Aspire & Unhealthy RabbitMQ container

[tleub-ebp]

Hi,

I have a warning that i would like to get rid of on my RabbitMQ container.
I don't understand why it is always on status "Running (Unhealthy)".
I need to check that this container is healthy in order to start my 2 api services, otherwise they are not starting.

If someone have a tip to fix it, it would be awesome :)

Here are the versions:

• Aspire.Host: v9.0.0
• RabbitMQ.Client: 7.0.0

Here is the log of the unhealthy reason:
System.TypeLoadException: Could not load type 'RabbitMQ.Client.IModel' from assembly 'RabbitMQ.Client, Version=7.0.0.0, Culture=neutral, PublicKeyToken=89e7d7c5feba84ce'.
at HealthChecks.RabbitMQ.RabbitMQHealthCheck.CheckHealthAsync(HealthCheckContext context, CancellationToken cancellationToken)
at Microsoft.Extensions.Diagnostics.HealthChecks.DefaultHealthCheckService.RunCheckAsync(HealthCheckRegistration registration, CancellationToken cancellationToken)

Here is the code of my Program.cs of the Aspire Host project:

`var builder = DistributedApplication.CreateBuilder(args);

// Configure SQL Server with existing instance
var sqlServer = builder
.AddSqlServer("coffee-sqlserver")
.WithImageTag("latest")
.WithLifetime(ContainerLifetime.Persistent)
.WithDataVolume()
.WithHttpEndpoint(port: 7000, targetPort: 1433) // Assuming 1433 is the default SQL Server port
.AddDatabase("coffee-sqldb"); // Use existing database

// Configure PostgreSQL with existing instance
var postgres = builder
.AddPostgres("coffee-order-postgresql")
.WithImageTag("latest")
.WithLifetime(ContainerLifetime.Persistent)
.WithDataVolume()
.WithHttpEndpoint(port: 7001, targetPort: 5432)
.WithPgAdmin(); // Assuming 5432 is the default PostGreSQL port

// Connect to existing PostGreSQL databases
var postgresAdminDb = postgres.AddDatabase("coffee-admin-postgresdb");
var postgresDb = postgres.AddDatabase("coffee-order-postgresdb");

var migration = builder.AddProject<Projects.CoffeeShop_MigrationService>("migration")
.WithReference(sqlServer)
.WithReference(postgresDb)
.WithReference(postgresAdminDb)
.WaitFor(postgres)
.WaitFor(postgresAdminDb)
.WaitFor(postgresDb);

var rabbitUser = builder.AddParameter("username", true);
var rabbitPass = builder.AddParameter("password", true);

// Configure RabbitMQ with existing instance
var rabbitBroker = builder
.AddRabbitMQ("coffee-rabbitmq", rabbitUser, rabbitPass)
.WithImageTag("4.0.5")
.WithLifetime(ContainerLifetime.Persistent)
.WithHttpEndpoint(port: 7002, targetPort: 15672)
.WithHttpsEndpoint(port: 8002, targetPort: 15672)
//.WithEnvironment("RABBITMQ_DEFAULT_USER", "admin")
//.WithEnvironment("RABBITMQ_DEFAULT_PASS", "password")
.WithManagementPlugin();

// Configure Redis with existing instance
var cache = builder
.AddRedis("coffee-redis")
.WithImageTag("latest")
.WithRedisInsight()
.WithDataVolume();

// Configure the Admin Service
var adminService = builder.AddProject<Projects.CoffeeShop_AdminService>("adminservice")
.WithHttpEndpoint(port:7004)
.WithHttpsEndpoint(port: 8000)
.WithReference(cache)
.WithReference(migration)
.WithReference(postgresAdminDb)
.WithReference(rabbitBroker)
.WaitFor(migration)
.WaitFor(rabbitBroker);

// Configure the Order Service
var orderService = builder.AddProject<Projects.CoffeeShop_OrderService>("orderservice")
.WithHttpEndpoint(port:7003)
.WithHttpsEndpoint(port: 8001)
.WithReference(cache)
.WithReference(postgresDb)
.WithReference(sqlServer)
.WithReference(migration)
.WithReference(rabbitBroker)
.WaitFor(migration)
.WaitFor(rabbitBroker);

// Configure the Angular Frontend
builder
.AddNpmApp("frontend-angular", "../CoffeeShop.FrontEnd")
.WithHttpEndpoint(port: 7005, env: "PORT")
.WithReference(adminService)
.WithReference(orderService)
.WaitFor(adminService)
.WaitFor(orderService)
.WithExternalHttpEndpoints()
.PublishAsDockerFile(); // This publishes the frontend as a Dockerfile

// Build and run the application
await builder.Build().RunAsync();`

Thanks !

P.S: I need to keep the RabbitMQ.Client in version 7.0.0, but I tried to downgrade to version 6.8.X and it won't work, maybe I have to use MassTransit ?

What does your csproj for the apphost look like

[tleub-ebp]

There you go:

<PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net9.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>

    <UserSecretsId>CoffeeShop.AppHost-4de43b13-be3c-41eb-9475-c7a38f9d152c</UserSecretsId>
</PropertyGroup>

<ItemGroup>
    <ProjectReference Include="..\CoffeeShop.AdminService\CoffeeShop.AdminService.csproj" />

Why do you have these in your apphost project:

    <PackageReference Include="Microsoft.EntityFrameworkCore.Design" Version="9.0.1">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
    <PackageReference Include="RabbitMQ.Client" Version="7.0.0" />

This is a csproj inspired by another project, so everything seems not to be good. I'm deleting thoses lines and it works, thanks

The problem is that

<PackageReference Include="RabbitMQ.Client" Version="7.0.0" />

and

<PackageReference Include="Aspire.Hosting.RabbitMQ" Version="9.0.0" />

are incompatible. See RabbitMQ.Client v7 breaks Aspire.RabbitMQ.Client component (dotnet/aspire#3956) for more info.

If you are using Aspire's Aspire.Hosting.RabbitMQ, you need to be using the version 6.8.* of RabbitMQ.Client. In 9.1 we will be shipping a new package Aspire.Hosting.RabbitMQ.v7, which is compatible with version 7.* of RabbitMQ.Client. Then in Aspire 10.0 the Aspire.Hosting.RabbitMQ package will move to v7. This helps in easing the upgrade so someone can use the new Aspire versions without having to take the breaking changes with RabbitMQ v6 => v7 all in a single update.
