Description
In the single-process and multiiprocess links below, the example docker invokations use the "--link" flag, which is being deprecated by docker per [0]

It seems based on docker's notice here that the recommended way to do this now would be either to connect to the database using a network and exposed port, or perhaps sharing mysqld.sock in a volume. Based on the error message I see when I remove the link flag, it appears that huginn is configured to use the socket directly, and might require some changes to connect to the database over the network? I'm not sure. Because of this I spent some time trying to get it to work with docker volumes to share mysqld.sock between the database container and the huginn container, but I haven't made much progress, so any pointers would be appreciated.
