Forgive me if this in the documentation somewhere, but I could not find it.
I am trying to mount a volume with functionality the same as -v in the docker cli. I want to mount the volume, but not actually have it persist after the run is complete. I also need to exclude a few subdirectories of the folder I am mounting. Just to give some color, I am trying to run packer build within the dagger run, so packer will take care of packaging its own container and the container to run packer is not really important.
