Vault helm chart share backend between multiple kubernetes clusters

[fbongiovanni29]

Is it possible to share a backend between multiple kubernetes clusters to utilize the vault injected secrets?

This is desirable so that we can have centralized secrets & UI

Can we have one Hashicorp vault backend for multiple kubernetes clusters ( of different vendors like openshift, racnher etc )

You can remount the kub auth engine multiple times (at a resource cost) it isn’t exactly best practice, but if you need multiple clusters than that’s the answer.

Thanks for response, So having one vault server ( in HA mode ) for multiple k8s clusters is not best practice ?

remounting the same engine multiple times just to “separate” them is not best practice.
