In this tutorial article, we walk through the developers with a template project to deploy Chat Apps powered by LLMs, Langchain, and Chainlit using the Docker framework. The template project is production-ready with all batteries included. Further, a sample app is deployed to Google Cloud using Cloud Run for quick testing. This article is an extension of our previous article Build & Deploy LangChain Powered Chat App with Docker & Streamlit where we replace Streatlit with Chainlit framework.
