I’m planning on setting up a couple Mastodon instances and I was wondering if I could point them to the same S3 bucket for media and profile assets. What I want to accomplish mainly is data not being duplicated. I don’t want each instance to have their own copy of an image from some federated post, I just want them all to reference the same image in some bucket.
Is this how S3 storage in Mastodon functions by default, or if not is there a way to accomplish this? I suspect masto.host does this with their own asset domain but I wasn’t sure if that was built-in functionality or something special they set up for themselves.
