Type Parameters

T

A resource type that implements IResourceWithEndpoints.

builder: IResourceBuilder<T>

A resource builder.

path: String

The relative path to test.

statusCode: Nullable<Int32>

Examples

This example shows add a HTTPS health check to a backend project to make sure that the front end does not start until the backend is reporting a healthy status based on the return code returned from the "/health" path on the backend server.

var builder = DistributedApplication.CreateBuilder(args);
var backend = builder.AddProject<Projects.Backend>("backend")
                     .WithHttpsHealthCheck("/health");
builder.AddProject<Projects.Backend>("backend")
       .WithReference(backend).WaitFor(backend);

Remarks

This method adds a health check to the health check service which polls the specified endpoint on the resource on a periodic basis. The base address is dynamically determined based on the endpoint that was selected. By default the path is set to "/" and the status code is set to 200.
