Implementing Cloudflare R2 as an Image CDN on your website involves a few steps, from setting up the R2 bucket to configuring your website to serve images from R2. Here’s a step-by-step guide to get you started:
Step 1: Set Up Cloudflare R2
Create a Cloudflare Account (If You Don’t Have One):
Sign up at Cloudflare and log in to your dashboard.
Navigate to R2 Storage:
In the Cloudflare dashboard, go to the “R2” section. If you don’t see it, you may need to enable it under “Workers & KV”.
Create an R2 Bucket:
Click “Create a Bucket” and give your bucket a name. This name will be part of the URL for accessing objects in your bucket.
Ensure that the bucket is set to public access if you want your images to be publicly accessible.
Step 2: Upload Your Images to R2
Upload Directly:
You can upload images directly via the Cloudflare dashboard.
Alternatively, you can use a script or a tool like rclone to upload multiple files.
Organize Your Images:
Consider organizing your images in folders within the R2 bucket for easy management.
Step 3: Configure Custom Domain for SEO-Friendly URLs
Add a Custom Domain to Cloudflare:
In your Cloudflare dashboard, go to “DNS” and add a custom domain or subdomain (e.g., cdn.yourdomain.com) that will serve your images.
Create a Worker (Optional for SEO URLs):
To serve images with friendly URLs, you can create a Cloudflare Worker. This Worker can map requests like cdn.yourdomain.com/image1.jpg to the actual R2 object path.
Example Worker code:
export default {
async fetch(request) {
const url = new URL(request.url);
const key = url.pathname.slice(1); // Remove the leading slash
const r2Object = await R2_BUCKET.get(key);
if (!r2Object) {
return new Response('Image not found', { status: 404 });
}
return new Response(r2Object.body, {
headers: { 'Content-Type': r2Object.httpMetadata.contentType }
});
}
}
Bind the Worker to Your Domain:
Go to “Workers” in Cloudflare and bind your Worker script to the custom domain (e.g., cdn.yourdomain.com).
Step 4: Configure Your Website to Use the R2 CDN
Replace Image URLs:
Update the image URLs on your website to point to your Cloudflare R2 domain or the custom domain you configured (e.g., https://cdn.yourdomain.com/image.jpg).
Set Up Caching:
In the Cloudflare dashboard, configure cache rules to ensure that your images are cached at edge locations. This reduces load times by serving images from a location closest to the user.
Enable Image Optimization (Optional):
Use Cloudflare’s automatic image optimization tools, such as Polish or WebP conversion, to further improve performance.
Step 5: Test and Monitor
Verify Image Delivery:
Visit your website and ensure that images are being served from the R2 bucket via your CDN domain.
Check Performance:
Use tools like Google Lighthouse or GTmetrix to test your website’s performance and ensure that the images are loading quickly.
Monitor Usage:
In the Cloudflare dashboard, monitor your R2 usage, requests, and other metrics to optimize costs and performance.
Example Implementation:
If you want to serve an image from R2 using a custom domain like cdn.yourdomain.com, the image URL might look like:
https://cdn.yourdomain.com/images/photo.jpg
Where images/photo.jpg is the path to the image within your R2 bucket.
By following these steps, you can effectively use Cloudflare R2 as a cost-efficient and scalable Image CDN for your website.
