Docker now provides volumedrivers, but the functionality is very limited for now (e.g. Multiple volumes can be mounted to the same instance. This is super helpful, thank you! The traditional way of installing a master and worker nodes in the EC2 instances. Note: Make sure the EBS volume and the instance are in the same zone. With Cloud Volumes ONTAP data tiering, you can create an NFS/CIFS share on Amazon EBS which has back-end storage in Amazon S3. You can attach multiple Multi-Attach enabled volumes to an instance or set of instances. To use a template or YAML file, provide the share details and define the volumes by populating the volumes array in the properties section of the file. To mount an attached EBS volume on every system reboot, add an entry for the device to the /etc/fstab file. Unlike emptyDir, which is erased when a pod is removed, the contents of an EBS volume are persisted and the volume is unmounted.
