Open extensible platform

• Customers want choice

• Consistent Docker UX - “one platform”

• We are launching plugins to enable this

Docker platform

Data volumes Networking

Composition Scheduling

Open collaboration

It’s this simple

$ docker run --publish-service=service.network.weave your_networked_container

$ docker run -v volume_name:/data --volume-driver=flocker your_stateful_container

The problem

• Every customer is unique

• Customers want freedom to choose

• Users can’t use tools together

The solution

• Docker plugins are the solution. Batteries included but swappable

• Today: Networking, Data Volumes

• Future: Logging, Swarm schedulers

• You decide for your app, different choices in different environments

What is a plugin?

• Chunk of new functionality for Docker

• Runs anywhere that Docker runs

• You install the plugin

• Access functionality via regular Docker interface

• Enables cool new features

Demo!

• Flocker and Weave loaded as plugins

• Using Docker Swarm and Docker Compose

• Moving container with data and network identity

What just happened?

• Use case: need to upgrade my servers

• Portability of stateful containers with network identity is an enterprise readiness issue

• This demo just showed how Docker plugins make it possible while keeping Docker’s brilliantly simple UX
