I have an use-case where I would like to mount Google Cloud Storage (GCS) bucket (and a directory in that bucket) in my container and use it as a regular FS. Currently, it seems doable using s3fs-fuse (https://github.com/s3fs-fuse/s3fs-fuse) - thanks @brendanburns. It would be great if GCS was supported as a first class Volume in Kubernetes.
