## Service discovery for HAProxy

EasyHAProxy dynamically creates the `haproxy.cfg` based on the labels defined in docker containers.

EasyHAProxy can detect and configure HAProxy automatically on the following platforms:

- Docker

- Docker Swarm

- Kubernetes

## Who is using?

EasyHAProxy is part of some projects:

- Dokku 

- MicroK8s

See detailed instructions on how to install below.

## EasyHAProxy Mission

Easy to set up and low configuration to numerous features. 

## Features

EasyHAProxy will discover the services based on the Docker Tags of the containers running on a Docker host or Docker Swarm cluster and dynamically set up the `haproxy.cfg`. Below, EasyHAProxy main features:

- Support Automatic Certificate Management Environment (ACME) protocol compatible with Let's encrypt and others CA.

- Set your custom SSL certificates

- Balance traffic between multiple replicas

- Set SSL with three different levels of validations and according to the most recent definitions.

- Set up HAProxy to listen to TCP.

- Add redirects.

- Enable/disable Stats on port 1936 with a custom password.

- Enable/disable custom errors.

Also, it is possible to set up HAProxy from a simple Yaml file instead of creating `haproxy.cfg` file.

## How Does It Work?

You don't need to change your current infrastructure and don't need to learn the HAProxy configuration.

The steps are:

- Run the EasyHAProxy container;

- Add some labels to the containers you want to be parsed by EasyHAProxy (see detailed instructions below);

- EasyHAProxy will automatically detect the containers, set up, and reload the HAProxy configurations for you without downtime.

## Detailed Instructions

For detailed instructions on how to use EasyHAProxy, follow the instructions for the platform you want to use:

[![Kubernetes](docs/easyhaproxy_kubernetes.png)](docs/kubernetes.md)

[![Docker Swarm](docs/easyhaproxy_swarm.png)](docs/swarm.md)

[![Docker](docs/easyhaproxy_docker.png)](docs/docker.md)

[![Static](docs/easyhaproxy_static.png)](docs/static.md)

Or you can install using tools:

[![Helm](docs/easyhaproxy_helm.png)](docs/helm.md)

[![MicroK8s](docs/easyhaproxy_microk8s.png)](docs/microk8s.md)

[![Dokku](docs/easyhaproxy_dokku.png)](docs/dokku.md)

## Special Topics

If you already set up the EasyHAProxy, is time to go deeper:

- [Custom SSL](docs/ssl.md)

- [Automatic Certificate Issuing](docs/acme.md) (e.g. Letsencrypt)
