#### Run some swarm commands to verify the deployment
You can use the swarm command line, as you've done already, to browse and manage
the swarm. Here are some examples that should look familiar by now:
* Use `docker node ls` to list the nodes.
* Use `docker node ls` to list the nodes in your swarm.
```shell
[getstartedlab] ~ $ docker node ls

#### Open ports to services on cloud provider machines
@ -109,10 +99,9 @@ At this point, your app is deployed as a swarm on your cloud provider servers,
as evidenced by the `docker` commands you just ran. But, you still need to
open ports on your cloud servers in order to:
* allow communication between the `redis` service and `web` service on
the worker nodes
* if using many nodes, allow communication between the `redis` service and `web` service
* allow inbound traffic to the `web` service on the worker nodes so that
* allow inbound traffic to the `web` service on any worker nodes so that
Hello World and Visualizer are accessible from a web browser.
* allow inbound SSH traffic on the server that is running the `manager` (this may be already set on your cloud provider)
