M1Mac上的DotnetTestcontainers有问题吗？

是的，M1 Mac上的Dotnet Testcontainers有问题。这是由于Testcontainers使用的是Docker Desktop，而Docker Desktop还不支持M1芯片的机器。要解决这个问题，需要使用Rosetta 2来运行Docker。

代码示例：

dotnet add package --prerelease TestContainers.Microsoft.Hosting

using Microsoft.VisualStudio.TestTools.UnitTesting;
using TestContainers.Container.Abstractions;
using TestContainers.Container.Abstractions.Images;
using TestContainers.Container.Abstractions.Models;
using TestContainers.Container.Abstractions.WaitStrategies;
using TestContainers.Container.Abstractions.Hosting;
using TestContainers.Container.DevOps.Pipelines.Dockerfile;

namespace TestProject1
{
    [TestClass]
    public class UnitTest1
    {
        private static IContainerProvider _containerProvider;

        [ClassInitialize]
        public static void ClassInitialize(TestContext testContext)
        {
            _containerProvider = new DockerfileContainerProvider()
                .WithDockerfile(@"FROM mcr.microsoft.com/mssql/server:2017-latest

ENV ACCEPT_EULA=Y
ENV SA_PASSWORD=yourStrong(!)Password
ENV MSSQL_PID=Developer

COPY [" + "\"TestDb.bak\", \"/var/opt/mssql/data/\"]" + @"

    -Q 'RESTORE DATABASE TestDb FROM DISK = \"/var/opt/mssql/data/TestDb.bak\" WITH MOVE \"TestDb\" TO \"/var/opt/mssql/data/TestDb.mdf\", MOVE \"TestDb_log\" TO \"/var/opt/mssql/data/TestDb_log.ldf\";'" + @"
                ")
                .WithImageName("testcontainerstest:mssqlserver")
                .WithExposedPort(1433)
                .WithLabel("containerName", "mssqlserver")
                .WithWaitStrategy(Wait.ForUnixContainer().UntilPortIsAvailable(1433));

            _containerProvider.Register().Wait();
        }

        [TestMethod]
        public void TestMethod1()
        {
            var uri = _containerProvider.GetHostEndpoint("1433/tcp").Uri;

            // connect to SQL server instance
        }
    }
}
