  5. Select Private endpoint connections from the top row.
  6. Select + Create.
  7. Select the subscription the Key Vault is within, and other desired configuration.
  8. Select Next.
  9. For resource type select Microsoft.KeyVault/vaults.
  10. Select the Key Vault to associate the Private Endpoint with.
  11. Select Next.
  12. In the Virtual Networking field, select the network to assign the Endpoint.

From Azure CLI​

  1. To create an endpoint, run the following command:
az network private-endpoint create --resource-group <resourceGroup> --vnet-name <vnetName> --subnet <subnetName> --name <PrivateEndpointName> --private-connection-resource-id "/subscriptions/<AZURE SUBSCRIPTION ID>/resourceGroups/<resourceGroup>/providers/Microsoft.KeyVault/vaults/<keyVaultName>" --group-ids vault --connection-name <privateLinkConnectionName> --location <azureRegion> --manual-request
  1. To manually approve the endpoint request, run the following command:
az keyvault private-endpoint-connection approve --resource-group <resourceGroup> --vault-name <keyVaultName> –name <privateLinkName>
  1. Determine the Private Endpoint's IP address to connect the Key Vault to the Private DNS you have previously created.
  2. Look for the property networkInterfaces then id; the value must be placed in the variable privateEndpointNIC within step 7:
az network private-endpoint show -g <resourceGroupName> -n <privateEndpointName>
  1. Look for the property networkInterfaces then id; the value must be placed on privateEndpointNIC in step 7:
az network nic show --ids <privateEndpointName>
  1. Create a Private DNS record within the DNS Zone you created for the Private Endpoint:
az network private-dns record-set a add-record -g <resourcecGroupName> -z "privatelink.vaultcore.azure.net" -n <keyVaultName> -a <privateEndpointNIC>
  1. nslookup the private endpoint to determine if the DNS record is correct:
nslookup <keyVaultName>.vault.azure.net nslookup <keyVaultName>.privatelink.vaultcore.azure.n
