how to maintain encryption/decryption of Kubernetes Secrets in AKS. I referred this link https://kubernetes.io/docs/tasks/administer-cluster/encrypt-data/ but as per this link https://feedback.azure.com/d365community/idea/ec780bf4-f724-ec11-b6e6-000d3a4f0da0 I am not sure whether this feature is available in Azure Kubernetes Service (AKS).
consider managing the secrets in azure key vault. Integrate AKS cluster with azure key vault to source the secrets when the pod is started.
Following link would be helpful --> https://medium.com/swlh/integrate-azure-key-vault-with-azure-kubernetes-service-1a8740429bea

I'm about to create a new Azure AKS cluster and I want to integrate AKS with Azure Key Vault.
A few months ago, during the study phase, I saw that it was necessary to use Azure AD pod-managed identities to do this, but now I found that this will be replaced by Azure AD workload identity
At this point, I'm a bit confused because the first one will be replaced, but the second one is not ready for production.
Any suggestions?
ATM Azure AD pod identities is the way to go. Azure workload identity will replace AAD Pod identity as you already mentioned bcs they will solve some limitations as you can read here. I think there will be a documentation how to migrate from AAD pod identity to Azure Workload identityas soon when they want GA.
You could also use the Azure Key Vault Provider for Secrets Store CSI Driver to integrate Azure Key Vault with your AKS.
I am working with terraform to spin up different resource in azure. Some of those resources have sensitive data that I would like to store securely in aws secret manager.
Is this a doable process in terraform?
What it is confusing me is the following question:
To be able to access aws secret manager and spin up azure resources, should I have both provider declared in my terraform?
thank you very much for any advice and clarification you can offer
To be able to access aws secret manager and spin up azure resources,
should I have both provider declared in my terraform?
Of course, yes. You need to configure Azure provider and AWS provider for each one.
And I agree with Matt, if the resources have sensitive data, you can use the Azure Key Vault. then you can use only one provider and it will spend less time to get them.
I have an Asp.Net Core application that is configured to connect to Azure KeyVault using Visual Studio 2019 Connected Services:
https://learn.microsoft.com/en-us/azure/key-vault/general/vs-key-vault-add-connected-service
I containerized the application with Docker and deployed it into Kubernetes as a Pod.
The KeyVault connection is not working, probably because of the Managed Identity not set-up.
I tried:
Added the Kubernetes agent Managed Identity to the KeyVault Acccess policies like I would do with App Services or Container Services, but does not allow the connection.
Followed the docs here: https://learn.microsoft.com/en-us/azure/key-vault/general/key-vault-integrate-kubernetes
I wonder if the "Azure Key Vault provider for the Secrets Store CSI driver on Kubernetes" is the right way to use KeyVault from a pod, or if there is a simpler solution like a direct connection.
The solution, for whoever is in my situation, is to use AAD-Pod Identity
There is no need to attach a CSI Driver unless you need the Secrets in the Kubernetes configuration, want total control on custom configurations, or have the cluster outside Azure.
For Asp.Net Core applications deployed to AKS, the easiest way is to use Managed Identities, and to provide that to your Kubernetes Cluster you need AAD-Pod identity.
There is not a documentation page yet, but following the Get Started instructions on GitHub is enough to get it going.
I managed to get a secret from the Azure key vault in my pod, using Managed Identity. Just add the .identityProfile.kubeletidentity.clientId of the AKS cluster as a Key Vault policy to read the secrets. You must set this policy through the Azure Portal, because the "az keyvault set-policy" expects the --object-id to be a principalId i guess...
We have some dotnet Core App Services running on Azure and using Azure key Vault with Managed Identities.
Planning to deploy these dotnet core services to azure kubernetes but I haven't found any relevant document/support to use AKV with Kubernetes Services. Any Guidance or references
There are a couple of options to access KV from AKS:
Use Azure Key Vault with FlexVol (deprecated. continue to use this for kubernetes version 1.15)
With Key Vault, you store and regularly rotate secrets such as credentials, storage account keys, or certificates. You can integrate Azure Key Vault with an AKS cluster using a FlexVolume. The FlexVolume driver lets the AKS cluster natively retrieve credentials from Key Vault and securely provide them only to the requesting pod. Work with your cluster operator to deploy the Key Vault FlexVol driver onto the AKS nodes. You can use a pod managed identity to request access to Key Vault and retrieve the credentials you need through the FlexVolume driver.
Azure Key Vault with FlexVol is intended for use with applications and services running on Linux pods and nodes.
Use Azure Key Vault Provider for Secrets Store CSI Driver (For kubernetes 1.16+)
The Azure Key Vault Provider for Secrets Store CSI Driver allows for the integration of Azure Key Vault as a secrets store with a Kubernetes cluster via a CSI volume.
Use Azure Active Directory pod-managed identities in Azure Kubernetes Service (Preview)
Azure Active Directory (Azure AD) pod-managed identities use Kubernetes primitives to associate managed identities for Azure resources and identities in Azure AD with pods. Administrators create identities and bindings as Kubernetes primitives that allow pods to access Azure resources that rely on Azure AD as an identity provider.
I found the pod identity approach easier as you don't need to change your code.
I am working with Kubernetes on Azure. I created and configured the Azure Kubernetes Service and Azure Container Registry with the Azure command line interface (CLI) - I have a repository full of Azure CLI bash scripts that create/destroy my cloud infrastructure.
I plan to deploy to Kubernetes using Helm. I plan to use Helm Secrets to encrypt secrets and I am hoping I can use Azure Key Vault to store the encryption keys that encrypt/decrypt the "secrets".
I am now trying to create and configure the Azure Key Vault to work with Azure Kubernetes Service. I can see how I could create a Key Vault with the Azure CLI but the documentation for kubernetes-kms suggests that if you configure Kubernetes a certain way then the Key Vault will be automatically created and this will be configured to communicate with Azure Kubernetes Service.
"We have added this feature to aks-engine so that you do not have to
worry about any of the manual steps to set this up."
The documentation talks about editing a "kubernetesConfig", I've not seen a "kubernetesConfig" anywhere yet - I guess that is what you would have if you created your components using Azure Resource Manager (ARM) Templates.
How do I get Azure Key Vault working with kubernetes-kms using Azure CLI?
e.g. adding enableEncryptionWithExternalKms to the Kubernetes configuration and adding an objectId attribute to the service principal.
you cannot do that with AKS. You dont have access to masters to configure them.
