6. Swarm in a nutshell
   • Exposes several Docker Engines as a single virtual Engine
   • Serves the standard Docker API
   • Extremely easy to get started
   • Batteries included but swappable

12. Swarm Scheduler
    2 steps:
    • 1- Apply filters to exclude nodes/offers
    - ports
    - constraints
    - affinity
    - health
    - dependency
    • 2- Use a strategy to pick the best node/offer
    - binpack
    - spread
    - random

13. Resource Management
    • Memory
    $ docker run -m 1g …
    • CPU
    $ docker run -c 1 …
    • Ports
    $ docker run -p 80:80 …

14. Scheduling parameters
    • Constraints
    docker run -e “constraint:node==agent-04” …
    docker run -e “constraint:region==us-east” …
    • (anti-)Affinities
    docker run --name redis-master redis
    docker run --name redis-slave -e “affinity:container!=redis*” …

15. Why Docker Swarm + Mesos?
    Scalable to 10,000s of nodes
    Benefit from Mesos features / APIs
    Mesos + Docker Ecosystem
    Docker client experience
