Minimal Delegated License Service (DLS).
Compatibility tested with official NLS 2.0.1, 2.1.0, 3.1.0. For Driver compatibility see here.
This service can be used without internet connection. Only the clients need a connection to this service on configured port.

System requirements
- 256mb ram
- 4gb hdd
- maybe IPv6 must be disabled
Tested with Ubuntu 22.10 (EOL!) (from Proxmox templates), actually its consuming 100mb ram and 750mb hdd.
Prepare your system
- Make sure your timezone is set correct on you fastapi-dls server and your client
Docker-Images are available here for Intel (x86), AMD (amd64) and ARM (arm64):
- GitHub-Registry:
ghcr.io/captmicr0/fastapi-dls:latest
The images include database drivers for postgres
, mariadb
and sqlite
.
Run this on the Docker-Host
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:
SQLite Database:
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 ghcr.io/captmicr0/fastapi-dls:latest
Docker-Compose / Deploy stack
See examples

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.

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 |
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 |
<app-dir>/cert/instance.private.pem |
Site-wide private RSA key for singing JWTs *3 |
INSTANCE_KEY_PUB |
<app-dir>/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.
*3 Always use https
, since guest-drivers only support secure connections!
*4 If you recreate instance keys you need to recreate client-token for each guest!
The token file has to be copied! It's not enough to C&P file contents, because there can be special characters.

- Make sure you create a folder in a linux filesystem (BTRFS/XFS/EXT4...), I recommend
/mnt/user/system/nvidia
(this is where docker and libvirt preferences are saved, so it's a good place to have that) - Edit the script to put your

Deletes an lease.
Generate client token, (see installation).
There are many other internal api endpoints for handling authentication and lease process.
Please make sure that fastapi-dls and your guests are on the same timezone!
Maybe you have to disable IPv6 on the machine you are running FastAPI-DLS.

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.

The driver wants to release current leases on shutting down windows. This endpoint needs to be a http endpoint. The error message can safely be ignored (since we have no license limitation :P) and looks like this:
Log example
<1>:NLS initialized
<1>:License acquired successfully. (Info: 192.168.178.110, NVIDIA RTX Virtual Workstation; Expiry: 2023-3-30 23:0:22 GMT)
