This was discussed and agreed in #246. It will probably break a few outstanding PRs as well as a few external links but it's for the better good long term.

# 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.

## The Docker ecosystem
|
|
|
|
|

|
|
|
|
## 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
|
|
|
|
Questions:
|
|
|
|
--
|
|
|
|
- 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 readthedocs.org.
|
|
|
|
- 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:
|
|
|
|
*WordPress.com 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 ...
|

## The CNCF
|
|
|
|
- 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.
