Support for ARM 32 bit (armhf )
Proposal
Hi All,
Thank you for the amazing job you have done to develop KEDA. I just tried to install KEDA on my Raspberry Pi cluster that uses Kubernetes K3s, but apparently KEDA docker images are not built for ARM 32-bit architecture (it already supports ARM 64-bit). I would appreciate it if you would consider this support.
Use-Case
I would like to run KEDA on devices with ARM 32-bit architecture.
Anything else?
No response
I have checked the supported arch of gcr.io/distroless/static:nonroot and also supports arm so I'd say that it's doable. My only concern is that we don't have any machine with that arch to run at least the smoke test...
WDYT @kedacore/keda-core-contributors ?
I have tried building it from my local and at least it can be built only adding the new target
We can try to ask CNCF if they have some spare machine to cover this?
Does it make sense? I mean, do we need to run smoke test as a requirement for this arch? AFAIK, it's not an arch to use in prod. I agree that test everything is always better, but if it's not doable I'm not sure if it's a blocker in this case. But maybe I'm wrong and it's used in prod, in any case, we could add a disclaimer for it

Yes, everything that we offer should be verified and tested IMO.

Who says this will not be used in production? 😄 We cannot make that assumption if we offer it as part of our image imo.

💯
Did you check if Equinix has ARM 32 machines already?
I have checked and I think that they don't offer it but I'm not 100% sure because I can't see our current machine type
I have reviewed the previous request for ARM64 and checking the catalogue there, there isn't any ARM32 machine in Equinix. I have opened a ticket for it
They answered me redirecting me to the CNCF repository and there they request the server model from Equinix catalogue, but Equinix doesn't have arm32 machines. I'll check if we can use emulation for running this smoke tests but checking, kind doesn't have either an image for arm32, we should compile it if we want use. I think that we could give another try in few months, but atm it could be a lot of work
To confirm as well, newer Raspberry Pis support ARM64 correct? Not saying we shouldn't do this if we can, but wondering if this is a point-in-time limitations and hopefully newer gens will be good with current ARM bits
At very least wondering if that could potentially lower this from "high pri" in roadmap
lol, you're right @jeffhollan (I totally forgot this) , this is locked indeed due to hardware limitations that we have to test them. Maybe we could emulate ARM32 on the ARM machine to support it, but for sure this shouldn't be high prio
