What happened?

Starting a container using Podman run command in terminal I can mount volumes OK. Attempting to do the same in code like:

new GenericContainer<>(imageRepo + ":" + imageTag)
                .withFileSystemBind("./myMount", "/myMount", BindMode.READ_WRITE)
                .withExposedPorts(9080)
                .withPrivilegedMode(true)
                .withLogConsumer(new Slf4jLogConsumer(LOGGER).withPrefix("Service"));
container.start();

Without the withFileSystemBind it starts OK. With it I get this error in log always:

Unable to mount a file from test host into a running container. This may be a misconfiguration or limitation of your Docker environment. Some features might not work.

I can see that in DockerClientFactory method checkMountableFile it attempts to bind a dummy volume and catches any exception. It then only does log.debug of the message including the exception so I can't see the cause.

How can I get the debug output? Does the Slf4jLogConsumer not capture it?

I am using gradle to build and run tests.

DockerClientFactory.checkMountableFile から開始し、失敗した bind-volume チェックがどのようにログに記録されるかを確認します。その経路を Slf4jLogConsumer および Gradle のテストロギング設定と比較し、基になる例外がどこで利用可能かを特定します。Podman を使って macOS 上で問題を再現した際に、マウント失敗の原因を確認できれば完了です。
