These volumes can be attached to just one node, so if you're planning to use multiple replicas for a Service, or to use the same volume in multiple Services, consider using the multi-node attachment.
In Bunnyshell, we called this type Disk.
The benefit of using single-node attachment volumes is their performance advantage over multi-node attachment volumes, which rely on the network to transfer data.
Multi-node attachment (Network)
When in need of a single storage for multiple Services (or replicas of the Same service) to write into, the Network disk type should be used in Bunnyshell.
Behind the scenes, it creates an NFS storage.
Using disk for multiple Services (or replicas of the same Service) is not guaranteed to work, which is why it's not recommended. The Kubernetes Scheduler will probably not schedule Pods based on that condition.
Detecting & Converting volumes
Volumes are automatically detected from your docker-compose.yaml file and the best-performance type is chosen, based on the volume's usage (mount in Services).
Folders mounted locally in docker-compose will not have any use when deployed in Kubernetes (or anywhere else other than a local environment). That is why they are discarded.
At the same time, volumes which are not used in any Component are discarded.
