Introduction

The Hystrix Circuit Breaker Demo project demonstrates how to implement the circuit breaker pattern using Hystrix in a Go application. The circuit breaker pattern is used to prevent cascading failures and to improve the resilience of a system by stopping the flow of requests to a failing service.

Installation

To install and run this demo application, follow these steps:

1. Clone the repository:

   git clone https://github.com/brilianfird/hystrix-circuit-breaker-demo.git
   cd hystrix-circuit-breaker-demo

2. Install the dependencies:

   go mod tidy

Usage

To run the demo application, use the following command:

go run .\cmd\server\main.go

You can then access the application at http://localhost:8080. The application provides endpoints to demonstrate the circuit breaker in action.

Hystrix Dashboard

To visualize the circuit breaker metrics, you can use the Hystrix Dashboard. Follow these steps to set up the dashboard:

1. Run the Hystrix Dashboard using Docker:

   docker run --rm -p 7979:7979 --name hystrix-dashboard steeltoeoss/hystrix-dashboard

2. Open your browser and navigate to http://localhost:7979.

3. Point the dashboard to http://host.docker.internal:8081 to monitor the circuit breaker metrics.

The dashboard will display real-time metrics and help you understand the state of the circuit breakers in the application.
