If it is logs that you are looking to write to disk, I suggest you look at logspout https://github.com/gliderlabs/logspout. This will collect each pod's logging and then you can use google cloud platforms' fairly new logging service that uses fluentd. That way all logs from each pod are collected into a single place.

If it is data that would normally write to a database or something of that nature, I recommend having a separate server outside of the kubernetes cluster that runs the database.

EDIT

For sharing files amongst pods, I recommend mounting a google cloud storage drive to each node in your kubernetes cluster, then setting that up as a volume into each pod that mounts to that mounted directory on the node and not directly to the drive. Having it mount to each node is good because pods do not run on designated nodes, so it's best to centralize it in that case.
