DOCKER - 3 Editions

Before going further with Docker, you need to install it — and that means choosing the right edition. There are over a dozen Docker editions today, and we'll look at the differences so you can pick the one that suits this course. We also clarify Community Edition (free) vs Enterprise Edition (paid, for large organisations), and what the stable and edge release channels mean.

CE vs EE, and the three install types

This course is built around Docker CE — the free, open-source version. Docker EE is the enterprise option: paid per node, suited to larger organisations that need a management GUI or 24/7 phone support. EE is available with monthly or yearly subscriptions; see docker.com/pricing for details. EE will be mentioned occasionally but is not the focus.

Three types of installations cover the lifecycle:

  • Direct — installed straight on the host OS. Historically Linux-only until Windows Server 2016 added native support.
  • Mac & Windows 10 desktop — a tool suite around Docker rather than a pure install. Under the hood, a small lightweight VM runs the Linux containers transparently because neither macOS nor Windows runs the Linux kernel natively.
  • Cloud — Docker for AWS, Azure or Google. The base OS is usually Linux, with vendor-specific integrations baked in.

This course focuses on Docker for Mac and Docker for Windows. Toward the end we'll spin up Swarm clusters in the cloud and look at deployment options there. For releases: edge is the monthly beta channel, supported only until the next edge ships; stable comes out roughly every six months and is supported for four months past the next release, giving you a comfortable one-month overlap to migrate. EE subscribers get much longer support windows on each version.

That's all for this video, but see you soon, for the next one.

Summary

This lesson introduces Docker's three main editions—Community Edition (free, open-source), Enterprise Edition (paid), and their availability across different platforms (Linux direct install, Mac, Windows, and cloud providers). The instructor explains the release schedule and support cycles, distinguishing between Stable versions (released every 5-6 months, 4 months support) and Edge versions (monthly, beta releases).

Key points

  • Docker Community Edition (CE) is the free, open-source version used throughout most of the course, while Enterprise Edition (EE) is a paid option designed for large organizations requiring managed support and graphical management interfaces.
  • Three installation types are available: direct installation on Linux, virtualized installations for Mac and Windows (using a lightweight VM to run Linux containers), and cloud-based options through AWS, Azure, or Google Cloud.
  • Stable releases come out every 5-6 months with 4 months of support; Edge (beta) versions are released monthly and supported only until the next version launches, requiring users to upgrade frequently.
  • Mac and Windows don't natively support Docker; they rely on a transparent virtual machine running behind the scenes to execute containers.
  • Enterprise Edition pricing is per-node and better suited for organizations with large server infrastructure; independent developers and small teams should use the free Community Edition.

FAQ

What is the difference between Docker Community Edition and Enterprise Edition?

Community Edition is free, open-source software ideal for developers and small teams. Enterprise Edition is a paid subscription (monthly or annual) that includes graphical management interfaces, 24/7 phone support, and longer version support cycles (approximately one year per release), making it more suitable for large organizations managing many servers.

How does Docker run on Mac and Windows if they don't natively support it?

Docker on Mac and Windows installs as a suite of tools that launches a lightweight virtual machine in the background, transparently running a Linux environment needed to execute Docker containers. Most users won't notice this VM due to its seamless integration.

What are Stable and Edge versions, and which should I use?

Stable versions release every 5-6 months and receive 4 months of support, making them reliable for production use. Edge versions release monthly as beta releases with support only until the next version launches. For most developers, Stable is the recommended choice; Edge is for those wanting the latest features and willing to upgrade frequently.
