run "docker run" from crontab

Can't use docker run -it --link [...] when running from cron - I use docker run --link [...] now.

To elaborate on Martin's answer, -it is shorthand for -i -t, ie run interactively on terminal (pseudo TTY), so it's not necessary for running in a cronjob.

If the command is suitable for automation, -it should be not necessary, so removing it should let you run docker from a cron job.
