# FastAPI-DLS
 | 
						|
 | 
						|
Minimal Delegated License Service (DLS).
 | 
						|
 | 
						|
This service can be used without internet connection.
 | 
						|
Only the clients need a connection to this service on configured port.
 | 
						|
 | 
						|
[[_TOC_]]
 | 
						|
 | 
						|
## ToDo's
 | 
						|
 | 
						|
- provide `.deb` package (WIP)
 | 
						|
- migrate from `dataset` to `sqlalchemy` (WIP)
 | 
						|
- migrate from `fastapi` to `flask`
 | 
						|
- Support http mode for using external https proxy
 | 
						|
 | 
						|
## Endpoints
 | 
						|
 | 
						|
### `GET /`
 | 
						|
 | 
						|
HTML rendered README.md.
 | 
						|
 | 
						|
### `GET /status`
 | 
						|
 | 
						|
Status endpoint, used for *healthcheck*. Shows also current version and commit hash.
 | 
						|
 | 
						|
### `GET /docs`
 | 
						|
 | 
						|
OpenAPI specifications rendered from `GET /openapi.json`.
 | 
						|
 | 
						|
### `GET /-/origins`
 | 
						|
 | 
						|
List registered origins.
 | 
						|
 | 
						|
### `GET /-/leases`
 | 
						|
 | 
						|
List current leases.
 | 
						|
 | 
						|
### `GET /client-token`
 | 
						|
 | 
						|
Generate client token, (see [installation](#installation)).
 | 
						|
 | 
						|
### Others
 | 
						|
 | 
						|
There are some more internal api endpoints for handling authentication and lease process.
 |

## 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 <<EOF >/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 <<EOF >/etc/systemd/system/fastapi-dls.service
 | 
						|

Now you have to run `systemctl daemon-reload`. After that you can start service
 | 
						|
with `systemctl start fastapi-dls.service`.

# Known Issues

## Linux

Currently, there are no known issues.
 | 
						|
 | 
						|
## 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.
