At Tembo, we want to empower developers to build fast. That’s why we built the Terraform Provider for Tembo Cloud, allowing developers to manage Postgres resources using Infrastructure-as-Code (IaC). In this blog, we'll explore the Terraform Provider for Tembo and how it can help you streamline database management while keeping teams agile, accountable and enforcing organizational policies.
Simpler, faster, safer, and easier? That’s Tembo - but let’s back up and start at the beginning.
What is Tembo Cloud?
Tembo Cloud is a developer-first, fully-extensible, fully-managed, secure, and scalable Postgres service. It not only simplifies Postgres management but also provides specialized Postgres deployments through Tembo Stacks, catering to various use cases.
Database as Code using Terraform
Databases as code provides a safe, consistent, and repeatable way of managing databases and is a game-changer for developers. This approach allows you to version-control any changes, ensuring auditability, and facilitates efficient workflows such as Pull Request flows and GitOps.
Terraform is the most popular Infrastructure as Code tool today. It provides a way to define the desired state of your infrastructure using Hashicorp Configuration Language(HCL). Terraform handles all the complexity of making sure that when changes are applied, the actual state matches the desired state. Therefore, it is an efficient way of managing databases as code.
Using Terraform Provider for Tembo
With the Terraform Provider for Tembo, you can manage Postgres databases on Tembo Cloud with all the benefits mentioned in the previous section. You can find the Terraform Provider for Tembo on the Terraform Registry along with the documentation, and the Github repo is here. A new Postgres instance can be provisioned on Tembo Cloud in about 1 minute and destroying an instance takes just 10 seconds.
Example Terraform file
You can create a new Tembo instance on Tembo Cloud using the tembo_instance resource available with the provider. Below is an example configuration.
Note: Tembo Terraform Provider needs an access_token to authenticate with the API. Generate a long-lived API token by following steps here.
terraform {
required_providers {
tembo = {
source = "tembo-io/tembo"
version = ">= 0.1.0"
}
}
}
provider "tembo" {
access_token = var.access_token
}
variable "access_token" {
type = string
}
resource "tembo_instance" "test_instance" {
instance_name = "test-instance"
org_id = "org_test" # Replace this with your Tembo organization id
cpu = "1"
stack_type = "Standard"
environment = "dev"
memory = "4Gi"
storage = "10Gi"
replicas = 1
extensions = [{
name = "plperl"
description = "PL/Perl procedural language"
locations = [{
database = "app"
schema = "public"
version = "1.0"
enabled = false
},
{
database = "postgres"
schema = "public"
version = "1.0"
enabled = true
}]
}]
}
output "instance" {
value = tembo_instance.test_instance
}
Applying the above Terraform will provision a Postgres Instance on Tembo Cloud. For a demo explaining the steps watch the video below.

The demo in the video explains how to use the Terraform Provider for Tembo. The Terraform code used in the video can be found here.
What’s next for the Provider
We are actively working on an Import feature that will allow you to import existing Tembo instances to Terraform to easily start managing existing instances with Terraform. Stay updated by starring our GitHub repository and monitoring changes on the Terraform Registry. Most importantly, please try it out, and file any issues and feature requests in our repository. You can also access the documentation for the Tembo provider here.
