18. Docker for Mac & Windows Public Beta
docker.com/getdocker

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
coming...

32. A walk-through

33. Swarm mode

Cryptographic node identity
Built-in routing mesh
Docker 1.12: now with orchestration built-in.

34. Docker-native experience
No external dependencies
No single point of failure
Secure by default
Works with your infrastructure
Reverse compatible
Docker 1.12: now with orchestration built-in.

35. A walk-through

36. Using the beta? You already have 1.12
installed.
> docker swarm init
> docker service create

37. 3.
Ops experience

38. beta.docker.com
Docker for AWS Docker for Azure

39. Deep integration with native load-balancers, templates,
SSH keys, ACLs, scaling groups, firewall rules…

40. It’s the application that matters!
Nobody cares about containers

41. Distributed Application Bundle
experimental
www.docker.com/dab
A portable format for multi-container applications

43. Thank you!
