Review comment:
fair enough, but there are multi-stage builds where I think it's doing something like:
```dockerfile
ARG CENTOS_VERSION=8
FROM centos:${CENTOS_VERSION}
ARG CENTOS_VERSION=8
# ...
ENV CENTOS_VERSION=${CENTOS_VERSION}
```
could you instead do
```dockerfile
ARG CENTOS_VERSION=8
ENV CENTOS_VERSION=${CENTOS_VERSION}
FROM centos:${CENTOS_VERSION}
```
?

Review comment:
It's not a duplicate `ARG`. `ARG` is the only Dockerfile instruction that is allowed before `FROM`, and in order to pull the image `centos:${CENTOS_VERSION}` where `CENTOS_VERSION` is a build arg, `ARG` needs to go before `FROM`.
However, build args (unlike environment variables) are not accessible in build stages after the one where the build arg is declared. So, in order to be able to use `CENTOS_VERSION` *after* the `FROM` instruction, a second `ARG` instruction is required for `CENTOS_VERSION`.

Review comment:
Nope because `ENV` cannot come before the first `FROM`. If it does, you'll get an error like `No build stage in current context`.
From [the documentation](https://docs.docker.com/engine/reference/builder/#from):
> - `ARG` is the only instruction that may precede `FROM` in the `Dockerfile`.
See [Understand how ARG and FROM interact](https://docs.docker.com/engine/reference/builder/#understand-how-arg-and-from-interact).
