Lab03 - Inspecting State
The Service concept allows you to inspect the health and state of your cluster and the running applications.
You can view the list of all the tasks associated with a service across the cluster. In this case, each task is a container,
docker service ps http
You can view the details and configuration of a service via
docker service inspect --pretty http
On each node, you can ask what tasks it is currently running. Self refers to the manager node Leader:
docker node ps self
Using the ID of a node you can query individual hosts
docker node ps $(docker node ls -q | head -n1)
In the next step, we will scale the service to run more instances of the container.
