 ## Production Deployment to a Cloud Host (DigitalOcean Droplet)
 
-For production deployments (such as to a DigitalOcean Droplet), we avoid using `--network="host"`. Instead, we deploy both the database and the application container to a shared, user-defined Docker bridge network named **`dockernet`**. This provides secure internal DNS resolution and container isolation.
+For production deployments (such as to a DigitalOcean Droplet), the application is fully containerized and configured via standard environment variables. 
 
-### 1. Create the Isolated Docker Network
-On your Droplet, create the bridge network:
+The application is completely decoupled from the underlying hosting, networking, and database infrastructure. You are responsible for provisioning the database and supplying the connection configuration.
+
+### 1. Build the Application Container
+Build the application Docker image:
 ```bash
-docker network create dockernet
-```
-
-### 2. Build and Run the Database Infrastructure
-Build the custom MongoDB infrastructure image using the dedicated `Infra.DockerFile`:
-```bash
-# 1. Build the database image
-docker build -t stick-db -f Infra.DockerFile .
-
-# 2. Run the database container on 'dockernet' with host persistence
-docker run --name stick-mongodb \
-  --network dockernet \
-  -v /var/lib/mongodb/data:/data/db \
-  -d \
-  stick-db
-```
-*Note: The database container is named `stick-mongodb`. Other containers on `dockernet` can now resolve this container using `mongodb://stick-mongodb:27017`.*
-
-### 3. Build and Deploy the Application Container
-Build the main application image and launch it on the same network:
-```bash
-# 1. Build the application image
 docker build -t stick-app .
+```
 
-# 2. Run the application container, linking to the database using its container name
-docker run --name stick-app-container \
-  --network dockernet \
+### 2. Deploy the Application Container
+Run the container on your target Docker network, providing the connection details to your pre-existing MongoDB database container through environment variables:
+```bash
+docker run -d \
+  --name stick-app-container \
+  --network your-docker-network \
   -p 80:3007 \
-  -e DATABASE_URL="mongodb://stick-mongodb:27017" \
+  -e DATABASE_URL="mongodb://your-mongodb-host:27017" \
   -e DATABASE_NAME="stick_db" \
   -e JWT_SECRET="your_secure_production_jwt_signing_key_at_least_32_chars_long" \
   -e HOST="0.0.0.0" \
   -e PORT="3007" \
-  -d \
+  --restart unless-stopped \
   stick-app
 ```
-*Note: `-p 80:3007` maps the Droplet's external HTTP port 80 to the application's internal container port 3007.*
+*Note: Adjust the port mapping (`-p`), container name, network name, and `DATABASE_URL` environment variable as necessary to integrate with your custom proxy or container infrastructure.*
