ECK managed cluster and elasticsearch-node

Hi everyone!

Is there a way to use elasticsearch-node tool in ECK managed pods?
To be more exact, kubectl get elasticsearch returns 'unknown' state due to a loss of all masters at the same time, and although master pods are back up, they refuse to join the cluster. There are several data only nodes and we were thinking of repurpose one of them to act as master to try as one of our recovery options. We might be way off so any suggestion is welcomed.


You can see some previous discussion on a similar topic here. Though it makes me wonder if you are not using persistent volumes for the masters as the cluster should be able to recover even if all masters are shut down. But if the masters lost their data then this would be expected.
