You cannot copy over /etc/hosts. Docker provides the container with a custom /etc/hosts file.

You can overwrite this by using -v /some/file:/etc/hosts when creating the container. You can also write to the file from inside the container. You can also use the --add-host option when creating the container to add your own custom entries.

But you cannot copy over it. This is not something we can support, so closing.
