RALEIGH, N.C. & SAN FRANCISCO -- September 19, 2013

Red Hat, Inc. (NYSE: RHT), the world’s leading provider of open source
solutions, and dotCloud, the company behind Docker, an open source project to
pack, ship, and run any application as a lightweight container, today
announced a technical collaboration based on next-generation Linux Containers
technology to help drive the next evolution of OpenShift by Red Hat, Red Hat’s
Platform-as-a-Service (PaaS) offering. The collaboration between the
OpenShift, Red Hat Enterprise Linux, and Docker teams aims to combine the
versatile capabilities of Docker with the security and stability of Red Hat
Enterprise Linux Gears in OpenShift. OpenShift developers will benefit from a
simpler, more secure, lightweight, and portable environment for applications.

The OpenShift platform is built on the solid foundation of Red Hat Enterprise
Linux and provides secure, scalable, Linux Container-based multi-tenancy via
Red Hat Enterprise Linux Gears. On this platform, OpenShift offers support for
various programming languages, frameworks, Red Hat JBoss Middleware,
databases, and other services, and also enables OpenShift customers, partners,
and community members to integrate their own technology through OpenShift
cartridges. These features combine to power the OpenShift Online public PaaS
and bring OpenShift Enterprise private PaaS software to enterprise

Docker is an open source engine that enables any application and its
dependencies to be encapsulated as a lightweight container that will run in
almost any Linux environment: bare metal, virtualized, public cloud, or
private cloud. Docker’s user space library and utilities tool chain takes
advantage of both Linux Container enhancements found in the modern Linux
kernel and innovations found in the operating system such as the file system
and namespace layers. Docker uses this foundation in the Linux kernel to
provide lightweight runtime environments and offer a simple user experience,
focused on getting the maximum benefit from the operating system in a highly
portable manner.

Docker and OpenShift currently leverage the same building blocks to implement
containers, such as Linux kernel namespaces and resource management with
Control Groups (cGroups). Red Hat Enterprise Linux Gears in OpenShift use
Security-Enhanced Linux (SELinux) access control policies to provide secure
multi-tenancy and reduce the risk of malicious applications or kernel

Through the collaboration, Red Hat and dotCloud are working together on
several joint community efforts, including:

  *Packaging Docker for the Fedora Project, a Red Hat sponsored and
    community-supported open source collaboration. Red Hat and dotCloud are
    collaborating with members of the Fedora Project community to package
    Docker for Fedora, making Docker available for all Fedora users with
    upcoming releases, and also providing the initial packaging work that will
    ultimately enable Docker to more easily build and deploy on Red Hat
    Enterprise Linux.
  *Collaboration on filesystem dependencies, specifically designed to remove
    Docker’s dependency on AuFS (Advanced Multi Layered Unification
    Filesystem) to meet mission-critical requirements from enterprise
    customers. Together, Red Hat and dotCloud have developed a new approach to
    provisioning based on the device-mapper thin provisioning technology
    included in Fedora, Red Hat Enterprise Linux, and other distributions.
    This approach provides the same elegant user experience in a way that is
    more compatible with upstream kernel versions.
  *Collaboration on container provisioning, resulting in Red Hat’s work to
    enable libvirt, the open source virtualization API project, as an option
    for creating containers within Docker, bringing enterprise-grade
    networking capabilities along with it. This approach will enable users to
    take full advantage of the robust networking capabilities of libvirt while
    maintaining the user experience of Docker provisioning.
  *Collaboration on OpenShift to integrate Docker with OpenShift’s cartridge
    model for application orchestration. This integration will combine the
    power of Docker containers with OpenShift's ability to describe and manage
    multi-container applications, enabling customers to build more
    sophisticated applications with enhanced portability.

Ashesh Badani, general manager, Cloud, Red Hat

"Developers want PaaS offerings that enable them to design and code
applications without losing time on technology integration and how their
application infrastructure is architected. They want applications that are
truly portable and will run wherever they want. Through our collaboration on
Docker, we’re bringing innovation from the community to OpenShift, our
enterprise-class PaaS offerings, to reinforce our goal of bringing operational
efficiency and flexibility to developers.”

Ben Golub, Chief Executive Officer, dotCloud

"The collaboration between dotCloud and Red Hat is an exciting development
both for Docker as well as PaaS and containerization in general. We are
thrilled by the level of hands-on contribution we’ve seen from the RHEL,
Fedora, and OpenShift teams at RedHat, and believe the combination will bring
unique capabilities to further accelerate application development."
