Container startup - none.

Hello.
I have a docker and a container with jdownloader-2 installed.
The problem is that after restarting the machine, this container does not start by itself, I have to do it manually with the command:
docker start jdownloader-2
Please tell me what to do to make this container run when deameon docker starts like my other containers. I am asking for a command I should use to fix this.

Regards,
Peter
