On October 10, 2024, we are excited to announce the launch of hellorest, a minimal REST API designed specifically for developers and DevOps engineers who need a predictable, lightweight service to validate their infrastructure. Whether you are testing a new deployment pipeline, verifying network connectivity, or configuring a load balancer, hellorest provides the simplest possible baseline to ensure your environment is working as expected.

What is hellorest?

hellorest is a trivial “Hello World” service written in Go. It does one thing and does it reliably: it exposes a single GET / endpoint that returns a JSON response: {"hello": "world"}.

To keep it as a pure baseline, any other request paths or HTTP methods result in a standard 404 Not Found response. The service is highly configurable via the PORT environment variable, defaulting to port 8080 if none is provided.

Why it matters

In complex microservice architectures, troubleshooting “it works on my machine” often comes down to networking, ingress rules, or container orchestration issues. When you are debugging a deployment pipeline, you don’t want to be debugging the application code—you want to be debugging the infrastructure.

hellorest eliminates the application variable. By deploying a service with a known, unchanging response, you can instantly determine if your traffic is reaching the pod, if your headers are being stripped by a proxy, or if your health checks are correctly configured.

Getting Started

Getting hellorest up and running is designed to be as frictionless as possible. The project comes with a multi-stage Dockerfile that builds a tiny, secure image based on gcr.io/distroless/base-debian12, ensuring a minimal attack surface and fast pull times.

To get started, you can build the image from the source or pull the release image and deploy it to your environment of choice.

We invite you to integrate hellorest into your testing suite to build more resilient and predictable deployment pipelines.
