Problem:
I built some relatively large images for two different architectures (~6GB each) using docker buildx build and are using --push to push them up to the repository at the same time.
Since they are large, they take a while, so I'm sitting looking at a console of:
...

That has not moved in around 10 minutes, which is not surprising. But it's hard for me to tell if it's hung or if it's just taking a while, as well as how close to completion it is.
I'd also wondered if it had got stuck at the auth step to be honest.
Proposed Solution:
Have some kind of progress meter display when pushing images, ideally with some kind an indication of % complete, or at least number of layers to go up. docker push does this nicely.
Ideally, would be lovely if it had an estimated time to completion as well 😃
Workarounds:
Only option I have so far - run btop and watch my upload network traffic to see if it's being actively pushed.
