This article provides a general overview of using Terraform to achieve the goal. If you prefer using a graphical interface, you can refer to the following article:
To build a chatbot, you will need to use ECS Resources with GPU and AnalyticDB for PostgreSQL with vector database capabilities. In this article, we will use terraform scripts to launch required resources, so please ensure to install a terraform environment before you start.
The 'ap-southeast-1' in the script stands for Singapore region on Alibaba Cloud. You can refer to the following blog to get all region codes of Alibaba Cloud.

#Export AK and SK
export ALIBABA_CLOUD_ACCESS_KEY_ID="Your AK ID";
export ALIBABA_CLOUD_ACCESS_KEY_SECRET="Your AK SECRET"Create a Python file and develop startup scripts to run the ChatBot application.
shell:
vim /root/chatbot.pyCopy all of the following scripts and edit line #187 to line #189, replace values accordingly with your environment. The instance ID of AnalyticDB for PostgreSQL, the private IP of ECS, and the public IP of ECS are needed.
In this article, we will load Large Language Model (LLM) ChatGLM-6B to the ChatBot. ChatGLM-6B was developed by the Tsinghua University Deep Learning Research Group. It is a 6.2 billion-parameter, open-source, multilingual version of the Generic Language Model (GLM) framework that supports both Chinese and English. You can edit the script around line #231 to use other Large Language Models, such as Dolly, GPT, and etc.
