A CI/CD Pipeline for Serverless Cloudflare Workers

In this tutorial, we’ll learn how to use Semaphore to deploy serverless functions to Cloudflare. With serverless functions, developers can run production-ready applications that scale without having to manage infrastructure.

Cloudflare Workers live on the edge of their network and can intercept and modify HTTP requests. Consequently, we can use them to augment our websites, create new applications and services, or redirect and load-balance traffic.

As you transition from the “server full” to the serverless mindset, you’ll stop fretting about the how and start thinking in terms of the what . Your focus can move from managing infrastructure—whether they are servers or containers—to writing code. It’s on the cloud provider to figure out how to run it.

In this post, we’ll learn how to use Semaphore CI/CD to test and deploy a serverless function to Cloudflare.
