sindit 2.0.7

SINTEF Digital Twin Framework

Run backend using Docker Compose

To start the backend run (add the --build flag to build images before starting containers (build from scratch)):

docker-compose up
docker-compose up --build

This will build the GraphDB docker image and the FastAPI docker image.

The GraphDB instance will be available at: localhost:7200

The FastAPI documentation will be exposed at: http://0.0.0.0:9017

Run backend locally

Desription of how to start the backend locally outside docker. The backend consists of a GraphDB database and a FastAPI server.

GraphDB

To start GraphDB, run these scripts from the GraphDB folder:

bash graphdb_install.sh
bash graphdb_preload.sh
bash graphdb_start.sh

To test your graphbd connection run from your base folder (/sindit):

poetry run python run_test.py

Go to localhost:7200 to configure graphdb

API uvicorn server

To start the FastAPI server, run:

poetry run python run_sindit.py

Run using vscode launcher

    "version": "0.2.0",
    "configurations": [

        {
            "name": "Python Debugger: Current File",
            "type": "debugpy",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "cwd": "${workspaceFolder}/src/sindit",
            "env": {
                "PYTHONPATH": "${workspaceFolder}/src"
            },
            "justMyCode": false
        }
    ]
}

Using the API

Authentication

The API requires a valid authentication token for most endpoints. Follow these steps to authenticate and use the API:

1. Generate a Token:

   • Use the /token endpoint to generate an access token.
   • Example curl command:

     curl -X POST "http://127.0.0.1:9017/token" \
     -H "Content-Type: application/x-www-form-urlencoded" \
     -d "username=new_user&password=new_password"
     

   • Replace new_user and new_password with the credentials provided below.

2. Use the Token:

   • Include the token in the Authorization header for all subsequent API calls:

     curl -X GET "http://127.0.0.1:9017/endpoint" \
     -H "Authorization: Bearer your_generated_token_here"
     

3. Access API Documentation:

   • The FastAPI documentation is available at: http://127.0.0.1:9017/docs

Generate New Username and Password

To add a new user, update the fake_users_db in authentication_endpoints.py with the following credentials:

fake_users_db = {
    "new_user": {
        "username": "new_user",
        "full_name": "New User",
        "email": "[e-mail]",
        "hashed_password": "$2b$12$eW5j9GdY3.EciS3oKQxJjOyIpoUNiFZxrON4SXt3wVrgSbE1gDMba",  # Password: new_password
        "disabled": False,
    }
}

To generate a new hashed password, use the Python snippet in password_hash.py. Replace "new_password" with your desired password.
