The container ecosystem


In this chapter, we will talk about a few actors of the container ecosystem.

We have (arbitrarily) decided to focus on two groups:

  • the Docker ecosystem,

  • the Cloud Native Computing Foundation (CNCF) and its projects.

Moby vs. Docker

  • Docker Inc. (the company) started Docker (the open source project).

  • At some point, it became necessary to differentiate between:

    • the open source project (code base, contributors...),

    • the product that we use to run containers (the engine),

    • the platform that we use to manage containerized applications,

    • the brand.

Exercise in brand management


  • What is the brand of the car on the previous slide?

  • What kind of engine does it have?

  • Would you say that it's a safe or unsafe car?

  • Harder question: can you drive from the US West to East coasts with it?

The answers to these questions are part of the Tesla brand.

What if ...

  • The blueprints for Tesla cars were available for free.

  • You could legally build your own Tesla.

  • You were allowed to customize it entirely.

    (Put a combustion engine, drive it with a game pad ...)

  • You could even sell the customized versions.

  • ... And call your customized version "Tesla".

Would we give the same answers to the questions on the previous slide?

From Docker to Moby

  • Docker Inc. decided to split the brand.

  • Moby is the open source project.

    (= Components and libraries that you can use, reuse, customize, sell ...)

  • Docker is the product.

    (= Software that you can use, buy support contracts ...)

  • Docker is made with Moby.

  • When Docker Inc. improves the Docker products, it improves Moby.

    (And vice versa.)

Other examples

  • Read the Docs is an open source project to generate and host documentation.

  • You can host it yourself (on your own servers).

  • You can also get hosted on

  • The maintainers of the open source project often receive support requests from users of the hosted product ...

  • ... And the maintainers of the hosted product often receive support requests from users of self-hosted instances.

  • Another example: is a blogging platform that is owned and hosted online by Automattic. It is run on WordPress, an open source piece of software used by bloggers. (Wikipedia)

Docker CE vs Docker EE

  • Docker CE = Community Edition.

  • Available on most Linux distros, Mac, Windows.

  • Optimized for developers and ease of use.

  • Docker EE = Enterprise Edition.

  • Available only on a subset of Linux distros + Windows servers.

    (Only available when there is a strong partnership to offer enterprise-class support.)

  • Optimized for production use.

  • Comes with additional components: security scanning, RBAC ...


  • Non-profit, part of the Linux Foundation; founded in December 2015.

    The Cloud Native Computing Foundation builds sustainable ecosystems and fosters a community around a constellation of high-quality projects that orchestrate containers as part of a microservices architecture.

    CNCF is an open source software foundation dedicated to making cloud-native computing universal and sustainable.

  • Home of Kubernetes (and many other projects now).

  • Funded by corporate memberships.
