What actually happened?: I can not find any API to copy files/

What did you expect to happen?:

Your best bet is to look at what docker cp actually calls and implement that. This API is just the REST API and not the rest of the docker cli functionality.

If anyone else finds this, the way to do this is to use GetArchiveFromContainerAsync. See the following code sample;

        var getArchiveFromContainerParameters = new GetArchiveFromContainerParameters
        {
            Path = "c:\\myapp\\",
        };

        await Console.Out.WriteLineAsync($"Extracting archive.");
        var getArchiveFromContainerResponse = await client.Containers.GetArchiveFromContainerAsync(createContainerResponse.ID, getArchiveFromContainerParameters, false, CancellationToken.None);

        var path = Path.Combine(@"C:\Users\myAppPath\Output", testName + ".zip" );
        await Console.Out.WriteLineAsync($"Writing archive to {path}.");
        using (var fs = new FileStream(path, FileMode.Create, FileAccess.Write))
        {
            await getArchiveFromContainerResponse.Stream.CopyToAsync(fs);
        }
        await Console.Out.WriteLineAsync($"Completed extracting archive.");

Please keep in mind that the archive stream is a tarball (not a zip).

Any news on this?

Best Implementation I've seen is here, but it fails with large files.
