How to integrate Azure keyvault with ARO cluster ?

Hello Mangi,Balaraju,IN-Chennai,

Thanks for your question.

Please take a look at the guide to use Azure Key Vault Provider for Secrets Store CSI Driver on Azure Red Hat OpenShift

Also, take a look at the Redhat documentation equivalent:

Follow these steps:

• Create a namespace for your application

    oc new-project my-application
  

• Create an Azure Key Vault in your resource group that contains ARO

    az keyvault create -n ${KEYVAULT_NAME} -g ${KEYVAULT_RESOURCE_GROUP} --location ${KEYVAULT_LOCATION} 
  

• Create a secret in the Key Vault

    az keyvault secret set --vault-name ${KEYVAULT_NAME} --name secret1 --value "Hello" 
  

• Create a service principal for the Key Vault

    export SERVICE_PRINCIPAL_CLIENT_SECRET="$(az ad sp create-for-rbac --skip-assignment --name http://$KEYVAULT_NAME --query 'password' -otsv)"
    export SERVICE_PRINCIPAL_CLIENT_ID="$(az ad sp list --display-name http://$KEYVAULT_NAME --query '.appId' -otsv)"
  

• Set an access policy for the service principal

    az keyvault set-policy -n ${KEYVAULT_NAME} --secret-permissions get --spn ${SERVICE_PRINCIPAL_CLIENT_ID} 
  

• Create and label a secret for Kubernetes to access the Key Vault

    oc create secret generic secrets-store-creds -n my-application --from-literal clientid=${SERVICE_PRINCIPAL_CLIENT_ID} --from-literal clientsecret=${SERVICE_PRINCIPAL_CLIENT_SECRET}
    oc -n my-application label secret secrets-store-creds secrets-store.csi.k8s.io/used=true
  

• Install the Secrets Store CSI Driver and Azure Key Vault Provider

helm repo add secrets-store-csi-driver https://kubernetes-sigs.github.io/secrets-store-csi-driver/charts


helm install csi-secrets-store-provider-azure secrets-store-csi-driver/secrets-store-csi-driver --namespace kube-system --set providers.azure.enabled=truehelm repo add secrets-store-csi-driver https://kubernetes-sigs.github.io/secrets-store-csi-driver/charts helm install csi-secrets-store-provider-azure secrets-store-csi-driver/secrets-store-csi-driver --namespace kube-system --set providers.azure.enabled=true

• Create a SecretProviderClass to give access to the Key Vault secre

cat <<EOF | oc apply -f -
apiVersion: secrets-store.csi.x-k8s.io/v1
kind: SecretProviderClass
metadata:
  name: azure-kvname
  namespace: my-application
spec:
  provider: azure
  parameters:
    usePodIdentity: "false"
    useVMManagedIdentity: "false"
    userAssignedIdentityID: ""
    keyvaultName: ${KEYVAULT_NAME}
    objects: |
      array:
        - |
          objectName: secret1
          objectType: secret
EOF
