How to mount the local filesystem in Testcontainers Cloud?

Consider using the copyFileToContainer and copyFileFromContainer methods instead.

Mounting of files from the local filesystem into containers is not implemented. Consider using the copyFileToContainer and copyFileFromContainer methods instead.

For example, if you have created and started a container:

 GenericContainer myContainer = new GenericContainer(ALPINE_IMAGE).withCommand("top");
 myContainer.start();

You can copy files in both directions like this:

MountableFile mountableFile = MountableFile.forClasspathResource("filename");
myContainer.copyFileToContainer(mountableFile, "/path/in/Docker");

File fromContainer = ...; // create File object
myContainer.copyFileFromContainer("/path/in/Docker", fromContainer.getPath());

You can find more examples of the copyFileToContainer in the FileOperationTests on GitHub.
