Hey @btannous, thanks so much for submitting this.

It was my understanding that linux/arm64 was the same as linux/arm64/v8.

I tested your change this morning and the resulting image was identical to the linux/arm64 variant and it built from the cache of the linux/arm64 image.

Furthermore, a docker image inspect showed the architecture as linux/arm64.

What’s the use case for having linux/arm64/v8?

Thanks.

Interesting. Thank you for checking it out quickly, and for the images :)

I’m using Fedora IoT on a Pi 3b+ which uses podman instead of docker.

For some reason it didn’t pull your image as it was looking for arm64/v8. I’m new to this combo, so maybe i’m missing something.

I will try to specify the arm64 variant. I’ll check it out here in a bit.

No worries at all. I'm happy to add linux/arm64/v8 if it solves your problem mate. Just let me know.

So it's looking like the plain arm64 will work with an addtl flag. I'll close the PRs! Sorry for the false alarm, but maybe these comments will help someone running into this issue.

Adding: --override-arch=arm64 seems to work, when podman is trying to look for arm64/v8 specifically.

Thanks for letting me know. I have subbed to the libpod case you opened.

Agree the architecture names are a mess. armel, armhf, armv7l, aarch64, arm64... It is not intuitive at all.
