Hello world using persistent storage

Prerequisites​

To run this onboarding tutorial, we should first have:

  • a k8saas cluster deployed
info

To ask and set up your own cluster, look at the section Getting Started.

And downloaded the following file:

Tutorial​

The application is a simple ubuntu container with a persistent volume mounted on path /mnt/dst.

Get your credentials​

az aks get-credentials  --name "$K8SAAS_RESOURCE_NAME"  --resource-group "$K8SAAS_RESOURCE_NAME" \
note

The cluster name and the resource group name are the same within k8saas.

Deploy the application​

Deploy the application, composed of :

  • a kubernetes Deployment object: which spin up the application pod (container) and make sure it's up and running at all time;
  • a kubernetes PersistentVolumeClaim object: which bind the mounted path to the kubernetes PersistentVolume object, dynamically created by Azure.
tip

The PersistentVolumeClaim object specify the requested size, and Azure dynamically creates a kubernetes PersistentVolume object and the corresponding Azure Storage Account.

Using the following command:

kubectl apply -f aks-helloworld-pvc.yaml --namespace dev

Remove your test​

kubectl delete -f aks-helloworld-pvc.yaml --namespace dev
