What are some of the use cases where an access mode of "ReadWriteOnce" would be useful for pods? Considering that there will always be more than one instance of a pod on a cluster, when would "ReadWriteOnce" really be useful?
Or am i missing something ?
The RWO is useful for any application that will not be sharing it’s volume with other pods. For instance, if you launch a Jenkins application it does not need to share it’s volume with other Jenkins instances running. Each would want its own volume and it’s own $JENKINS_HOME location. Think of a ReadWriteOnce volume as a local volume/EBS volume rather than a network share/EFS mount.
