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
