@tboerger any idea?

[tboerger]

Please update also the base image for rpi to a proper 3.5 image

[PeterDaveHello]

@tboerger I don't think it has v3.5, the last time it's updated was 9 months ago:
https://hub.docker.com/r/hypriot/rpi-alpine-scratch/tags/

Did I miss anything?

[sapk]

multiarch/alpine could be used as a replacement of hypriot ?

[PeterDaveHello]

Maybe, but it'll be another issue?

[sapk]

I think that if one image of gitea is updated the others should have the same treatment in the same time (same PR) to be consistent. We just have to clarify which new base for arm and I am maybe a little to new in the maintainers to choose the one ^^.

[tboerger]

The mulriarch image sounds good.

Fix vs. improvement? First update to 3.5. Later change it to improve more architectures?

It's all about using a more up2date base image. So nothing really about more architectures to support.

[PeterDaveHello]

@tboerger so you want me to change rpi base image here?

[sapk]

@PeterDaveHello I wouldn't talk for @tboerger but he say that multiarch is good so please update multiarch/alpine:armhf-v3.5 for .rpi and multiarch/alpine:aarch64-v3.5 for .aarch64

That's exactly what I mean :)
