Docker Announces Orchestration for Multi-Container Distributed Apps [feedly]

Docker Announces Orchestration for Multi-Container Distributed Apps
// Docker Blog

New services accelerate development-to-deployment of applications atop any infrastructure, from on-premise virtualized data centers to public clouds

San Francisco, Calif.  and Amsterdam, NL.– December 4, 2014 – Docker, Inc., the company behind the open platform for distributed applications, today announced new, comprehensive platform services for orchestrating multi-container distributed applications. These comprehensive orchestration capabilities are designed to empower developers and sysadmins to create and manage a new generation of portable distributed applications that are rapidly composed of discrete interoperable Docker containers, have a dynamic lifecycle, and can scale to run in concert anywhere from the developer's laptop to hundreds of hosts in the cloud.

"As we evolve from applications created from a small number of Docker containers on a handful of hosts to large, multi-Docker container applications spread across clusters and diverse infrastructures, it is important that users don't lose the qualities that have made Docker so successful," said Solomon Hykes, CTO and founder of Docker and the Chief Maintainer of the Docker open source project. "This includes native and open interfaces, the ability to be portable across all environments, and through a common UI the power to leverage a broad ecosystem of 18,000 tools and 60,000 Dockerized apps."

Docker orchestration services are being previewed at DockerCon EU – the inaugural Docker user conference in Europe – and are backed by an unrivaled partner ecosystem which includes: Cisco, Digital Ocean, HP, IBM, Mesosphere, Microsoft and VMware.

Docker Platform Enhancements for Multi-Container Distributed Applications

Docker's orchestration capabilities build on the foundations of the open platform which established Docker containers as the industry standard for building discrete application services into interoperable and iterative components that can run anywhere. Docker's orchestration services are a reflection of the transformational shift that is occurring as organizations migrate from slow-evolving monolithic applications to Dockerized distributed applications. Orchestrating these distributed applications requires a native multi-container, multi-host approach with a common UI and tooling that works across infrastructures.

Comprehensive Orchestration Provides a Powerful New Approach to Application Development and Operations

Docker's orchestration capabilities are delivered through three new platform services that are designed to cover all aspects of the dynamic lifecycle of distributed applications, where new code or a new Dockerized service that changes application functionality can be put into production in minutes instead of months. While Docker's orchestration services are the most comprehensive on the market, their unique modular structure allows them to be accessible for both users – developers and sysadmins – and ecosystem partners.  For example, there is an explicit service focused on developers to help facilitate their creation of a distributed application stack, while another service is focused on clustering that speaks to the concerns of the operations team.

The three new orchestration services are:

  • Docker Machine: This service further expands the portability capabilities of distributed applications by providing the user the flexibility to provision any host with the Docker Engine, whether a laptop, a data center VM, or a cloud node. This saves a developer a significant amount of time in manual setup and custom scripting, resulting in faster iterations and compressing the development-to-deployment cycle.
  • Docker Swarm: Docker Swarm is a Docker-native clustering service that works with the Docker Engines, provisioned by the new Docker Machine service, and creates a resource pool of the hosts on which the distributed applications run. By automatically scheduling container workloads and allocating resources, Docker Swarm provides users with high-performance and availability while eliminating inefficient and error-prone manual resource management. Docker Swarm is unique in the industry as it is expressly designed for a continuous lifecycle from development to operations. It is structured in a way that a developer can test his clustered application across a few on-premise machines, while an operations team can use the same tooling to scale that same application across hundreds of hosts across diverse infrastructure. The Docker Swarm API supports pluggable clustering implementations, giving customers the ability to choose highly-scalable solutions like Mesosphere to orchestrate containers across tens thousands of nodes.
  • Docker Compose: This service provides developers with the ability to assemble applications from discrete, interoperable Docker containers completely independent of any underlying infrastructure, enabling distributed application stacks to be deployed anywhere and moved at any time. Defining a distributed application stack and its dependencies through a simple YAML configuration file converts what was an incredibly complex process into a simple one that can be executed in just a few keystrokes. This powerful capability means that new distributed applications can be spun up in minutes in stark contrast to conventional approaches where an application's time-to-market was measured in months if not years.

Open APIs and Open Design Create Opportunity for Broad Ecosystem

Open APIs for Docker's orchestration services expand collaboration opportunities for Docker's vibrant ecosystem, which has grown into hundreds of partners over the 19 months of the open source project. Aspects of the orchestration APIs were previously made available to infrastructure partners to help showcase reference implementations as part of Docker's open design process and are now being made available to the Docker partner ecosystem at DockerCon EU. This new set of APIs will also make it possible for standalone orchestration products to have their feature sets accessible through the Docker UI.

Docker's open design process is reflected in the three orchestration services, which have been shaped by direct input from the community to cover all aspects of multi-container development to deployment in a continuous application lifecycle.

Furthermore, the community involvement has structured these services to be modular, which provides users of Docker the flexibility to choose which service fits their application's requirements with the ability to leverage other orchestration tooling from the Docker ecosystem.

"Batteries Included, but Removable."  All Orchestration Services are Optional.

Consistent with Docker's layered, API-driven, open approach, users will have options when using each of these new orchestration services:

  1. "Batteries included": The user would run the default implementation of the service Docker includes in the release.
  2. "Batteries removable": Instead of running the default Docker implementation, some users may elect to use a third-party's implementation of clustering, scheduling, or any other service written to the orchestration APIs. This will help preserve portability and interoperability, while providing users with the flexibility to choose ecosystem technologies that best suit a particular use case.
  3. "Single Container Only": Even the use of multi-container orchestration APIs is optional. For organizations or vendors that only require a single Docker container approach, they can continue to use the Docker platform without changing the workflows they already have in place today. Even as the Docker project has expanded the set of capabilities around Docker, the community of developers working on single container functionality has tripled and the project will continue to invest resources on this use case.


The three Docker orchestration services are now available as Alpha releases.  These new capabilities are being demonstrated at DockerCon EU. APIs are now available for Docker Machine with others being made available in 1H, 2015. These three orchestration services are targeted for general availability in Q2, 2015.
