${IMAGE_NAME} Restore Tool
(c) 2022 Dave Conroy (https://github.com/tiredofit)

This script will assist you in recovering databases taken by the Docker image.
You will be presented with a series of menus allowing you to choose:
   - What file to restore
   - What type of DB Backup
   - What Host to restore to
   - What Database Name to restore to
   - What Database User to use
   - What Database Password to use
   - What Database Port to use

The image will try to do autodetection based on the filename for the type, hostname, and database name.
The image will also allow you to use environment variables or Docker secrets used to backup the images

The script can also be executed skipping the interactive mode by using the following syntax/

    $(basename "$0") <filename> <db_type> <db_hostname> <db_name> <db_user> <db_pass> <db_port>

If you only enter some of the arguments you will be prompted to fill them in.
