OPEA | openEuler

Current OPEA docker images are built on the openEuler⁠. This repository is free to use and exempted from per-user rate limits.

OPEA is an open platform project that lets you create open, multi-provider, robust, and composable GenAI solutions that harness the best innovation across the ecosystem.

The OPEA platform includes:

• Detailed framework of composable building blocks for state-of-the-art generative AI systems including LLMs, data stores, and prompt engines

• Architectural blueprints of retrieval-augmented generative AI component stack structure and end-to-end workflows

• A four-step assessment for grading generative AI systems around performance, features, trustworthiness, and enterprise-grade readiness

Supported tags and respective Dockerfile links

The tag of each CodeTrans docker image is consist of the version of CodeTrans and the version of basic image. The details are as follows

Tags	Currently	Architectures
1.0-oe2403lts	CodeTrans 1.0 on openEuler 24.03-LTS	amd64
1.2-oe2403lts	CodeTrans 1.2 on openEuler 24.03-LTS	amd64

Usage

The CodeTrans service can be effortlessly deployed on either Intel Gaudi2 or Intel Xeon Scalable Processor.

Currently we support two ways of deploying CodeTrans services with docker compose:

1. Start services using the docker image on docker hub:

   docker pull openeuler/codetrans:latest
   

2. Start services using the docker images built from source.

Required Models

By default, the LLM model is set to a default value as listed below:

Service	Model
LLM	mistralai/Mistral-7B-Instruct-v0.3

Quick Start: 1.Setup Environment Variable

To set up environment variables for deploying CodeTrans services, follow these steps:

1. Set the required environment variables:

   # Example: host_ip="192.168.1.1"
   export host_ip="External_Public_IP"
   # Example: no_proxy="localhost, 127.0.0.1, 192.168.1.1"
   export no_proxy="Your_No_Proxy"
   export HUGGINGFACEHUB_API_TOKEN="Your_Huggingface_API_Token"
   

2. If you are in a proxy environment, also set the proxy-related environment variables:

   export http_proxy="Your_HTTP_Proxy"
   export https_proxy="Your_HTTPs_Proxy"
   

3. Set up other environment variables:

   Get set_env.sh here: set_env.sh

   source set_env.sh
   

Quick Start: 2.Run Docker Compose

Get compose.yml here: compose.yml

docker compose -f compose.yml up -d

It will automatically download the docker image on docker hub:

docker pull openeuler/codetrans:latest
docker pull openeuler/codetrans-ui:latest

QuickStart: 3.Consume the CodeGen Service

1. Use cURL command on terminal

   curl http://${host_ip}:7777/v1/codetrans \
       -H "Content-Type: application/json" \
       -d '{"language_from": "Golang","language_to": "Python","source_code": "package main\n\nimport \"fmt\"\nfunc main() {\n    fmt.Println(\"Hello, World!\");\n}"}'
   

2. Access via frontend

   To access the frontend, open the following URL in your browser: http://{host_ip}:5173.

   By default, the UI runs on port 5173 internally.
