+# EasyHAProxy
+
+[EasyHAProxy](https://easyhaproxy.com/) is an Ingress and Auto Discover service based on HAProxy.
+
+HAProxy is an open-source, high-performance load balancer and reverse proxy designed for TCP and HTTP-based applications. Renowned for its stability, reliability, and performance, it is widely adopted in production environments.
+
+EasyHAProxy combines HAProxy's robustness with seamless service discovery and exposure within Kubernetes clusters. It offers a straightforward method to configure Ingress rules for services.
+Key Features
+
+- Handles and routes HTTP, HTTPS, and TCP traffic (e.g., MySQL server).
+- Supports custom error messages.
+- Integrates Let's Encrypt SSL certificate functionality.
+- Automatically discovers services within the Kubernetes cluster.
+- Facilitates the configuration of Ingress rules for services.
+- Provides load balancing capabilities.
+
+## Install
+
+- Enable the EasyHAProxy in the Digital Ocean marketplace
+- Create a Digital Ocean Load Balance pointing to your Kubernetes Cluster. 
+
+## How to set up your application for EasyHAProxy
+
+You need to add to your application ingress annotations to expose your service to the internet.
+
+```yaml
+kind: Ingress
+metadata:
+  annotations:
+    kubernetes.io/ingress.class: easyhaproxy-ingress
+  .
+  .
+  .
+```
+
+## Additional Resources
+
+For further details about EasyHAProxy, please refer to the [documentation](https://easyhaproxy.com/).
+
+## Troubleshooting
+
+### Check if the EasyHAProxy is running properly
+
+You can install the "Static Http Server"  and define the domain you want to validate as the example below:
+
+```shell
+helm repo add byjg https://opensource.byjg.com/helm
+helm repo update
+helm upgrade --install mysite byjg/static-httpserver \
+    --namespace default \
+    --set "ingress.hosts={www.example.org,example.org}" \
+    --set parameters.title=Welcome
+```
+
+
+### EasyHAProxy Container not Starting
+
+Due to limitations in the HAProxy community edition, EasyHAProxy functions solely as a standalone service, regardless of the number of nodes present.
+
+If the node hosting EasyHAProxy experiences downtime, the service will remain unavailable until the node is operational again.
+
+To restore connectivity, you have the option to deploy or upgrade the EasyHAProxy service.
