Specifying more extra_inputs like overlays

[nobodyinperson]

Asked in chat:

Is there an more elegant way of specifying an additional --overlay image with datalad containers-add than hard-coding it in --call-fmt and specifying the overlay image as --input in each datalad containers-run?

A little less hard-coding can be achieved by putting the overlay next to the Apptainer/Singularity image and naming it exactly the same just with a suffix (e.g. -overlay.img), then use --call-fmt 'apptainer exec --overlay {img}-overlay.img {img} {cmd}'. Still need to specify the overlay as --input in containers-run though...

It would be helpful if one could do:

datalad containers-add NAME \
   --extra-input containers/overlay.img \
   --call-fmt 'apptainer exec --overlay {imgdir}/overlay.sif {img} {cmd}' \
   -i containers/container.sif
