Tabular: Managing Access to Apache Iceberg Roles

In this tutorial, you'll learn how to configure Grant Kits to automate access requests to a Tabular Role. Tabular is the cloud-hosted service for Apache Iceberg. This use case models Role-Based Access Control (RBAC) within the Tabular ecosystem.

We will be using the Tabular Starter Kit as a base and replace configuration stubs for our use case.

Before you start

1. Make sure you have:

   • An Abbey account

   • An Abbey API Token

   • A Tabular account.

2. Make sure you setup:

   1. A Tabular Starter Kit by following Get a Starter Kit

   2. A Connection to a repo by following Connect a Repo

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

main.tf

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

Configure Reviewers

Workflow defines who should approve an access request.

Let's update the reviewers block by adding yourself as the reviewer by switching [e-mail] with the email address you use to sign into Abbey.

main.tf

 resource "abbey_grant_kit" "..." {
   ...
   workflow = {
     steps = [
       {
         reviewers = {
-          one_of = ["[e-mail]"] # CHANGEME
+          one_of = ["[e-mail]"]

Step 2: Configure Tabular Admin

main.tf

locals {
  ...
-  admin_email = "" # CHANGEME
+  admin_email = "[e-mail]"
}

Tabular Roles require both admin_members and members to exist, otherwise the terraform apply will fail.

Make sure to have an admin and a member for this role assignment.

Keep in mind an admin and a member cannot be the same person.

Step 3: Deploy Your Starter Kit

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

• TABULAR_CREDENTIAL

You can find this information in your Tabular account.

What should it look like?

To deploy your Starter Kit, follow instructions from Deploy Your Grant Kit.

Step 4: Automate Access Management

🎉 Congratulations! Abbey is now managing permissions to your Resource for you. 🎉

You can now start requesting and approving access by following the Request Access and Approve or Deny Access Requests guides.

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.
