<p>EDIT:
It was a config error, I was setting wrong kv name :/</p>
<p>As said in title I'm facing an issue with secret creation using SecretProviderClass.</p>
<p>I've created my aks and my kv (and filled it) on azure. then I'll proceed to follow <a href="https://learn.microsoft.com/en-us/azure/aks/csi-secrets-store-driver" rel="nofollow noreferrer">those</a> steps using a user-assigned managed identity</p>
<p>but no <code>secret</code> resource get created and pods got stuck on creation with mount failure.</p>
<p>those are the steps I followed</p>
<pre><code>az extension add --name aks-preview
az extension update --name aks-preview
az aks enable-addons --addons azure-keyvault-secrets-provider -g $RESOURCE_GROUP -n $AKS_CLUSTER 
az aks update -g $RESOURCE_GROUP -n $AKS_CLUSTER --enable-managed-identity --disable-secret-rotation
$AKS_ID = (az aks show -g $RESOURCE_GROUP -n $AKS_CLUSTER --query identityProfile.kubeletidentity.clientId -o tsv)
az keyvault set-policy -n $AZUREKEYVAULT --secret-permissions get --spn $AKS_ID
</code></pre>
<p>the SecretProviderClass manifest I'm using</p>

<p>I'm sure I'm missing something, but can't understand what.
Thanks in advance!</p>

<p>you are using the clientId, but it should be the objectId form the kubelet identity:</p>
<pre><code>export KUBE_ID=$(az aks show -g &lt;resource group&gt; -n &lt;aks cluster name&gt; --query identityProfile.kubeletidentity.objectId -o tsv)
export AKV_ID=$(az keyvault show -g &lt;resource group&gt; -n &lt;akv name&gt; --query id -o tsv)
az role assignment create --assignee $KUBE_ID --role &quot;Key Vault Secrets Officer&quot; --scope $AKV_ID
</code></pre>
<p>This is a working SecretProviderClass i am using (adjusted to your config):</p>

<p>You can also check documentation <a href="https://azure.github.io/secrets-store-csi-driver-provider-azure/configurations/sync-with-k8s-secrets/" rel="nofollow noreferrer">here</a> as you will find better examples as on the Azure Docs.</p>
