You need a copy of the flash drive backup. If you had a copy of the appdata backup, you may have also configured CA to do a flash drive backup to the array. You need to grab a copy of the folder /config/plugins/dockerMan/templates-user from the back up and put it on the flash drive.
If that doesn't exist, then ultimately what you're going to have to do is take a screen shot of the docker tab, with all the ports / paths all showing, then delete the containers and re-add them via Apps and re-enter in the appropriate values. (ie: configure from scratch). You won't lose your appdata though...
