1. DockerCon16 recap discusses Docker 1.12 release with built-in orchestration features including swarm mode, service API, and built-in routing mesh. 2. The release focuses on developer experience, eliminating friction in the development cycle, and orchestration, introducing the best way to orchestrate Docker which is built into Docker itself. 3. It provides a walkthrough of using the new swarm mode, service API, and other pillars of Docker 1.12, and also discusses opportunities to improve the operations experience through deep integration with platforms like AWS and Azure.

19. Moby - the Docker VM
Alpine was
designed to boot
from init ramdisk
So, restart the
VM should you
run into trouble

20. 3 ways to get to Moby’s console
1. screen ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/tty 9600
2. docker run -it --privileged --pid=host debian nsenter -t 1 -m -u -n -i sh
3. docker run --net host --pid host --privileged -v /:/hostfs chroot /hostfs

22. 2.
Orchestration

23. Introducing the best way to
orchestrate Docker:
Docker.
Docker 1.12: now with orchestration built-in.

24. Swarm mode
Service API
Cryptographic node identity
Built-in routing mesh
Docker 1.12: now with orchestration built-in.

25. Pillars of
Docker 1.12

26. Combine your engines in swarms of any scale
Self-organizing, self-healing
No external data store required
No single points of failure
Infrastructure-agnostic topology
Swarm mode

27. Cryptographic node identity
Government-grade security by default
End-to-end TLS
Built-in government-grade PKI
Automated key rotation
Revoke any node at any time

28. Section 2 - Docker daemon configuration
2.14 Enable live restore
2.15 Set the auto-accept mode for the swarm to none
2.16 Set a secret value when initializing swarm mode
2.17 Do not enable swarm node, if not needed
2.18 Control the number of manager nodes in a swarm
Section 4 - Container Images and Build File
4.6 Add HEALTHCHECK to the container image
Section 5 - Container Runtime
5.26 Check container health at runtime

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

30. Built-in Routing Mesh
Swarm-wide overlay networking
Container-native load-balancing
DNS-based service discovery
No separate cluster to setup
Works with your existing load-balancers
Rock-solid kernel-only data path with IPVS

31. Built-in Routing Mesh
Deep-dive article on Docker 1.12 networking

34. Docker-native experience
No external dependencies
No single point of failure
Secure by default
Works with your infrastructure
Reverse compatible
