[Question] Shared storage between windows and linux node on single cluster deployment #104

Closed dsfrederic closed 1 year ago

dsfrederic commented 1 year ago

Describe scenario I need to access the same data first on the windows node. Then I would like to do some transformations with a pod that's located on the Linux node. Afterwards the windows node takes that data and sends it to a storage account in Azure.

Question What would be the best method to do this?

First attempts

  1. Local path -> Doesn't make sense since the local path on windows node will not have the same data as the one in linux node.
  2. NFS on windows host -> Seems to not be accessible from within the cluster

Hi @dsfrederic,

Thanks for reaching out. A couple of thoughts on your scenario

1) Local path is not an option because of the reason you mentioned. Also, currently, we do not support local path storage on the Windows node.

2) NFS on a Windows host could be an option, but currently, we do not support NFS storage binding on the Windows node. You could implement an NFS connection directly on the container, although it's something we do not recommend

3) Use communication between pods, something like MQTT or Kafka. You could also use a KV store but will depend on the size of your files

4) We plan to bring support for file/folder sharing in the future, similar to Share a Windows folder with Azure IoT Edge for Linux on Windows. Would this be something you are looking forward?

Thanks, Francisco

@fcabrera23 This would be immensely helpful. Is this something we can test in beta?

I've changed my design a little bit so that I don't have to use the windows node. The same issue still arises. I need to access the same files from my HOST OS and within a Kubernetes container. What is the best method to do this?

@fcabrera23 please reopen.

Hi @dsfrederic,

Thanks for reaching out. I think the question was answered. If you want, you can open a new issue as a feature request for file sharing between the host OS and the Linux node.

Thanks, Francisco
