[6.8.0] docker --link kills container => command failed

Im losing one container after another on auto updates.

I just found out about it today.

/usr/bin/docker: links are only supported for user-defined networks.
See '/usr/bin/docker run --help'.

The command failed.

I don't want to generate a network for  a mysql machine where all the container accessing this machine are in the same network and also do not really like the cli way of adding custom networks.

This is why i liked the linking.

Is there another way or do i miss something?
Going back to 6.7.2 for now and will report back if this is only a 6.8.0 issue
