What happened?

I sometime reach the timeout of 100 seconds when trying to start a new container, I checked the code and couldn't find a straightforward way to modify the timeout

Relevant log output

Class Initialization method FunctionalTests.HealthControllerTests.InitContainer threw exception. System.OperationCanceledException: System.OperationCanceledException: The operation was canceled..

Additional information

I use this code to build the container:

    new ContainerBuilder()...Build()

for now to bypass this issue I modify the timeout with a bit of reflection:

    private static void RemoveDockerClientTimeout(IContainer container)
    {
        Assembly testcontainersAssembly = Assembly.Load("Testcontainers");

        object testContainersclient = typeof(DockerContainer)
            .GetField("_client", BindingFlags.NonPublic | BindingFlags.Instance)
            .GetValue(container);

        object containerOperations = testcontainersAssembly
            .GetType("DotNet.Testcontainers.Clients.TestcontainersClient")
            .GetProperty("Container", BindingFlags.Public | BindingFlags.Instance)
            .GetValue(testContainersclient);

        DockerClient dockerClient = (DockerClient)testcontainersAssembly
            .GetType("DotNet.Testcontainers.Clients.DockerApiClient")
            .GetProperty("Docker", BindingFlags.NonPublic | BindingFlags.Instance)
            .GetValue(containerOperations);

        dockerClient.DefaultTimeout = Timeout.InfiniteTimeSpan;
    }

and then I run

    await container.StartAsync().ConfigureAwait(false);

This sounds very unusual. The HTTP request should get its response fairly quickly. I would expect something else is causing an issue. A few seconds is already a lot. I haven't seen something like this before. Although, it looks like you are depending on Windows containers (on purpose?), which I haven't used for a while now. Have you tried the Linux engine? Do you run into similar issues?

To override the default Docker client configuration, you can pass a custom Docker endpoint configuration to the builder (you can use the custom Docker endpoint as a global configuration too without assigning it to every builder configuration). Here is a quick example:

_ = new ContainerBuilder()
    .WithDockerEndpoint(new MyCustomDockerEndpoint())
    .Build();

private sealed class MyCustomDockerEndpoint : IDockerEndpointAuthenticationConfiguration
{
    public Uri Endpoint => TestcontainersSettings.OS.DockerEndpointAuthConfig.Endpoint;

    public Credentials Credentials => TestcontainersSettings.OS.DockerEndpointAuthConfig.Credentials;

    public DockerClientConfiguration GetDockerClientConfiguration(Guid sessionId = default)
    {
        return new DockerClientConfiguration(Endpoint, Credentials, TimeSpan.FromMinutes(5), TimeSpan.FromMinutes(5), ReadOnlyDictionary<string, string>.Empty);
    }
}
