Datashim: Streamlined S3 and NFS Dataset Management for Kubernetes

Overview

Datashim is a Kubernetes Framework to provide easy access to S3 and NFS Datasets within pods. It orchestrates the provisioning of Persistent Volume Claims and ConfigMaps needed for each Dataset.

Using manifests

If you prefer, you can install Datashim using the manifests provided. Start by creating the dlf namespace with:
Start by creating the dlf namespace with:

create ns

kubectl create ns dlf
Enter fullscreen mode Exit fullscreen mode

In order to quickly deploy Datashim

kubectl apply -f https://raw.githubusercontent.com/datashim-io/datashim/master/release-tools/manifests/dlf.yaml

kubectl label namespace default monitor-pods-datasets=enabl
Enter fullscreen mode Exit fullscreen mode

Post-install steps

Ensure that Datashim has been deployed correctly and ready by using the following command:

kubectl wait --for=condition=ready pods -l app.kubernetes.io/name=datashim -n dlf
Enter fullscreen mode Exit fullscreen mode

To use Datashim, we need to create a Dataset: we can do so by editing and running the following:

apiVersion: datashim.io/v1alpha1
kind: Dataset
metadata:
    name: example-dataset
spec:
   local:
     type: COS
     accessKeyID:  test@1234
     secretAccessKey: test@1234
     endpoint: https://minio.demo.com
     bucket: demo
     region: us-east-1 
Enter fullscreen mode Exit fullscreen mode

If everything worked, you should now see a PVC named example-dataset which you can mount in your pods. Assuming you have labeled your namespace with monitor-pods-datasets=enabled as mentioned in the post-install steps, you will now be able to mount the PVC in a pod as simply as this:

apiVersion: v1
kind: Pod
metadata:
    name: nginx
spec:
    volumes:
    - name: "example-dataset"
      persistentVolumeClaim:
        claimName: "example-dataset"
    containers:
    - name: nginx
      image: nginx
      volumeMounts:
        - mountPath: "/mount/dataset1" 
          name: "example-dataset"
Enter fullscreen mode Exit fullscreen mode
