Can contents of Keytab file be stored and used from Azure Key vault?

768 Views Asked by At

I have a keytab file used for authentication when trying to connect from Azure Kubernetes Cluster to On-prem hadoop nodes.

Can I store keytab contents in Azure Key vault and read it back?

Technically, you should be able to. It's not implemented out of the box but you could shoe horn it in. You'd have translate back and forth to unicode using the keytab as a secret. You'd still need to create it as a file, and that reverts back to protecting it by permission, and then cleaning it up after your done. So out of the box it's likely possible but there's a lot of extra manual management.
