Cloud providers like Google, Amazon, and Microsoft typically have a limit on how many volumes can be attached to a Node. It is important for Kubernetes to respect those limits. Otherwise, Pods scheduled on a Node could get stuck waiting for volumes to attach.
1- Kubernetes default limits:
The Kubernetes scheduler has default limits on the number of volumes that can be attached to a Node:
| Cloud service | Maximum volumes per Node |
|---|---|
| Amazon Elastic Block Store (EBS) | 39 |
| Google Persistent Disk | 16 |
| Microsoft Azure Disk Storage | 16 |
2- Custom limits
3- Dynamic volume limits
