Installation 🛠️

To get started with Reflow, follow these steps:

1. Clone the Repository:

   git clone https://github.com/CHETHAN562/reflow.git
   cd reflow

2. Install Dependencies: Ensure you have Docker installed on your Linux VPS. You can install it using the following commands:

   sudo apt update
   sudo apt install docker.io
   sudo systemctl start docker
   sudo systemctl enable docker

3. Build the Docker Image: Run the following command to build the Docker image:

   docker build -t reflow .

4. Run the CLI Tool: You can now run the Reflow CLI tool. Check the usage section for details.

Usage 📦

After installation, you can use Reflow to manage your Next.js deployments. Here’s a basic command to get you started:

./reflow deploy <your-nextjs-app>

Replace <your-nextjs-app> with the path to your Next.js application. This command will initiate the deployment process using the Blue-Green strategy.

Command Options

• deploy: Deploy your Next.js application.
• status: Check the status of your current deployment.
• rollback: Roll back to the previous version of your application.

Deployment Strategies 🔄

Blue-Green Deployment

Reflow implements the Blue-Green deployment strategy, which allows you to maintain two identical environments (Blue and Green). You can switch traffic between these environments with minimal downtime. Here’s how it works:

1. Prepare the Green Environment: Deploy your new version to the Green environment.
2. Test the Green Environment: Ensure everything works as expected.
3. Switch Traffic: Once validated, switch traffic from Blue to Green.
4. Rollback if Necessary: If issues arise, revert traffic back to Blue.

This strategy significantly reduces the risk associated with deploying new versions.

Configuration ⚙️

Reflow allows you to customize your deployment settings through a configuration file. Create a file named reflow-config.json in the root of your project. Here’s an example configuration:

{
  "appName": "My Next.js App",
  "port": 3000,
  "dockerImage": "my-nextjs-app:latest",
  "nginxConfig": {
    "serverName": "myapp.com",
    "root": "/usr/share/nginx/html"
  }
}

Configuration Options

• appName: Name of your application.
• port: Port on which your application will run.
• dockerImage: Docker image to use for deployment.
• nginxConfig: Nginx configuration settings.
