1.OPEN SOURCE

“You can’t out-innovate the world...

- Dr. Angel Luis Diaz Vice President, IBM Cloud Technology & Architecture

Linux Foundation Collaboration

projects have generated 115 million

lines of code .. valued at $5 billion

USD..- Sep 30, 2015 Linux Foundation report

The core docker engine GitHub project has over 25,900 stars and almost 7000 forks, with > 1000 actual contributors

- https://github.com/docker/docker

The OpenStack Foundation has 28,000 individual members worldwide with > 100 corporate

sponsors employing 1000s of contributors

2.DOCKER CONTAINERS

engine

What is Docker?

REST API

Shared Linux kernel

Client/end user

DockerHub

Isolation relies on core Linux kernel technologies:cgroups, namespaces, capabilities, LSM restrictions, etc.

Build, ship and run distributed applications via a common toolbox...

Docker is now a fast-growing ecosystem of related projects:• Compose• Swarm• Machine• Advanced networking• Registry (DTR)• Kubernetes/Mesos• ..among many others$ docker run redis

$ docker run nginx$ docker run ..

Practical Docker

Docker container image• A filesystem (set of independent &

shareable layers)• A configuration (what to run & how)• Pushable to a remote repository for

sharing with others (taggable and versionable)

TINY CONTAINERSHow small can you go?

IBM Contributions to Docker• 1 upstream contributor in August 2015; now 25• IBM has 2 core engine maintainers • IBM has contributions across:

– Docker engine– Compose– Machine– Swarm– Distribution (Docker registry)– libnetwork– libcontainer (prior to OCI)– Opencontainers/runC– Docker-py

3.AN OPEN CLOUD

IBM Container Cloud, built on Docker

• Easily host your Docker containers in IBM’s public cloud offering

• Manages the full container lifecycle

• Utilizes the standard Docker API
