# 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 tasks 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 tasks ` to see the updated task list: ``` $ docker service tasks helloworld ID NAME SERVICE IMAGE LAST STATE DESIRED STATE NODE 8p1vev3fq5zm0mi8g0as41w35 helloworld.1 helloworld alpine Running 7 minutes Running worker2 c7a7tcdq5s0uk3qr88mf8xco6 helloworld.2 helloworld alpine Running 24 seconds Running worker1 6crl09vdcalvtfehfh69ogfb1 helloworld.3 helloworld alpine Running 24 seconds Running worker1 auky6trawmdlcne8ad8phb0f1 helloworld.4 helloworld alpine Running 24 seconds Accepted manager1 ba19kca06l18zujfwxyc5lkyn helloworld.5 helloworld alpine Running 24 seconds Running worker2 ``` 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).
