Ollama Proxy Server

Ollama Proxy Server is a lightweight reverse proxy server designed for load balancing and rate limiting. It is licensed under the Apache 2.0 license and can be installed using pip. This README covers setting up, installing, and using the Ollama Proxy Server.

Prerequisites

Make sure you have Python (>=3.8) and Apache installed on your system before proceeding.

Installation

Clone or download the ollama_proxy_server repository from GitHub: https://github.com/ParisNeo/ollama_proxy_server
Navigate to the cloned directory in the terminal and run pip install -e .

Installation using Dockerfile

Clone this repository as described above.
Build your Container-Image with the Dockerfile provided by this repository

Podman

cd ollama_proxy_server
podman build -t ollama_proxy_server:latest .

Docker

cd ollama_proxy_server
docker build -t ollama_proxy_server:latest .

Configuration

Servers configuration (config.ini)

Create a file named config.ini in the same directory as your script, containing server configurations:

[DefaultServer]
url = http://localhost:11434
queue_size = 5

[SecondaryServer]
url = http://localhost:3002
queue_size = 3

# Add as many servers as needed, in the same format as [DefaultServer] and [SecondaryServer].

Replace http://localhost:11434/ with the URL and port of the first server. The queue_size value indicates the maximum number of requests that can be queued at a given time for this server.

Authorized users (authorized_users.txt)

Create a file named authorized_users.txt in the same directory as your script, containing a list of user:key pairs, separated by commas and each on a new line:

user1:key1
user2:key2

Replace user1, key1, user2, and key2 with the desired username and API key for each user. You can also use the ollama_proxy_add_user utility to add user and generate a key automatically:

ollama_proxy_add_user --users_list [path to the authorized `authorized_users.txt` file]

Usage

Starting the server

Start the Ollama Proxy Server by running the following command in your terminal:

python3 ollama_proxy_server/main.py --config [configuration file path] --users_list [users list file path] --port [port number to access the proxy]

The server will listen on port 808x, with x being the number of available ports starting from 0 (e.g., 8080, 8081, etc.). The first available port will be automatically selected if no other instance is running.

Client requests

To send a request to the server, use the following command:

curl -X <METHOD> -H "Authorization: Bearer <USER_KEY>" http://localhost:<PORT>/<PATH> [--data <POST_DATA>]

Replace <METHOD> with the HTTP method (GET or POST), <USER_KEY> with a valid user:key pair from your authorized_users.txt, <PORT> with the port number of your running Ollama Proxy Server, and <PATH> with the target endpoint URL (e.g., "/api/generate"). If you are making a POST request, include the --data <POST_DATA> option to send data in the body.

For example:

curl -X POST -H "Authorization: Bearer user1:key1" http://localhost:8080/api/generate --data '{'model':'mixtral:latest,'prompt': "Once apon a time,","stream":false,"temperature": 0.3,"max_tokens": 1024}'

Starting the server using the created Container-Image

To start the proxy in background with the above created image, you can use either

docker: docker run -d --name ollama-proxy-server -p 8080:8080 ollama_proxy_server:latest
podman: podman run -d --name ollama-proxy-server -p 8080:8080 ollama_proxy_server:latest
