# Databricks: Managing Access to Groups

In this tutorial, you'll learn how to configure [#grant-kits](https://docs.abbey.io/how-abbey-works/concepts#grant-kits "mention") to automate access requests to a [Databricks Group](https://registry.terraform.io/providers/databricks/databricks/latest/docs/resources/group) by attaching [Group Members](https://registry.terraform.io/providers/databricks/databricks/latest/docs/resources/group_member). This use case models Role-Based Access Control (RBAC) for Databricks.

We will be using the [Databricks Starter Kit](https://github.com/abbeylabs/abbey-starter-kit-databricks) as a base and replace configuration stubs for our use case.

## Before you start

1. **Make sure you have:**
   * An [Abbey account](https://app.abbey.so/sign-up)
   * An [Abbey API Token](https://docs.abbey.io/admin/managing-api-tokens#creating-new-api-tokens)
   * A Databricks account
2. **Make sure you setup:**
   1. A [Databricks Starter Kit](https://github.com/abbeylabs/abbey-starter-kit-databricks) by following [get-a-starter-kit](https://docs.abbey.io/build-a-grant-kit/get-a-starter-kit "mention")
   2. A Connection to a repo by following [connect-a-repo](https://docs.abbey.io/build-a-grant-kit/connect-a-repo "mention")

## Step 1: Configure Your Grant Kit

### Configure Output

Grant Kits rely on your GitHub account and repository name to output access changes, which we'll set through Terraform local variables. Update the `locals` block in `main.tf` with your `account_name` and `repo_name`

{% code title="main.tf" %}

```hcl
 locals {
  account_name = "" #CHANGEME
  repo_name = "" #CHANGEME
  ...
}
```

{% endcode %}

### Configure Reviewers

Workflow defines who should approve an access request. 

Let's update the `reviewers` block by adding yourself as the reviewer by switching `replace-me@example.com` with the email address you use to sign into Abbey. 

{% code title="main.tf" %}

```diff
 resource "abbey_grant_kit" "..." {
   ...
   workflow = {
     steps = [
       {
         reviewers = {
-          one_of = ["replace-me@example.com"] # CHANGEME
+          one_of = ["alice@example.com"]
```

{% endcode %}

## Step 3: Link Databricks with Abbey

Now you'll need to link [Databricks with Abbey](https://developers.abbey.io/#operation/createAppData). 

{% code title="" %}

```diff
curl -X POST \
  -H "Authorization: Bearer $ABBEY_API_TOKEN" \
  -H 'Content-Type: application/json' \
  https://api.abbey.io/v1/users/<user_id>/apps \
  -d '{"type": "databricks", "data": {"user_name": "<your Databricks user name", "tf_resource_id": "<the id of the Terraform resource for your user>"}}'
```

{% endcode %}

## Step 3: Replace Databricks-Related Stubs

You'll need to log into your Databricks account to get your database, role, user(s), table schema, and table name.

{% code title="main.tf" lineNumbers="true" %}

```diff
...

resource "databricks_group" "pii_group" {
  display_name               = "PII Group"
  allow_cluster_create       = true
  allow_instance_pool_create = true
}

- resource "databricks_user" "replace_me_user" {
+ resource "databricks_user" "alice_user" {
-  user_name    = "replace-me@example.com"
+  user_name    = "alice@example.com"
}

...
```

{% endcode %}

## Step 4: Deploy Your Starter Kit

First, add your Databricks-related secrets to your repo:

* `DATABRICKS_HOST`
* `DATABRICKS_TOKEN`

You can find this information in your Databricks account.

</details>

To deploy your Starter Kit, follow instructions from [deploying-your-grant-kit](https://docs.abbey.io/build-a-grant-kit/deploying-your-grant-kit "mention").

## Step 5: Automate Access Management

:tada: Congratulations! Abbey is now managing permissions to your Databricks Group for you. :tada:

You can now start requesting and approving access by following the [requesting-access](https://docs.abbey.io/build-a-grant-kit/requesting-access "mention") and [approving-or-denying-access-requests](https://docs.abbey.io/build-a-grant-kit/approving-or-denying-access-requests "mention") guides.

{% hint style="success" %}
Abbey strives to help you automate and secure access management without being intrusive.

To that end, this Pull Request contains native Terraform HCL code using normal open source Terraform Provider libraries. It represents the permissions change. In this case, it's just a simple creation of a new Terraform Resource.
