A task is the atomic unit of scheduling within a swarm. When you declare a
desired service state by creating or updating a service, the orchestrator
realizes the desired state by scheduling tasks. For instance, you define a
service that instructs the orchestrator to keep three instances of a HTTP
service that instructs the orchestrator to keep three instances of an HTTP
listener running at all times. The orchestrator responds by creating three
tasks. Each task is a slot that the scheduler fills by spawning a container. The
container is the instantiation of the task. If a HTTP listener task subsequently
container is the instantiation of the task. If an HTTP listener task subsequently
fails its health check or crashes, the orchestrator creates a new replica task
that spawns a new container.
