Hello , i'm able to upgrade eleasticsearch from v 6.6.0 to 7.1.1 using the officially provided docker in a stetefull set in kubernetes without a problem. After applying the cluster.initial\_master\_nodes with a list of 3 hosts the master is elected and everything works fine. After i redeploy the same version the pods are recreated and they complain about being part of the previous cluster ( referencing the old cluster\_uuid ) and that they cannot form a new cluster .
The setup is: 3 pods / nodes acting as masters + 2 data nodes
My questions are the following :
1. I would like to avoid storing the /data folder from the master nodes ( pods ) on a persistent volume, so is it possible to inject the same cluster\_uuid into the configuration when recreating the masters , or maybe i'll need to pass more metadata ?
2. Since version 7 i can see that there are a lot of changes in cluster formation. Can you share what are the best practices in using the kubernetes environment and keeping stuff agile and stable at the same time ?
Thank you !

It is essential that the master nodes have persistent storage. From [the docs](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html#master-node):
> Master nodes must have access to the `data/` directory (just like `data` nodes) as this is where the cluster state is persisted between node restarts.

Thanks David for your quick reply, i'll change the config and try to keep the data folder.
