The content in this document is subject to change.

  • OS: Ubuntu 22.04.3 LTS

  • Web Server: Nginx 1.14.0 or later

  • Docker: 24.0.0 or later

  • Docker Compose: 2.23.0 or later

  • AWS CLI: 2.13.30 or later

  • Python: 3.10 or later

Hardware

  • Memory: 32GB RAM minimum

  • Disk Space: 20GB is required for safe installation. Recommended an additional 500 GB for database storage

Network

  • Allowed traffic through port 80/443

External Services

  • SendGrid API key

  • OpenAI or Azure OpenAI API key

GPT data privacy

It's recommended to use Azure's OpenAI service instead of OpenAI directly. The benefits of Azure’s OpenAI service include:

  1. Faster response times

  2. 99.9% uptime SLA

    We guarantee that Azure OpenAI Service will be available at least 99.9% of the time.

  3. Stronger data privacy

Data, privacy, and security for Azure OpenAI Service - Azure AI services

Your prompts (inputs) and completions (outputs), your embeddings, and your training data:

  • are NOT available to other customers.

  • are NOT available to OpenAI.

  • are NOT used to improve OpenAI models.

  • are NOT used to improve any Microsoft or 3rd party products or services.

  • are NOT used for automatically improving Azure OpenAI models for your use in your resource (The models are stateless, unless you explicitly fine-tune models with your training data).

  • Your fine-tuned Azure OpenAI models are available exclusively for your use.

The Azure OpenAI Service is fully controlled by Microsoft; Microsoft hosts the OpenAI models in Microsoft’s Azure environment and the Service does NOT interact with any services operated by OpenAI (e.g. ChatGPT, or the OpenAI API).

Installation

There are three components that must be served by this machine:

  1. The backend platform

  2. The web app

  3. The webchat library

These three components can be served directly from Nginx. As components (2) and (3) are pre-built, they only need to be served as static files from Nginx without any configuration.

💡 See Configuration for an example Nginx configuration.

You will be provided with the following files to scaffold the on-premise deployment:

  1. A Python file, called proto_scaffold.py

  2. A JSON file, called proto_credentials.json

Head to your desired installation directory, and place both of these files in this directory.

Run python proto_scaffold.py init

The command will not start Proto. It will create a folder with the relevant service configuration TOML files, authenticate your instance with our private docker container repository, and add a docker-compose.yml.

Configuration

In the newly created directory, you'll find a subdirectory named backend/config/. This contains all the configurable parameters for the backend platform. While many parameters might not require adjustments, the following are mandatory:

[app]
base_url = "https://{YOUR_URL}"
base_api_url = "https://{YOUR_URL}/api"

[cors]
allow_origins = ['https://{YOUR_URL}']

[sendgrid]
api_key = "{YOUR_SENDGRID_API_KEY}"
from_domain = "{YOUR_DESIRED_EMAIL_FROM}"
inbound_parse_key = "{YOUR_SENDGRID_INBOUND_URL_KEY_PARAM}"

[openai]
api_key = "{YOUR_OPENAI_API_KEY}"

[api]
session_middleware_secret_key = "{YOUR_RANDOM_SECRET_KEY_1}"
secret_key = "{YOUR_RANDOM_SECRET_KEY_2}"
algorithm = "HS256"
access_token_expire_minutes = 3600
frontend_url = "https://{YOUR_URL}"

...

Example Nginx configuration

The backend platform will run its services on port 8080 of the containers. Each service should be prefixed with api/. The web app and the webchat library will be served from / and /webchat, respectively.

location / {
		# Serve web app
    root /home/ubuntu/proto/frontend;
    index index.html;
    try_files $uri $uri/ /index.html;
}

location /webchat {
		# Serve webchat
    root /home/ubuntu/proto/webchat;

}

location /msgrouter_ws/ {
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection 'upgrade';
    proxy_set_header Host $host;

    proxy_pass http://msgrouter_ws:9000;
}

Managing platform state

  • Start the platform: run docker compose up -d in backend/

  • Stop the platform: run docker compose down in backend/

  • Update the platform from remote: python proto_scaffold.py update

  • Directly connect to database: psql -U postgres -d platform
