# Scale the service in the swarm Once you have [deployed a service](deploy-service.md) to a swarm, you are ready to use the Docker CLI to scale the number of service ps in the swarm. 1. If you haven't already, open a terminal and ssh into the machine where you run your manager node. For example, the tutorial uses a machine named `manager1`. 2. Run the following command to change the desired state of the service running in the swarm: ```bash $ docker service scale = ``` For example: ```bash $ docker service scale helloworld=5 helloworld scaled to 5 ``` 3. Run `docker service ps ` to see the updated task list: ``` $ docker service ps helloworld NAME IMAGE NODE DESIRED STATE CURRENT STATE helloworld.1.8p1vev3fq5zm0mi8g0as41w35 alpine worker2 Running Running 7 minutes helloworld.2.c7a7tcdq5s0uk3qr88mf8xco6 alpine worker1 Running Running 24 seconds helloworld.3.6crl09vdcalvtfehfh69ogfb1 alpine worker1 Running Running 24 seconds helloworld.4.auky6trawmdlcne8ad8phb0f1 alpine manager1 Running Running 24 seconds helloworld.5.ba19kca06l18zujfwxyc5lkyn alpine worker2 Running Running 24 seconds ``` You can see that swarm has created 4 new tasks to scale to a total of 5 running instances of Alpine Linux. The tasks are distributed between the three nodes of the swarm. One is running on `manager1`. 4. Run `docker ps` to see the containers running on the node where you're connected. The following example shows the tasks running on `manager1`: ``` $ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 528d68040f95 alpine:latest "ping docker.com" About a minute ago Up About a minute helloworld.4.auky6trawmdlcne8ad8phb0f1 ``` If you want to see the containers running on other nodes, you can ssh into those nodes and run the `docker ps` command. ## What's next? At this point in the tutorial, you're finished with the `helloworld` service. The next step shows how to [delete the service](delete-service.md).
