Question: on Volume

[hardcoar]

Hi! im new to k8s. I was wondering, where are all data stored? i mean, pods may die anytime right? hence the replication. I'm more concerned where is the data residing? i mean does it use disk ssd or in ram? I don't have any idea where to find it. Do i have to create a store or something? I already have a cluster running and I also put some data in it. I still haven't figure it out yet. Cheers!

btw i followed this https://github.com/kubernetes/kubernetes/tree/release-1.3/examples/mysql-galera

im planning to use it in gke. i'm curious. do i need to set up a storage for this? if not where does it reside? thanks in advance

If you want persistant storage, you can attach volumes to your pod. Otherwise, the data will lose after the pods are killed.
