Next.js deployment using Docker

To deploy a Next.js project to a Windows Server running IIS using Docker, you can follow these steps:

Build a Docker image for your Next.js application using a Dockerfile. Here's an example Dockerfile:
bash
# Use the official Node.js runtime as a parent image
FROM node:14

# Set the working directory to /app
WORKDIR /app

# Copy package.json and package-lock.json to the working directory
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the rest of the application code to the working directory
COPY . .

# Build the application for production
RUN npm run build

# Expose port 3000
EXPOSE 3000

# Start the application
CMD ["npm", "start"]
Create a docker-compose.yml file that defines the Docker services for your application. Here's an example:
yaml
Copy code
version: "3"

services:
  app:
    build: .
    ports:
      - "3000:3000"
This configuration will create a Docker container for your Next.js application, and expose port 3000 to the host machine.

Start the Docker container using the following command:
Copy code
docker-compose up -d
This will start the Docker container in detached mode.

Create a new website in IIS and configure it to use a reverse proxy to route traffic to the Docker container. You can do this by following these steps:
Open IIS Manager and navigate to the server node.
Right-click the "Sites" folder and select "Add Website".
Configure the website with the following settings:
Site name: The name of your website.
Physical path: Any valid directory on the server.
Binding: Configure a binding for your website (e.g. http on port 80).
Right-click the website and select "URL Rewrite".
Click "Add Rule" and select "Reverse Proxy".
Configure the reverse proxy with the following settings:
Inbound rules: {REQUEST_URI}.
Outbound rules: {RESPONSE_BODY}.
Backend URL: http://app:3000.
Add the rule and save your changes.
Navigate to the URL of your website in a web browser to confirm that your Next.js application is running correctly.
That's it! You should now have a working Next.js application deployed to your Windows Server running IIS using Docker.
