This summarizes the key points from DockerCon 2016 based on a presentation by Philipp Garbe: 1. Docker 1.12 introduced built-in orchestration capabilities including swarm mode, routing mesh, and a new service API for desired state reconciliation and scheduling. 2. Demos showed deploying an app using the new service command, scaling the app, performing rolling updates, and rescheduling tasks after node failures. 3. Other announcements included Docker for Mac/Windows public betas, Docker Store for publishing content, and Docker DataCenter for deploying applications to AWS and Azure.

10. Docker 1.12: Built-in Routing Mesh
● Swarm-wide overlay networking
● Container-native load-balancing
● DNS-based service discovery
● Works with your existing load-balancers
● Rock-solid kernel-only data path with IPVS

11. ● Desired state reconciliation
● Scaling
● Rolling updates
● Advanced scheduling
● Application-specified health checks
● Rescheduling on node failure
Docker 1.12: Service API

12. 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

13. DEMO

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

15. "Nobody cares about containers. It’s the
application that matters!”
