### Viewing the container's pids
And you can observe the httpd pid in the container with *top*.
```
# sudo podman top <container_id>

### Stopping the container
To stop the httpd container:
```
# sudo podman stop --latest
$ sudo podman stop --latest
```
You can also check the status of one or more containers using the *ps* subcommand. In this case, we should
use the *-a* argument to list all containers.
```
# sudo podman ps -a
$ sudo podman ps -a
```
### Removing the container
To remove the httpd container:
```
# sudo podman rm --latest
$ sudo podman rm --latest
```
You can verify the deletion of the container by running *podman ps -a*.
