# FastAPI-DLS Minimal Delegated License Service (DLS). Compatibility tested with official DLS 2.0.1. This service can be used without internet connection. Only the clients need a connection to this service on configured port. [[_TOC_]] # Setup (Service) ## Docker Docker-Images are available here: - [Docker-Hub](https://hub.docker.com/repository/docker/collinwebdesigns/fastapi-dls): `collinwebdesigns/fastapi-dls:latest` - [GitLab-Registry](https://git.collinwebdesigns.de/oscar.krause/fastapi-dls/container_registry): `registry.git.collinwebdesigns.de/oscar.krause/fastapi-dls/main:latest` **Run this on the Docker-Host** ```shell WORKING_DIR=/opt/docker/fastapi-dls/cert mkdir -p $WORKING_DIR cd $WORKING_DIR # create instance private and public key for singing JWT's openssl genrsa -out $WORKING_DIR/instance.private.pem 2048 openssl rsa -in $WORKING_DIR/instance.private.pem -outform PEM -pubout -out $WORKING_DIR/instance.public.pem # create ssl certificate for integrated webserver (uvicorn) - because clients rely on ssl openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout $WORKING_DIR/webserver.key -out $WORKING_DIR/webserver.crt ``` **Start container** To test if everything is set up properly you can start container as following: ```shell docker volume create dls-db docker run -e DLS_URL=`hostname -i` -e DLS_PORT=443 -p 443:443 -v $WORKING_DIR:/app/cert -v dls-db:/app/database collinwebdesigns/fastapi-dls:latest ``` **Docker-Compose / Deploy stack** Goto [`docker-compose.yml`](docker-compose.yml) for more advanced example (with reverse proxy usage). ```yaml version: '3.9' x-dls-variables: &dls-variables DLS_URL: localhost # REQUIRED, change to your ip or hostname DLS_PORT: 443 LEASE_EXPIRE_DAYS: 90 DATABASE: sqlite:////app/database/db.sqlite services: dls: image: collinwebdesigns/fastapi-dls:latest restart: always environment: <<: *dls-variables ports: - "443:443" volumes: - /opt/docker/fastapi-dls/cert:/app/cert - dls-db:/app/database volumes: dls-db: ``` ## Debian/Ubuntu (manual method using `git clone`) Tested on `Debian 11 (bullseye)`, Ubuntu may also work. **Install requirements** ```shell apt-get update && apt-get install git python3-venv python3-pip ``` **Install FastAPI-DLS** ```shell WORKING_DIR=/opt/fastapi-dls mkdir -p $WORKING_DIR cd $WORKING_DIR git clone https://git.collinwebdesigns.de/oscar.krause/fastapi-dls . python3 -m venv venv source venv/bin/activate pip install -r requirements.txt deactivate chown -R www-data:www-data $WORKING_DIR ``` **Create keypair and webserver certificate** ```shell WORKING_DIR=/opt/fastapi-dls/app/cert mkdir $WORKING_DIR cd $WORKING_DIR # create instance private and public key for singing JWT's openssl genrsa -out $WORKING_DIR/instance.private.pem 2048 openssl rsa -in $WORKING_DIR/instance.private.pem -outform PEM -pubout -out $WORKING_DIR/instance.public.pem # create ssl certificate for integrated webserver (uvicorn) - because clients rely on ssl openssl req -x509 -nodes -days 3650 -newkey rsa:2048 -keyout $WORKING_DIR/webserver.key -out $WORKING_DIR/webserver.crt chown -R www-data:www-data $WORKING_DIR ``` **Test Service** This is only to test whether the service starts successfully. ```shell cd /opt/fastapi-dls/app su - www-data -c "/opt/fastapi-dls/venv/bin/uvicorn main:app --app-dir=/opt/fastapi-dls/app" ``` **Create config file** ```shell cat </etc/fastapi-dls/env DLS_URL=127.0.0.1 DLS_PORT=443 LEASE_EXPIRE_DAYS=90 DATABASE=sqlite:////opt/fastapi-dls/app/db.sqlite EOF ``` **Create service** ```shell cat </etc/systemd/system/fastapi-dls.service [Unit] Description=Service for fastapi-dls After=network.target [Service] User=www-data Group=www-data AmbientCapabilities=CAP_NET_BIND_SERVICE WorkingDirectory=/opt/fastapi-dls/app EnvironmentFile=/etc/fastapi-dls/env ExecStart=/opt/fastapi-dls/venv/bin/uvicorn main:app \\ --env-file /etc/fastapi-dls/env \\ --host \$DLS_URL --port \$DLS_PORT \\ --app-dir /opt/fastapi-dls/app \\ --ssl-keyfile /opt/fastapi-dls/app/cert/webserver.key \\ --ssl-certfile /opt/fastapi-dls/app/cert/webserver.crt \\ --proxy-headers Restart=always KillSignal=SIGQUIT Type=simple NotifyAccess=all [Install] WantedBy=multi-user.target EOF ``` Now you have to run `systemctl daemon-reload`. After that you can start service with `systemctl start fastapi-dls.service` and enable autostart with `systemctl enable fastapi-dls.service`. ## Debian/Ubuntu (using `dpkg`) Packages are available here: - [GitLab-Registry](https://git.collinwebdesigns.de/oscar.krause/fastapi-dls/-/packages) Successful tested with: - Debian 12 (Bookworm) (works but not recommended because it is currently in *testing* state) - Ubuntu 22.10 (Kinetic Kudu) Not working with: - Debian 11 (Bullseye) and lower (missing `python-jose` dependency) - Ubuntu 22.04 (Jammy Jellyfish) (not supported as for 15.01.2023 due to [fastapi - uvicorn version missmatch](https://bugs.launchpad.net/ubuntu/+source/fastapi/+bug/1970557)) **Run this on your server instance** First go to [GitLab-Registry](https://git.collinwebdesigns.de/oscar.krause/fastapi-dls/-/packages) and select your version. Then you have to copy the download link of the `fastapi-dls_X.Y.Z_amd64.deb` asset. ```shell apt-get update FILENAME=/opt/fastapi-dls.deb wget -O $FILENAME dpkg -i $FILENAME apt-get install -f --fix-missing ``` Start with `systemctl start fastapi-dls.service` and enable autostart with `systemctl enable fastapi-dls.service`. ## ArchLinux (using `pacman`) **Shout out to `samicrusader` who created build file for ArchLinux!