Nightly not nightly?

Somehow, when I use your image nightly-slim, I end up with rustc --version yielding 1.15.0-nightly, whereas rustup gives me 1.16.0-nightly on my mac.

Shouldn't it be always fetching the latest upon build?

Thanks for the great images btw!

If you look inside the Dockerfile, it's running rustup with the version set to nightly. This will always yield the latest version of rust. Try updating your container

I am getting this issue as well. I installed docker and this image for the first time today, RUN rustc --version gives me 1.17.0 whereas the current nightly version today is 1.21.0.
