<summary><h3>Using docker run</h3></summary>

- ⚠️ `docker ... --rm` option is not suitable for production use because it won't survive a reboot. However, it's okay for quick testing. You need to use --restart=always instead to ensure that it persists.
```bash
# (Optional) Install docker if needed
curl -sSL get.docker.com | sh && sudo usermod -aG docker $(whoami) && logout # then login again

# Prepare application data file tree
cd ~ && mkdir -p obscreen/data/db obscreen/data/uploads && cd obscreen

# Run the Docker container
docker run --restart=always --name obscreen --pull=always \
  -e DEBUG=false \
  -e PORT=5000 \
  -e PLAYER_AUTOSTART_FILE=/app/var/run/play \
  -e SECRET_KEY=ANY_SECRET_KEY_HERE \
  -p 5000:5000 \
  -v ./data/db:/app/data/db \
  -v ./data/uploads:/app/data/uploads \
  -v /dev/null:/app/var/run/play \
  jierka/obscreen:latest

# Get files
cd ~ && git clone https://github.com/jr-k/obscreen.git && cd obscreen

# Install application dependencies
python3 -m venv venv
source ./venv/bin/activate

# 🚨For MacOS users, requirements installation may cause an error but it's ok if only for pysqlite3 package
#   you'll need to install brew and execute command `brew install sqlite3`
pip install -r requirements.txt

# Customize server default values
cp .env.dist .env
```

#### Configure
- Server configuration is editable in `.env` file.
- Application configuration will be available at `http://localhost:5000/settings` page after run.

#### Start server
> ⚠️ Not suitable for production use because it won't survive a reboot. However, it's okay for quick testing. You need to use `systemd` (detailed in next section) to ensure that it persists.
```bash
python ./obscreen.py
```

#### Start server forever with systemd
```bash
cat "$(pwd)/system/obscreen-studio.service" | sed "s#/home/pi#$HOME#g" | sed "s#=pi#=$USER#g" | sudo tee /etc/systemd/system/obscreen-studio.service
sudo systemctl daemon-reload
sudo systemctl enable obscreen-studio.service
sudo systemctl start obscreen-studio.service
```

#### Troubleshoot
```bash
# Watch logs with following command
sudo journalctl -u obscreen-studio -f 
```
