Feature Request and Question: Background Worker Health Checks

[aligneddev]

I have a few AddHostedService, background worker containers running in Azure Container apps. There are health, liveness and readiness probes I wanted to use.

The document doesn't show an example of using the built in AddHealthChecks.

I have RabbitMQ, Redis, and Ngpsql checks I would like to add. I was wondering if my service lost connection to RabbitMq/Redis if a health check would cause a restart and then possible heal that connection

Question 1: Is ASP.Net required for these health checks and probes?

Question 2: Does .Net Aspire have the capability for probes and health checks for background services, with the Aspire Packages?

Describe the solution you'd like.

I would like to use the built in AddHealthChecks capabilities for a background service.

I would like to see an example in the Microsoft Docs on the best approaches and pro/cons of this approach.

Describe alternatives you've considered.
A clear and concise description of any alternative solutions or features you've considered. is informative using TCP to enable K8s health probes. I believe the same approach would work in ACA. There's a lot of custom code here, Is this the best approach?

Additional context.

    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static HostApplicationBuilder CreateHostBuilder(string[] args)
    {
        var builder = Host.CreateApplicationBuilder(args);
        // a lot of setup and custom code

        builder.Services.AddHostedService<MessageQueueProcessor>();
        return builder;
    }

Thank you.

I did find a Microsoft doc which mentions Kubernetes and a HealthCheckPublisher and will look at that more.

Maybe I just need to use WebApplication.CreateBuilder for my worker service...
