ARM64 architecture support for RPi testing

[TerryHowe]

The images definitely work on Raspberry Pi 4 model B running 64 bit Buster:

root@rpi-159:~# uname -a
Linux rpi-159 5.4.79-v8+ #1373 SMP PREEMPT Mon Nov 23 13:32:41 GMT 2020 aarch64 GNU/Linux
root@rpi-159:~# cat /etc/os-release 
PRETTY_NAME="Debian GNU/Linux 10 (buster)"
NAME="Debian GNU/Linux"
VERSION_ID="10"

VERSION_CODENAME=buster
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

I have some etcd config problems, so not a running cluster at this point.

I haven't tried arm64, but it should work https://gallery.ecr.aws/eks-distro/kubernetes/kube-apiserver for example notice it shows arm64

@paavan98pm to get the EKS snap on ARM64 currently you will to build it on an ARM^$ machine with:

sudo snap install snapcraft --classic
git clone https://github.com/canonical/eks-snap.git
cd eks-snap
snapcraft

From a quick test I did, all seemed to work apart from the storage integration with AWS.

As @TerryHowe mentioned, arm64 builds are available for the EKS-D binaries/container images. @ktsakalozos might be able to confirm if the eks snap supports arm64 or not?

[ktsakalozos]

At this point the EKS snap is for AMD64 only, ARM support should come soon.

Thanks @ktsakalozos. Is there a way to switch API server in Microk8s to use the EKS-D API server from the aforementioned ECR public image?

[paavan98pm]

@ktsakalozos Both, R-Pi and c6g.metal returned the error below when running snapcraft:

launch failed: Internal error: qemu-system-x86_64 failed getting vmstate (Process returned exit code: 1) with output:
qemu-system-aarch64: -nographic: No machine specified, and there is no default
Use -machine help to list supported machines

[ktsakalozos]

@paavan98pm if qemu is not available you can build the snap in an lxd container. Instead of snapcraft call snapcraft --use-lxd.

To get lxd you can do:

sudo apt-get remove lxc*
sudo apt-get remove lxd*
sudo snap install lxd
lxd init --auto

[TerryHowe]

I think we have completed everything to support ARM for EKS-D although there may be additional work in the eks snap repository, but that can be worked on over there.
