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 Deployment.yaml
inside spec.template.spec.containers.-
):
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 name
, readOnly
, and mountPath
.
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?
