Infrahub Orchestrator

The Infrahub Orchestrator leverages Dagster to orchestrate synchronization and diff operations between data sources such as Netbox and Nautobot, utilizing the Infrahub Sync framework. It defines a structured approach to managing and executing data synchronization tasks, ensuring data consistency across different platforms.

This structure organizes the orchestrator's components, including Docker configurations, Dagster setups, and the orchestrator's core logic within the infrahub_orchestrator directory.

Jobs and Operations

The orchestrator defines three main Dagster jobs to facilitate data synchronization, diff checking, and the dynamic generation of Python adapters and sync models based on configuration file or instance name.

1. diff_job

Compares data between sources to identify differences. Utilizes specific resources for configuration and execution settings.

2. generate_job

Builds the Python adapter and sync models for a given sync instance. This job automates the setup process for data synchronization by preparing the necessary code structure and dependencies.

3. sync_job

Synchronizes data between sources with an optional diff-checking feature. It can be configured at runtime to enable or disable diff analysis, providing flexibility in data management tasks.

Configuration

Sync Job Configuration

ops:
  sync_op:
    config:
      diff: True

resources:
  sync_instance_resource:
    config:
      config_file: /tmp/from-netbox/config.yml

potenda_resource:
  config:
    branch: main
    show_progress: True

Diff Job Configuration

resources:
  sync_instance_resource:
    config:
      config_file: /tmp/from-nautobot-v1/config.yml

potenda_resource:
  config:
    branch: main
    show_progress: True

Scheduling

The sync_job is scheduled to run every hour, between 09:00 AM and 04:59 PM GMT+1, from Sunday through Friday, using the following cron expression: 0 9-16 * * 0-5.

Getting Started

To run the orchestrator, ensure Docker and Docker Compose are installed on your system. Then, execute the following commands:

docker compose build
docker compose up -d

This will start the Dagster instance and the orchestrator, ready to execute the defined jobs based on the provided schedules or manual triggers through the Dagster UI.
