Open Standards & Plumbing

Open Container Initiative (OCI)

Coalition of industry leaders join forces to eliminate fragmentation •  Form a vendor-neutral, open source governance model under the Linux

Foundation •  Establish common standards for container format and runtime •  Docker donated its container format, runtime and associated specifications •  Appoint maintainers for the libcontainer project

Before  

•  Inflexible •  Single host •  Limited to one network

X

•  Container SDN •  Distributed networking •  Portable across networks •  Plug ins to broad ecosystem

ABer  

Plugins Pluggable Architecture to extend Docker functionality •  Introducing Networking and Volume plugins •  For Users: Portability and choice for developers and ops •  For Partners: Easily integrate and access Docker users •  Collaboration with Cluster HQ, Glider Labs, Weave

Part Two: Development through to Production •  Build & Run an App in Development

–  Python + MongoDB •  Deploy to a Swarm cluster in Production

–  Scale Web services •  Deploy new MongoDB Cluster in Production

Lets build an App!

Storage: Inside or outside the container?

Inside •  Encapsulation of Concerns

29

Host

daemon

container

Host

daemon

container e.g. SSD

e.g. EBS

Outside •  Separation of concerns •  Storage Features (e.g. snapshots)

/data/db /mnt/xx:/data/db

Summary

• Define  Container,  their  contents  and  how  they  work  together  once  • Deploy  the  same  images  in  Dev,  Pre-­‐Prod  and  Produc-on  across  PlaZorms  

One  solu-on  from  Dev  -­‐>  Produc-on  

• Ops  define  the  whitelisted  images,  security  policies  etc.  • Dev  use  approved  images  to  build  upon  • Eliminate  the  complexity  (and  cost)  of  deployment
