arm64 support

Affected version

23.1.0

Current and expected behavior

I am trying to follow this guide to install HDFS.

I succeed installing operators by:

helm repo add stackable-stable https://repo.stackable.tech/repository/helm-stable/
helm install --wait zookeeper-operator stackable-stable/zookeeper-operator --version 23.1.0
helm install --wait hdfs-operator stackable-stable/hdfs-operator --version 23.1.0
helm install --wait commons-operator stackable-stable/commons-operator --version 23.1.0
helm install --wait secret-operator stackable-stable/secret-operator --version 23.1.0

Then when I try to install ZooKeeper cluster by:

kubectl apply -f zk.yaml

---
apiVersion: zookeeper.stackable.tech/v1alpha1
kind: ZookeeperCluster
metadata:
  name: simple-zk
spec:
  image:
    productVersion: 3.8.0
    stackableVersion: 23.1.0
  servers:
    roleGroups:
      default:
        replicas: 1

I got error:

Failed to pull image "docker.stackable.tech/stackable/zookeeper:3.8.0-stackable23.1.0": rpc error: code = NotFound desc = failed to pull and unpack image "docker.stackable.tech/stackable/zookeeper:3.8.0-stackable23.1.0": no match for platform in manifest: not found

Any idea, thanks! 😃

It seems docker.stackable.tech/stackable/zookeeper:3.8.0-stackable23.1.0 does not exist.

Environment

➜ kubectl version --short
Flag --short has been deprecated, and will be removed in the future. The --short output will become the default.
Client Version: v1.25.2
Kustomize Version: v4.5.7
Server Version: v1.26.1+k3s1

Hey,

what platform are you running on (try running e.g. "lscpu")?
We currently only support x86_64 images and have experimental support for ARM in some images.

The image docker.stackable.tech/stackable/zookeeper:3.8.0-stackable23.1.0 exists https://repo.stackable.tech/#browse/browse:docker:v2%2Fstackable%2Fzookeeper%2Ftags%2F3.8.0-stackable23.1.0 but i think you "want" to select a platform that is not supported.

Hi @maltesander oh yeah I am running on macOS with M1 CPU.

Luckily, all docket images I have used so far support arm64. Or maybe this is a trend as there are more and more arm64 devices (?)

Is it possible to support arm64? Thanks a lot! 😃

If using GitHub action, simply need https://github.com/docker/setup-qemu-action

      - name: Set up QEMU
        uses: docker/setup-qemu-action@v2
        with:
          platforms: amd64,arm64

Hey @hongbo-miao! Completely agree with you - ARM is taking off. It would be a great dev experience to have it run on an ARM macOS.

Unfortunately, we are not supporting it right now. Mostly due to other priorities taking up most of our attention.

I wouldn't recommend using the platform or running on your ARM machine directly. It may look like QEMU works, but you will have a bad time with very weird crashes instead.

If you can get access to an AMD machine with enough resources, spinning up a temporary remote k8s cluster is the way to go. You can use something like kind - everything will work as expected, and you'll be able to get a good impression of the demos and how the platform works. Sorry for the inconvenience!

Thanks @vsupalov !

FWIW, regarding ARM machine, so far, I had quite good experience. All Docker images in this chart work well in my MacBook Pro with M1 CPU.
Regarding QEMU, I had quite good experience myself too, all images I published work well on my MacBook Pro with M1 CPU too.

It would be great to support in future so that we can test more easily!
I updated the title to more like a "feature request" title. 😃
