Struggling to configure xibo with docker

I’m have been trying to configure xibo from docker on win7 64, for several days now and I still can’t get it right! I just get the following error message:
Fatal Error - sorry this shouldn’t happen. SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: Name does not resolve

Any suggestion to why I got to this point?

The error you are receiving would suggest there is an issue with your MySQL configuration. As you are running Windows 7, 64 bit I would assume you are following the setup for Docker Toolbox installation Guide.

I would recommend checking the docker yml file you are using for your setup, as well as the config.env file again. You are welcome to send me screenshots of your configuration files so I can take a look. If you would prefer to send these privately, please add them to a private message.

Can you confirm the command you are running prior to receiving this error?

Many Thanks.
