ClearML Server provides a self-hosted backend for ClearML, an MLOps platform for streamlining AI workloads. It targets ML engineers and researchers needing to manage experiments, data, pipelines, and serving, offering a centralized solution for collaboration and workflow automation.

How It Works

The ClearML Server comprises a web application for UI-based experiment management, a RESTful API for logging and querying experiment data, and a file server for storing artifacts like images and models. It supports single-domain or sub-domain configurations, allowing flexible deployment via Docker, cloud AMIs, or Kubernetes. The system leverages MongoDB and Elasticsearch for data storage.

Quick Start & Requirements

• Install/Run: Deploy via Docker, AWS EC2 AMI, GCP Custom Image, or Kubernetes.
• Prerequisites: Ports 8080, 8081, and 8008 must be available. Python 3.9 is specified for the client.
• Configuration: Use clearml-init or manually edit ~/clearml.conf to point the client to the server's api_server, web_server, and files_server.
• Docs: ClearML Client

Licensing & Compatibility

• License: Server Side Public License v1.0 (SSPL).
• Compatibility: SSPL may have restrictions on offering ClearML Server as a managed service. Commercial use requires careful review of SSPL terms.

Limitations & Caveats

The ClearML Server relies on MongoDB and Elasticsearch, whose own licensing changes (SSPL, Elastic License) may impact downstream compatibility and commercial use. ClearML-Agent Services configuration is not supported on Windows installations.
