## Introduction

We provide a basic template for ZDB deployment with Terraform on the TFGrid.

A brief description of zdb fields can be found [here](https://github.com/threefoldtech/terraform-provider-grid/blob/development/docs/resources/deployment.md#nested-schema-for-zdbs). 

A more thorough description of zdb operation can be found in its parent [repo](https://github.com/threefoldtech/0-db).

## Example

```
terraform {
  required_providers {
    grid = {
      source = "threefoldtech/grid"
    }
  }
}

provider "grid" {
}

resource "grid_deployment" "d1" {
  node = 4 
  
  zdbs{
    name = "zdb1"
    size = 10 
    description = "zdb1 description"
    password = "zdbpasswd1"
    mode = "user"
  }
  zdbs{
    name = "zdb2"
    size = 2
    description = "zdb2 description"
    password = "zdbpasswd2"
    mode = "seq"
  }
}

output "deployment_id" {
    value = grid_deployment.d1.id
}

output "zdb1_endpoint" {
    value = format("[%s]:%d", grid_deployment.d1.zdbs[0].ips[0], grid_deployment.d1.zdbs[0].port)
}

output "zdb1_namespace" {
    value = grid_deployment.d1.zdbs[0].namespace
}
```
