Starting Docker Containers After a Host Restart

I’ve recently started learning Docker, and how to run Docker on a Raspberry PI 3. I soon realized that whenever the host shuts down, or restarts the Docker containers will not restart automatically. I know you can set the container to auto start but if you are a Noob like me, you can use the following to get the containers back up and running. docker ps -a The command docker ps -a will list all the containers event the once that are not running.
