## What is it?

A Provider for Ocelot which provides a Round Robin Load Balancer with API Nodes Health Checking.

## Status

The provider is in alpha stage but should be usable. It has been tested as part of my cluster setup.

This project is open to pull requests.

## Setup

The setup is comparable to other Ocelot providers. Its target framework is netcoreapp3.1.

### Install nuget package

```

dotnet add package Ocelot.GracefulLoadBalancer --version 0.0.2-alpha

```

or visit the nuget for other options on: https://www.nuget.org/packages/Ocelot.GraceFulLoadBalancer

### Adding the provider to your project

The following shows a typical configuration a cluster for a 3 Node API Endpoint setup on the balancer 

and should be easily adaptable to your own settings. I assume you already have basic knowledge of Ocelot.

Note! That I am using the YAML Configuration provider from NetEscapedes in the sample project instead of

configuring via JSON. If you prefer JSON it should be easy to convert it manually or with a YAML to JSON converter.

Consider the following configuration:

```YAML

Routes:

- DownstreamPathTemplate: "/api/auth/{everything}"

  DownstreamScheme: http

  DownstreamHostAndPorts:

  - Host: 192.168.178.88

    Port: 8800

  - Host: 192.168.178.90

    Port: 8800

  - Host: 192.168.178.91

    Port: 8800

  LoadBalancerOptions:

    Type: GracefulLoadBalancer

  UpstreamPathTemplate: "/api/auth/{everything}"

  UpstreamHttpMethod:

  - Get

```

The `LoadBalancer` options simply point to the implementation. You can add the loadbalancer as follows:

```csharp

builder.ConfigureServices(s => {

    s.AddOcelot().AddGracefulLoadBalancer();

})

```
