How can I achieve real-time synchronization of flow when the application is running in two dockers?  
I want to store the active flow into a database.

Storing flows in a database will require a Storage Plugin, the API that the plugin needs to implement can be found here: [Storage API : Node-RED](https://nodered.org/docs/api/storage/)

An example MongoDB backed plugin can be found here: [GitHub - hardillb/node-red-contrib-storage-mongodb: A flow/library storage plugin for Node-RED that uses MongoDB as the backend](https://github.com/hardillb/node-red-contrib-storage-mongodb)

As for keeping 2 Node-RED instances in step, then you would need to extend any storage plugin to use the Admin API to trigger a flow reload on the other instance when ever a deploy is triggered. Details of the Admin API are here: [Admin API : Node-RED](https://nodered.org/docs/api/admin/)
