Dependent healthchecks

[Alex Todorov (alex-todorov-j2)]

I added a RabbitMQ dependency to the apiservice project:

var apiService = builder.AddProject<Projects.AspireStarterApp_ApiService>("apiservice")
    .WithReference(msgBroker);

Then stopped the container for RabbitMQ in Docker and went to the /health endpoint of apiservice hoping it would now report Unhealthy. But it still returned Healthy.

My question: is there a way to configure .NET Aspire for nested healthchecks like this? (You could go with your own healthcheck package/code but I'm curious what .NET Aspire has to offer.)

If you use the Aspire Component for RabbitMQ and add the RabbitMQ client using the method provided by it, you should get a health check added for it. See https://learn.microsoft.com/dotnet/aspire/messaging/rabbitmq-client-component?tabs=dotnet-cli#health-checks for more details.

True, I was missing the same var msgBroker = builder.AddRabbitMQ("messaging"); in the apiservice Program class. It is a step in the article. My bad!

With that added, the apiservice /healthcheck returns Unhealthy if RMQ is down. And it reports the same in the Console logs.
