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.

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