| Flocker | https://clusterhq.com/flocker/introduction/ | Seems to be the most popular solution for persistent docker storage; it is unclear if volumes can be read/write accessible on multiple containers. https://flocker-docs.clusterhq.com/en/latest/ has been offline for 2 weeks, so I cannot test it or find out more detailed information. |
| Rook | https://rook.io/ | Built for k8s; based on Ceph; shared file system can be mounted read-write from multiple pods; not production ready until 12/2017 (https://github.com/rook/rook/blob/master/ROADMAP.md) |
| REX-Ray | https://rexray.readthedocs.io | Not sure of the maturity of the project; Couldn't find any numerated list of features or any websites describing their experience with it; Developed by DELL/EMC. |
| Infinit | https://infinit.sh | Still in alpha stages; details limited |

AWS
Using Amazon EFS to Persist Data from Amazon ECS Containers
Docker for AWS persistent data volumes

Azure
