Harbor App Demo

https://github.com/user-attachments/assets/a5cd2ef1-3208-400a-8866-7abd85808503

In the demo, Harbor App is used to launch a default stack with Ollama and Open WebUI services. Later, SearXNG is also started, and WebUI can connect to it for the Web RAG right out of the box. After that, Harbor Boost is also started and connected to the WebUI automatically to induce more creative outputs. As a final step, Harbor config is adjusted in the App for the klmbr module in the Harbor Boost, which makes the output unparsable for the LLM (yet still undetstandable for humans).

Why?

• If you're comfortable with Docker and Linux administration - you likely don't need Harbor to manage your local LLM environment. However, while growing it - you're also likely to eventually arrive to a similar solution. I know this for a fact, since that's exactly how Harbor came to be.
• Harbor is not designed as a deployment solution, but rather as a helper for the local LLM development environment. It's a good starting point for experimenting with LLMs and related services.
• Workflow/setup centralisation - you can be sure where to find a specific config or service, logs, data and configuration files.
• Convenience factor - single CLI with a lot of services and features, accessible from anywhere on your host.
