People use "Docker-based" all the time but what they mean is that they ship $SOFTWARE in a Docker image. "Docker-based" reads, to me, as if you were doing Inference on AMD cards with Docker somehow, which doesn't make sense.
Yeah, they're using docker to wrap up the software packages, which is what Docker is used for. I don't understand why that confuses you or what you think Docker is otherwise used for.
I'm pretty comfortable with Docker/cgroups/namespaces, I have quite a deep understanding of it. But I read "Docker-based inference" like you literally took Docker code to... do inference? The wording in my opinion doesn't make much sense. It's like saying, I don't know, "Flatpak-based inference" or "SSD-based inference". Semantics.
