Terraform module Dagster on Azure

This is a module for Terraform that deploys Dagster in Azure.

Setup

The dagster terraform module will create the following services:

Azure Resource Group
Azure Storage Account
Azure File Share containing dagster configuration files
Azure PostgreSQL server/database
An Azure App Service:
- running the Dagit UI and Dagster Daemon containers

Average cost of the minimal setup with Azure database: ~50$/month

Intend

The Dagster setup provided with this module is intended to be used as an orchestration tool. The setup will allow you to manage your data pipelines, runs, schedules etc...

Usage

module "dagster" {
    source = "datarootsio/aci-dagster/azure"

    resource_prefix = "my-awesome-company"
    resource_suffix = "env"
    db_password = "super-secret-pass"
}

Adding new pipelines to Dagster

To add new pipelines to Dagster:

Add the new pipeline to the 'workspace.yaml' configuration file.

load_from:
  - python_file:
      relative_path: new_pipeline.py
      working_directory: /path/to/mounted/volume

Update the created Azure Fileshare by adding the new pipeline and the updated 'workspace.yaml' file. This way Dagit and the Dagster Daemon have access to the new pipeline, which will show up in the Dagit UI.

Security

This module supports HTTPS however RBAC is not supported (yet?) by Dagster. Therefore, this module results in Dagit being publicly available. It is important to note that the user should implement and manage authentication themselves, for example by implementing SSO.
