--compat-volumes

Handle directories marked using the VOLUME instruction (both in this build, and those inherited from base images) such that their contents can only be modified by ADD and COPY instructions. Any changes made in those locations by RUN instructions will be reverted. Before the introduction of this option, this behavior was the default, but it is now disabled by default.
