# Inspect a service on the Swarm When you have [deployed a service](deploy-service.md) to your Swarm, you can use the Docker CLI to see details about the service running 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 `docker service inspect --pretty ` to display the details about a service in an easily readable format. To see the details on the `helloworld` service: ``` $ docker service inspect --pretty helloworld ID: 2zs4helqu64f3k3iuwywbk49w Name: helloworld Mode: REPLICATED Scale: 1 Placement: Strategy: SPREAD UpdateConfig: Parallelism: 1 ContainerSpec: Image: alpine Command: ping docker.com ``` >**Tip**: To return the service details in json format, run the same command without the `--pretty` flag. ``` $ docker service inspect helloworld [ { "ID": "2zs4helqu64f3k3iuwywbk49w", "Version": { "Index": 16264 }, "CreatedAt": "2016-06-06T17:41:11.509146705Z", "UpdatedAt": "2016-06-06T17:41:11.510426385Z", "Spec": { "Name": "helloworld", "ContainerSpec": { "Image": "alpine", "Command": [ "ping", "docker.com" ], "Resources": { "Limits": {}, "Reservations": {} } }, "Mode": { "Replicated": { "Instances": 1 } }, "RestartPolicy": {}, "Placement": {}, "UpdateConfig": { "Parallelism": 1 }, "EndpointSpec": {} }, "Endpoint": { "Spec": {} } } ] ``` 4. Run `docker service tasks ` to see which nodes are running the service: ``` $ docker service tasks helloworld ID NAME SERVICE IMAGE DESIRED STATE LAST STATE NODE 1n6wif51j0w840udalgw6hphg helloworld.1 helloworld alpine RUNNING RUNNING 19 minutes manager1 ``` In this case, the one instance of the `helloworld` service is running on the `manager1` node. Manager nodes in a Swarm can execute tasks just like worker nodes. Swarm also shows you the `DESIRED STATE` and `LAST STATE` of the service task so you can see if tasks are running according to the service definition. 4. Run `docker ps` on the node where the instance of the service is running to see the service container. >**Tip**: If `helloworld` is running on a node other than your manager node, you must ssh to that node. ```bash $docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES a0b6c02868ca alpine:latest "ping docker.com" 12 minutes ago Up 12 minutes helloworld.1.1n6wif51j0w840udalgw6hphg ``` ## What's next? Next, you can [change the scale](scale-service.md) for the service running in the Swarm.
