ARM64 is it Possible

[macooper59]

Hey there Clemenko,

Thank you for the Video and the article, but I see it is only for the AMD side of things. I am testng it on the Intel/AMD side but I use Raspberry Pi 4/5 & Orange Pi 5s also. I found a link to the curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/arm64/kubectl -o /usr/local/bin/kubectl and I am researching and testing for it. I need some help please. I was wondering if you had any ideas?

Can you point me in the right direction please.
Thank you,
Michael

Hey Michael, Arm is possible. It all depends on what components you want though. Currently Rancher is experimental at best : https://ranchermanager.docs.rancher.com/v2.5/getting-started/installation-and-upgrade/advanced-options/enable-experimental-features/rancher-on-arm64.
Hauler, kubectl and rke2 do support arm. The script can certainly be modified to accommodate for arm.
Is this just for testing/playing?

I can confirm the challenges with Rancher on ARM64 as being consistent with its experimental status. I’ve been testing Rancher in a mixed-node setup with Raspberry Pi 5 devices (ARM) and a Dell Precision laptop (x86_64), all running Ubuntu 24.04 LTS.

When ARM nodes are included, Rancher faces several issues, such as the Multi-Cluster Management Plugins failing to load and the inability to add cloud provider credentials (only S3 is available). Additionally, while Harvester successfully connects to Rancher, it enters an endless creation-deletion loop when attempting to provision VMs through Fleet, which I believe may be related to a TLS handshake error.

The same issues occur in a single-node setup and a fully ARM-based cluster consisting of two Raspberry Pi 5s and one Raspberry Pi 4, all running Ubuntu 24.04 LTS.

I figured as much, I have been having issues with this for at least a year. Thanks for the info, Michael Cooper *Certified Linux Professional* *Docker/Kubernetes Trained* RPi Hobby Blog <http://www.rpihobby.us>

For this guide I had to stick with stable components. While RPi and other arm platforms are great, they are not widely adopted. Making it a hard target to QA. I do know that Rancher (Suse) is making great strides towards Arm all the things. But it will take some time. Since X86-64 SBCs are getting cheap and plentiful, are you able to test on those? Or VMs?

[macooper59]

Yes actually I can test them on the Raspberry Pi 5 and the Orange Pi 5. I will have a beelink mini system with the N100 Processor soon and I am sure it will work on that as well. I will do some testing and send you my results. I can also test in a VM both on Intel/AMD and ARM. Just let me know what you would like me to do.

Absolutely, would love to get feedback!
