embeddingsearch/docs/Server.md

Overview

The server by default

• runs on port 5146
• Uses Swagger UI in development mode (/swagger/index.html)
• Ignores API keys when not in development mode

Installing the dependencies

Ubuntu 24.04

1. Install the .NET SDK: sudo apt update && sudo apt install dotnet-sdk-8.0 -y

Windows

Download the .NET SDK or follow these steps to use WSL:

1. Install Ubuntu in WSL (wsl --install and wsl --install -d Ubuntu)
2. Enter your WSL environment wsl.exe and configure it
3. Update via sudo apt update && sudo apt upgrade -y && sudo snap refresh
4. Continue here: Ubuntu 24.04

MySQL database setup

1. Install the MySQL server:

• Linux/WSL: sudo apt install mysql-server
• Windows: MySQL Community Server

2. connect to it: sudo mysql -u root (Or from outside of WSL: mysql -u root)
3. Create the database: CREATE DATABASE embeddingsearch; use embeddingsearch;
4. Create the user (replace "somepassword! with a secure password): CREATE USER 'embeddingsearch'@'%' identified by "somepassword!"; GRANT ALL ON embeddingsearch.* TO embeddingsearch; FLUSH PRIVILEGES;
5. Create the tables using the CLI tool: cd src/cli; dotnet build and bin/Debug/net8.0/cli -h $mysql_ip -p $mysql_port -U $mysql_username -P $mysql_password --database --setup (replace the variables with the actual values)

Configuration

Environments

The configuration is located in src/server/ and conforms to the ASP.NET configuration design pattern, i.e. src/server/appsettings.json is the base configuration, and /src/server/appsettings.Development.json overrides it.

If you plan to use multiple environments, create any appsettings.{YourEnvironment}.json (e.g. Development, Staging, Prod) and set the environment variable DOTNET_ENVIRONMENT accordingly on the target machine.

Setup

If you just installed the server and want to configure it:

1. Open src/server/appsettings.Development.json
2. Change the password in the "SQL" section (pwd=<your password goes here>;)
3. If your Ollama instance does not run locally, update "OllamaURL" to point at your Ollama instance.
4. If you plan on using the server in production:
   1. Set the environment variable DOTNET_ENVIRONMENT to something that is not "Development". (e.g. "Prod")
   2. Rename the appsettings.Development.json - replace "Development" with whatever you chose. (e.g. "Prod")
   3. Set API keys in the "ApiKeys" section (generate keys using the uuid command on Linux)

API

Accessing the api

Once started, the server's API can be comfortably be viewed and manipulated via swagger.

By default it is accessible under: http://localhost:5146/swagger/index.html

To make an API request from within swagger:

1. Open one of the actions ("GET" / "POST")
2. Click the "Try it out" button. The input fields (if there are any for your action) should now be editable.
3. Fill in the necessary information
4. Click "Execute"

Restricting access

API keys do not get checked in Development environment!

Set up a non-development environment as described in Configuration>Setup to enable API key authentication.
