Subject Re: Kafka Deplopyment Using Kubernetes (on Cloud) - settings for log.dirs
Date Mon, 22 Oct 2018 17:06:51 GMT
Thanks a lot for your prompt answer. This is what I was expecting.

So, if we had three pods where volumes are mapped as the following

Pod 1 = (log.dirs=/some/directory1)
Pod 2 = (log.dirs=/some/directory2)
Pod 3 = (log.dirs=/some/directory3)

if something bad happens to Pod 3 and goes down, would we be able to spin
up a new pod with the same logs.dir location?

Sorry if I am thinking of something impossible, but kafka and zk are
essentially databases and has some stateful items. So just trying to
understand how it all becomes different when deployed with K8s on public
cloud.

Thanks,
