local-volume-provisioner for arm

[miguelaeh]

Hi,
I need to configure the local-storage-provisioner for an arm cluster, but the quay.io/external_storage/local-volume-provisioner image does not work on arm devices.
Is it possible to do that? And, if it is, how? Can I get the Dockerfile to change the base image or exists any image for that? Thanks.

Yes, it is possible to do.
We need to build local-volume-provisioner for arm and build an image for it.

Multi-arch images:

• local-volume-provisioner (current) -> local-volume-provisione-amd64
• local-volume-provisioner-amd64
• local-volume-provisioner-arm
• local-volume-provisioner-arm64
• local-volume-provisioner-ppc64le (if necessary)
• local-volume-provisioner-s390x (if necessary)

Hi @cofyc,
thanks for your response. I tried with local-volume-provisioner-arm64 but it seems that this image does not exist because I get the following error:
access to the requested resource is not authorized

[cofyc]

sorry, it's not finished yet, can you wait a few days?

[miguelaeh]

Of course,
sorry I understood that it was already finished.

hi, I've pushed images to my personal repository for testing. Could you try gcr.io/yechengfu-1369/local-volume-provisioner:canary image in your arm cluster and verify if it works?

[miguelaeh]

Hi @cofyc ,
I will test it as soon as I can.
Thank you very much.

[cofyc]

btw, official canary images have been pushed too, you can try quay.io/external_storage/local-volume-provisioner-arm64:canary instead.

Hi @cofyc

I am using the current quay.io/external_storage/local-volume-provisioner:canary (multiarch) on a arm arch. I have exec format error.
How can I be sure the base docker image is the right arch, and check the bin also is ?

[cofyc]

using file utility. I've checked it locally, the arch of /local-provisioner is not right. I'll fix it soon.

[cofyc]

@maitredede The bug is fixed, please try again.

This command docker run -it --entrypoint sh quay.io/external_storage/local-volume-provisioner:canary -c 'apt-get update && apt-get install -y file && file /local-provisioner' will show the binary information. Can you try it on your arm machine?

[maitredede]

@cofyc Thanks, it works :)
The binary informations :

/local-provisioner: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, not stripped

For information, it is a Raspberry Pi 4 with Raspbian. The ARCH is arm32v7. I don't know if there can be differences for local-provisioner, but it may be interesting to be more specific on these plateforms.
