I assume this is generally frowned upon, but I would really like to install a docker i can only find on docker  hub (and not CA).

The docker is serposcope and from installing ca dockers and a little guesswork it would seem to be fairly straight forward install.

However, I am running into some difficulties finding out how to configure the docker to see mysql database, username and password (for example). 

Are there any guides for this on the forum?

Any help would be appreciated. 

Thanks

Not really. You are free to try any docker you want.

Nope. Each instance is somewhat unique. It would be best to try to communicate with the docker author if they don't provide proper documentation with the docker.
