Cannot run on Rpi3B+ aarch64

[121593]

Hello,

I cannot manage to run the project on a Raspberry 3 B+ loaded with RancherOs.

The problem may lie in the architecture resolution : AFAIK arm64v8 images should run on aarch64 labelled architecture [1], but docker says 'platform unsupported'.

I don't have deep docker knowledge, but a manifest may help resolution ?

Which tag are you using ?

All tags are here : https://hub.docker.com/r/joxit/docker-registry-ui/tags

arm64v8 based images can't be used on aarch64 ? Did you ever used a nginx based docker image on your aarch64 Rpi ?

[121593]

I actually tried various tags in case I was misunderstanding their purpose, but was expecting arm64v8-static to work.

I managed to run nginx on the Rpi with an image from linuxserver/docker-nginx, which makes use of Docker manifest :

docker manifest inspect linuxserver/nginx

Ok, thank you for your response.
Can you now tell me if the image arm64v8/nginx works on your device ?

[121593]

Just tested, I does works

[Joxit]

Okay, that's a good news

joxit/docker-registry-ui:arm64v8-static is based on arm64v8/nginx, so this should work too.
I launched a new build for this tag, can you pull again my image and test if it works again ?

[Joxit]

No responses, mark as closed

I see the armv7 tag is marked as amd64
https://hub.docker.com/layers/joxit/docker-registry-ui/arm32v7/images/sha256-939fec39f9dd3828272ca4bf73be5a8c21c0d6177d44c182dbe8ed08eb2cfaa9?context=explore

[Joxit]

Yes, this is normal, when you build a docker on a specific architecture, it will add your architecture as metadata in the image. My images are build by docker hub, and their servers are based on amd64 so it adds amd64 as architecture...
If you check the base image in Dockerfile, it's arm32v7/nginx and they are on the correct architecture.
