● Desired state reconciliation

● Scaling

● Rolling updates

● Advanced scheduling

● Application-specified health checks

● Rescheduling on node failure

Docker 1.12: Service API

Docker 1.12: Service Deployment

Declare

ScheduleReconcile

$ docker service create declares the service name, network, image:tag port, and scale

Managers break down service into tasks, schedules them and workers execute tasks

Engines check to see what is running and compared to what was declared to “true up” the environment

DEMO

Demo● Create a Swarm cluster (1 Manager, 2 Workers)● Deploy an app (using Service command)● Scale-up● Rolling update● Kill “container”● Kill “worker”
