Velero POD deployment is getting crashed in AKS

Question

Velero to Backup AKS cluster

We have deployed Velero in our kube cluster engine which is running in Azure stack environment. The Velero platform we installed : "velero-v1.4.2-linux-amd64". Later using the command velero install we deployed kube deployment which is getting crashed regularly.

We need Velero should be up & running and further we should take backup of the K8 cluster. Used below command to deploy velero in kube cluster.

velero install --provider azure --plugins velero/velero-plugin-for-microsoft-azure:v1.0.1 --bucket dxccnastorage --secret-file ./credentials-velero --backup-location-config resourceGroup="StorageRG",storageAccount="dxccnastorage0312" --snapshot-location-config resourceGroup="StorageRG"

Environment Used:

velero version
Client:
Version: v1.4.2
Git commit: 56a08a4

kubectl version --short
Client Version: v1.14.8
Server Version: v1.14.8

OS Release
NAME="Ubuntu"
VERSION="16.04.6 LTS (Xenial Xerus)"

ID_LIKE=debian
PRETTY_NAME="Ubuntu 16.04.6 LTS"

@Boopathy, Elango Firstly, apologies for the delay in responding on this and any inconvenience this issue may have caused.

Mostly usually this indicates something in the credentials file is invalid - could you double-check all the values there?

Moreover something similar is reported on this GitHub thread and can be helpful to you.

You can refer to this article as well if already not to check pre-requisite and all the permissions needed.

Hope it helps!!!
