# HttpHealthCheckOptions

Properties used to define HTTP Based healthchecks.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/service.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-apprunner-alpha/lib/service.ts#L974)

## Example

```ts
new apprunner.Service(this, 'Service', {
  source: apprunner.Source.fromEcrPublic({
    imageConfiguration: { port: 8000 },
    imageIdentifier: 'public.ecr.aws/aws-containers/hello-app-runner:latest',
  }),
  healthCheck: apprunner.HealthCheck.http({
    healthyThreshold: 5,
    interval: Duration.seconds(10),
    path: '/',
    timeout: Duration.seconds(10),
    unhealthyThreshold: 10,
  }),
});
```

## Properties

- `healthyThreshold`: number = 1 — The number of consecutive checks that must succeed before App Runner decides that the service is healthy.

- `interval`: [Duration](/cdk/api/v2/docs/aws-cdk-lib.Duration.html) = Duration.seconds(5) — The time interval, in seconds, between health checks.

- `path`: string = / — The URL that health check requests are sent to.

- `timeout`: [Duration](/cdk/api/v2/docs/aws-cdk-lib.Duration.html) = Duration.seconds(2) — The time, in seconds, to wait for a health check response before deciding it failed.

- `unhealthyThreshold`: number = 5 — The number of consecutive checks that must fail before App Runner decides that the service is unhealthy.
