When running the aspire dashboard container and dotnet api container separately, I am able to get logs show up on the aspire dashboard.

However, when using docker-compose I don’t get any of the logs come through to the dashboard.

All containers run and I can access the swagger page to make api calls.

The api just creates an order:

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;

namespace TelemetryPrometheus.Controllers
{
    [Route("api/[controller]/[action]")]
    [ApiController]
    public class OrderController(ILogger<OrderController> logger, OrderRepository orderRepository) : ControllerBase
    {
        [HttpPost]
        public async Task<Guid> Create(int userId, [FromBody] Product product, int storeId, int quantity)
        {
            Order newOrder = orderRepository.AddOrder(userId, product, storeId, quantity);
            logger.LogInformation("Order created: {OrderId}", newOrder.Id);

            await orderRepository.SaveAsync();

            return newOrder.Id;
        }
    }


}

program.cs:

builder.Services.AddOpenTelemetry()
    .WithMetrics(MetricsBuilderExtensions =>
    {
        MetricsBuilderExtensions.AddMeter("Microsoft.AspNetCore.Hosting");
        MetricsBuilderExtensions.AddMeter("Microsoft.AspNetCore.Server.Kestrel");
        MetricsBuilderExtensions.AddMeter("System.Net.Http");
        MetricsBuilderExtensions.AddPrometheusExporter();

        MetricsBuilderExtensions.AddOtlpExporter();
    });

builder.Logging.AddOpenTelemetry(options =>
{
    options.AddConsoleExporter();
    options.AddOtlpExporter();
});

Here’s my docker-compose file:
