Cloud Health Connect provides a Koa Middleware based on
[Cloud Health](https://github.com/CloudNativeJS/cloud-health).
The following endpoints are provided to monitor services and applications on Kubernetes:

- Health Endpoint
- Liveness Endpoint
- Readiness Endpoint

## Usage

```typescript
import * as Koa from 'koa';
import * as health from '@cloudnative/health';
import { HealthEndpoint, ReadinessEndpoint, LivenessEndpoint } from 'koa-health-check';

const healthcheck = new health.HealthChecker();
const koa = new Koa();

koa.all('/live', LivenessEndpoint(healthcheck));
koa.all('/ready', ReadinessEndpoint(healthcheck));
koa.all('/health', HealthEndpoint(healthcheck));
```
