Can't pull image on aarch64 #135
Description
Activity
There never was a build for aarch64. For this conversion you should be pulling down directly anyway:
singularity pull docker://<uri>Thanks for clarifying.
I was looking to accomplish something like this https://sylabs.io/2023/12/building-arm-containers-with-scs/
(not for any good reason, just futureproofing as i'm publishing all my images in x86 and arm variants these days)my actual command is something more like what's found in the readme.
docker run -v /var/run/docker.sock:/var/run/docker.sock \ -v /tmp/test:/output \ --privileged -t --rm \ quay.io/singularity/docker2singularity \ ubuntu:22.04where ubuntu:22.04 is a stand in for my private image. This runs fine on an an x86 host, but dies on an an arm device with the output listed as like you mentioned this isn't available for aarch64 at this time.
Thanks for the tip, this worked great:
singularity pull docker://ubuntu:22.04 INFO: Converting OCI blobs to SIF format INFO: Starting build...

We can try adding the arm build, but they tend to be very slow on GHA, and using singularity directly is the preferred solution I think.
Unable to find image 'quay.io/singularity/docker2singularity:latest' locally

docker: no matching manifest for linux/arm64/v8 in the manifest list entries.
I don't see any reason why an image wouldn't be able to be built for aarch64 looking at the Dockerfile, it just seems that the runner isn't set up to build arm images and combine them into a single manifest
