I am defining my first Kubernetes deployment and would like to define a container that mounts persistent storage at two points, say like this (in
volumeMounts: - name: volume1 mountPath: /var/log/app - name: volume2 mountPath: /var/lib/app
I understand from Kubernetes' MEAN stack sample that I should be able to create two corresponding GCE disks, say like this:
gcloud compute disks create --size 10GB volume1 gcloud compute disks create --size 10GB volume2
I currently contemplate two disks instead of one only because I need to mount at two different paths. Can a Kubernetes service mount different "portions" (possibly partitions) of a single volume/disk at different paths?
The specification of
v1.VolumeMount suggests that this may not be possible at the level of the service specification, because it supports only the fields
These answers suggests that it might be possible on the level of EXT4 partitions, but that this would require the the volume to be read-only. Even in the read-only case (which does not meet my requirements), how would I go about creating a GCE disk with partitions?
