Docker containers can be started, stopped and restarted. When you stop a container, it's not removed but the status is changed to stopped and the process inside of the container is stopped. When you ran the `docker ps` command, the default output is to only show running containers. If you pass the `--all` or `-a` for short, you will see all containers on your system, including stopped containers and running containers.
```console
$ docker ps --all
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

```
If you’ve been following along, you should see several containers listed. These are containers that you started and stopped but haven't removed yet.
Restart the container that you have just stopped. Locate the name of the container and replace the name of the container in the following `restart` command:
```console
$ docker restart inspiring_ishizaka
```
Now, list all the containers again using the `ps` command:
```console
$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d75e61fcad1e docker-gs-ping "/docker-gs-ping" 2 minutes ago Up 5 seconds 0.0.0.0:8080->8080/tcp inspiring_ishizaka
f65dbbb9a548 docker-gs-ping "/docker-gs-ping" 4 minutes ago Exited (2) 2 minutes ago wizardly_joliot
aade1bf3d330 docker-gs-ping "/docker-gs-ping" 4 minutes ago Exited (2) 4 minutes ago magical_carson
52d5ce3c15f0 docker-gs-ping "/docker-gs-ping" 10 minutes ago Exited (2) 4 minutes ago gifted_mestorf
```
Notice that the container you just restarted has been started in detached mode and has port `8080` exposed. Also, note that the status of the container is `Up X seconds`. When you restart a container, it will be started with the same flags or commands that it was originally started with.
