How do I see the list of files/artifacts available in the docker context when using

pants package ::

if I'm building a

docker_image

?

I don't know of a way to list them, but, and it's been more than a year since I fought this issue, I vaguely remember that there was either a debug message or something part of an error message that you got when trying to access things that don't exist.

There are two ways on top of my mind: a) as @ancient-france-42909 mentions, if you have a

COPY

instruction referencing a non-existing file, the error message will list all files actually available. Or b) run with

--keep-sandboxes=on_failure

and inspect the sandbox for the

docker build

command.
