is there a way to copy an artifact into the image

[dbieber]

I have a build process that builds some js with webpack (outside of my image), which I'd like to copy into the arm image.
How can I do this?

---

I see there are options for copying out of the image after commands has run (copy_artifact_path and copy_artifact_dest), but I don't see any options for copying things (other than the repo itself) into the image. And I don't see a way to do so from within commands either, since that runs in the image, and I don't know how to copy from outside the image into the image from there.

It looks like I could enable this by adding commands similar to

arm-runner-action/action.yml

Line 219 in 5864a94

sudo cp -Rp ${{ github.workspace }} ${{ steps.mount_image.outputs.mount }}${repository_path}

say at line 221. I could add a new input e.g. inputs.before_commands for commands to run outside the image (but after the repo has already been copied in/mounted) if the maintainers were interested in having that as a feature.

Let me know if there's already an option or another recommended approach that doesn't require modifying the action though.

Trying this out in #124.

One apparent disadvantage of the approach I've taken so far is steps.mount_image.outputs.mount isn't known in non_image_commands. So it isn't obvious where to copy the artifact to.