** Packages are available here: - [GitLab-Registry](https://git.collinwebdesigns.de/oscar.krause/fastapi-dls/-/packages) ```shell pacman -Sy FILENAME=/opt/fastapi-dls.pkg.tar.zst url -o $FILENAME pacman -U --noconfirm fastapi-dls.pkg.tar.zst ``` Start with `systemctl start fastapi-dls.service` and enable autostart with `systemctl enable fastapi-dls.service`. ## Let's Encrypt Certificate If you're using installation via docker, you can use `traefik`. Please refer to their documentation. Note that port 80 must be accessible, and you have to install `socat` if you're using `standalone` mode. ```shell acme.sh --issue -d example.com \ --cert-file /etc/fastapi-dls/webserver.donotuse.crt \ --key-file /etc/fastapi-dls/webserver.key \ --fullchain-file /etc/fastapi-dls/webserver.crt \ --reloadcmd "systemctl restart fastapi-dls.service" ``` After first success you have to replace `--issue` with `--renew`. # Configuration | Variable | Default | Usage | |------------------------|----------------------------------------|------------------------------------------------------------------------------------------------------| | `DEBUG` | `false` | Toggles `fastapi` debug mode | | `DLS_URL` | `localhost` | Used in client-token to tell guest driver where dls instance is reachable | | `DLS_PORT` | `443` | Used in client-token to tell guest driver where dls instance is reachable | | `TOKEN_EXPIRE_DAYS` | `1` | Client auth-token validity (used for authenticate client against api, **not `.tok` file!**) | | `LEASE_EXPIRE_DAYS` | `90` | Lease time in days | | `LEASE_RENEWAL_PERIOD` | `0.15` | The percentage of the lease period that must elapse before a licensed client can renew a license \*1 | | `DATABASE` | `sqlite:///db.sqlite` | See [official SQLAlchemy docs](https://docs.sqlalchemy.org/en/14/core/engines.html) | | `CORS_ORIGINS` | `https://{DLS_URL}` | Sets `Access-Control-Allow-Origin` header (comma separated string) \*2 | | `SITE_KEY_XID` | `00000000-0000-0000-0000-000000000000` | Site identification uuid | | `INSTANCE_REF` | `10000000-0000-0000-0000-000000000001` | Instance identification uuid | | `ALLOTMENT_REF` | `20000000-0000-0000-0000-000000000001` | Allotment identification uuid | | `INSTANCE_KEY_RSA` | `/cert/instance.private.pem` | Site-wide private RSA key for singing JWTs \*3 | | `INSTANCE_KEY_PUB` | `/cert/instance.public.pem` | Site-wide public key \*3 | \*1 For example, if the lease period is one day and the renewal period is 20%, the client attempts to renew its license every 4.8 hours. If network connectivity is lost, the loss of connectivity is detected during license renewal and the client has 19.2 hours in which to re-establish connectivity before its license expires. \*2 Always use `https`, since guest-drivers only support secure connections! \*3 If you recreate instance keys you need to **recreate client-token for each guest**! # Setup (Client) **The token file has to be copied! It's not enough to C&P file contents, because there can be special characters.** Successfully tested with this package versions: - `14.3` (Linux-Host: `510.108.03`, Linux-Guest: `510.108.03`, Windows-Guest: `513.91`) - `14.4` (Linux-Host: `510.108.03`, Linux-Guest: `510.108.03`, Windows-Guest: `514.08`) - `15.0` (Linux-Host: `525.60.12`, Linux-Guest: `525.60.13`, Windows-Guest: `527.41`) ## Linux ```shell curl --insecure -L -X GET https:///client-token -o /etc/nvidia/ClientConfigToken/client_configuration_token_$(date '+%d-%m-%Y-%H-%M-%S').tok service nvidia-gridd restart nvidia-smi -q | grep "License" ``` ## Windows Download file and place it into `C:\Program Files\NVIDIA Corporation\vGPU Licensing\ClientConfigToken`.

## Windows ### Required cipher on Windows Guests (e.g. managed by domain controller with GPO) It is required to enable `SHA1` (`TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA_P521`) in [windows cipher suite](https://learn.microsoft.com/en-us/windows-server/security/tls/manage-tls). ### Multiple Display Container LS Instances On Windows on some machines there are running two or more instances of `NVIDIA Display Container LS`. This causes a problem on licensing flow. As you can see in the logs below, there are two lines with `NLS initialized`, each prefixed with `<1>` and `<2>`. So it is possible, that *daemon 1* fetches a valid license through dls-service, and *daemon 2* only gets a valid local license.
