# 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

- Support http mode for using external https proxy (disable uvicorn ssl for using behind proxy)

## Endpoints

### [`GET /`](/)

Redirect to `/-/readme`.

### [`GET /status`](/status) (deprecated: use `/-/health`)

Status endpoint, used for *healthcheck*. Shows also current version and commit hash.

### [`GET /-/health`](/-/health)

Status endpoint, used for *healthcheck*. Shows also current version and commit hash.

### [`GET /-/readme`](/-/readme)

HTML rendered README.md.

### [`GET /-/docs`](/-/docs), [`GET /-/redoc`](/-/redoc)

OpenAPI specifications rendered from `GET /-/openapi.json`.

### [`GET /-/manage`](/-/manage)

Shows a very basic UI to delete origins or leases.

### `GET /-/origins?leases=false`

List registered origins.

| Query Parameter | Default | Usage                                |
|-----------------|---------|--------------------------------------|
| `leases`        | `false` | Include referenced leases per origin |

### `DELETE /-/origins`

Deletes all origins and their leases.

### `GET /-/leases?origin=false`

List current leases.

| Query Parameter | Default | Usage                               |
|-----------------|---------|-------------------------------------|
| `origin`        | `false` | Include referenced origin per lease |

### `DELETE /-/lease/{lease_ref}`

Deletes an lease.

### `GET /client-token`

Generate client token, (see [installation](#installation)).

### Others

There are some more internal api endpoints for handling authentication and lease process.

# 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**

```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**

```yaml
version: '3.9'

x-dls-variables: &dls-variables
  DLS_URL: localhost # REQUIRED
  DLS_PORT: 443
  LEASE_EXPIRE_DAYS: 90
  DATABASE: sqlite:////app/database/db.sqlite

    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 <<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
[Unit]
Description=Service for fastapi-dls
After=network.target

[Service]
User=www-data
Group=www-data

  --proxy-headers

[Install]

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)

**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 <download-url>
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 <download-url>
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`.

### `uvicorn.error:Invalid HTTP request received.`

## 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.
