Yes, it was right, but nowadays Dockerfiles are not specific to Docker. Dockerfiles also work with Buildah & Podman (and there might be other ones in the future) and they have generalized the naming: “Containerfile.”

I am not sure about aliases though... The number of aliases for various type definitions could grow without bounds. Unless it is a very common usage Indexify, my 2 cents would be not to create an alias. But I don't make the call on this.

Introducing alias doesn't work in my opinion, I think it is better to think what the best option is than having many options for the same.
