How To Install Jenkins on Kubernetes
What happens to Jenkins volume in scenario where Jenkins pod is redeployed to another worker node? I assume in this example Jenkins volume (Jenkins state/data) persists only on worker node where it was deployed and not across the cluster. So when pod will be redeployed, all state will be lost?

Hi, yes, you are correct. If the pod get redeployed, the volume data would be lost in this case. To make the data persist, you can use a volume backed by something like NFS or a CSI driver. Here is a nice tutorial that talks about using NFS with DOKS: https://www.digitalocean.com/community/tutorials/how-to-set-up-readwritemany-rwx-persistent-volumes-with-nfs-on-digitalocean-kubernetes
