show verbose debug log

[FBIanderson]

When I run this type of Dockerfile

FROM debian
RUN ls -al  / 

I want to know the details of root path of the image, but it will show nothing, is there any option like -v(verbose) to show the full log

Can you provide more information about the problem you're trying to solve, and what you need this information for?

Some (most) of these paths should be considered internal information used by docker and BuildKit, and are not intended to be accessed other than through BuildKit (or docker) itself. Depending on how you're running the build, these paths may also be inside a container or volume (when using a BuildKit instance using a container driver), or may be ephemeral locations only present during the build.

For example, the RUN step may create a new writable mount that's only present for the duration of the RUN step, but no longer afterwards.

Having more insight in the problem you're trying to solve may be useful here to see if there's anything to address / improve.
