Database Docker persistence Framework based on Swarm and Ceph

The swarm cluster has two main limitations: 1) the data of database container will lost after the container goes down; 2) the lack of migration ability of database container across the hosts. To tackle these issues, we propose a novel persistence framework in both single database and database cluster. To be specific, we use ceph to provide migrable data volumes, and use two frameworks to migrate container from the perspective of container downtime recovery. By comparing the processing time of downtime database container, the experimental results demonstrate that our proposed method is able to shorten the recovery time of database container and improve the availability of database services.
