATH THAT CONTAINS CUSTOM PLUGIN]"
  }

  direct {}
}
```

and set the env var `TF_CLI_CONFIG_FILE` like this:
`export TF_CLI_CONFIG_FILE=PATH/TO/dev.trfc`

For more explained information about "plugin override" check [Development Overrides for Provider Developers](https://www.terraform.io/docs/cli/config/config-file.html#development-overrides-for-provider-developers)

### Testing the Provider

In order to test the provider, you can run `make test`. You can use [meta-arguments](https://www.terraform.io/docs/configuration/providers.html) such as `alias` and `version`. The following arguments are supported in the MongoDB Atlas `provider` block:

* `public_key` - (Optional) This is the MongoDB Atlas API public_key. It must be
  provided, but it can also be sourced from the `MONGODB_ATLAS_PUBLIC_KEY`
  environment variable.

* `private_key` - (Optional) This is the MongoDB Atlas private_key. It must be
  provided, but it can also be sourced from the `MONGODB_ATLAS_PRIVATE_KEY`
  environment variable.

~> **Notice:**  If you do not have a `public_key` and `private_key` you must create a programmatic API key to configure the provider (see [Creating Programmatic API key](#Programmatic-API-key)). If you already have one, you can continue with [Configuring environment variables](#Configuring-environment-variables)

### Running the acceptance test

#### Programmatic API key

It's necessary to generate and configure an API key for your organization for the acceptance test to succeed. To grant programmatic access to an organization or project using only the [API](https://docs.atlas.mongodb.com/api/) you need to know:

  1. The programmatic API key has two parts: a Public Key and a Private Key. To see more details on how to create a programmatic API key visit https://docs.atlas.mongodb.com/configure-api-access/#programmatic-api-keys.

  1. The programmatic API key must be granted roles sufficient for the acceptance test to succeed. The Organization Owner and Project Owner roles should be sufficient. You can see the available roles at https://docs.atlas.mongodb.com/reference/user-roles.

  1. You must [configure Atlas API Access](https://docs.atlas.mongodb.com/configure-api-access/) for your programmatic API key. You should allow API access for the IP address from which the acceptance test runs.

#### Configuring environment variables

You must also configure the following environment variables before running the test:

##### MongoDB Atlas env variables
```sh
export MONGODB_ATLAS_PROJECT_ID=<YOUR_PROJECT_ID>
export MONGODB_ATLAS_ORG_ID=<YOUR_ORG_ID>

```

In order to run the full suite of Acceptance tests, run ``make testacc``.

~> **Notice:** Acceptance tests create real resources, and often cost money to run. Please note in any PRs made if you are unable to pay to run acceptance tests for your contribution. We will accept "best effort" implementations of acceptance tests in this case and run them for you on our side. This may delay the contribution but we do not want your contribution blocked by funding.

```
$ make testacc
```
### Running the integration tests

The integration tests helps the validation for resources interacting with third party providers (aws, azure or gcp) using terratest [environment setup details](integrationtesting/README.md)

```
  cd integrationtesting
  go test -tags=integration
```

## Thanks

We'd like to thank [Akshay Karle](https://github.com/akshaykarle) for writing the first version of a Terraform Provider for MongoDB Atlas and paving the way for the creation of this one.
