Container for Azure EventHubs emulator fails to startup successfully in Podman

[jbparker]

Is there an existing issue for this?

Describe the bug

The local EventHubs emulator does not startup successfully when using the Aspire.Hosting.Azure.EventHubs extension method RunAsEmulator().

Two containers (eventhub and eventhub-storage) are started, but the eventhub container fails with the message Emulator Start up probe Unsuccessful. MetadataStore Health status: Unhealthy BlobStore Health status: Unhealthy.

After failing the health checks, the event hub container eventually exits:

Expected Behavior

EventHubs containers created by Aspire hosting should start, pass health checks, and be accessible for Aspire component usage.

Steps To Reproduce

https://github.com/jbparker/AspireEventHub

Forked from https://github.com/davidfowl/AspireEventHub and updated to use Event Hubs emulator from https://github.com/dotnet/aspire/issues/3412

Exceptions (if any)

The event hub container (eventhubns) logs health check errors:

fail: a.a.aaW[0] Emulator Start up probe Unsuccessful. MetadataStore Health status: Unhealthy BlobStore Health status: Unhealthy fail: Microsoft.Extensions.Diagnostics.HealthChecks.DefaultHealthCheckService[103] Health check Emulator Health Check with status Unhealthy completed after 27907.2647ms with message 'Emulator Start up probe Unsuccessful. MetadataStore Health status: Unhealthy BlobStore Health status: Unhealthy' Retry 1 encountered an exception: Emulator Health Check failed.. Waiting 00:00:00 before next retry. ... (meanwhile, after 2nd retry) An error occurred: Emulator Health Check failed.

Naturally, the EventHubsConsumer and EventHubsApi projects throw exceptions trying to access the emulated Event Hubs namespace.

Of note, the storage container (eventhubns-storage) has logs that show it was able to start successfully:

Azurite Blob service is starting at http://0.0.0.0:10000 Azurite Blob service is successfully listening at http://0.0.0.0:10000 Azurite Queue service is starting at http://0.0.0.0:10001 Azurite Queue service is successfully listening at http://0.0.0.0:10001 Azurite Table service is starting at http://0.0.0.0:10002 Azurite Table service is successfully listening at http://0.0.0.0:10002

.NET Version info

.NET SDK: 8.0.303 Workloads: Aspire 8.1.0/8.0.100 Runtime environment: Windows, 10.0.22631 .NET runtimes: Microsoft.AspNetCore.App 8.0.7, Microsoft.NETCore.App 8.0.7, Microsoft.WindowsDesktop.App 8.0.7

Anything else?

I'm unsure if this is an issue with using Podman or something dealing directly with Azurite/etc and not Aspire.

Using:

• .NET Aspire 8.1 packages/workload
• Podman version 5.1.1
• Visual Studio Enterprise 2022 v17.10.5
