I’m running docker registry V2 with S3 backend, but I need to scale it. How safe it is to provision multiple registry nodes pointing to the same S3 storage? I assume pulls should be okay, but what about pushes? What happens if by chance 2 clients start to push the same image?

I’m wondering if you can share your install notes.
My v.9 startup looks like:
sudo docker run
