Docker installation guides does contain three different ways of installing Docker. I want to know the exact difference between the three components.
Docker-Ce is a community edition of Docker, while Docker.Io is the enterprise edition. Docker-Ce is free and open source, while Docker.Io is available under a subscription. Docker-Ce is ideal for development and testing, while Docker.Io is better suited for production environments.
Docker is available in two editions: Community Edition (CE) Enterprise Edition (EE)
Docker Enterprise Edition (Docker EE) is designed for enterprise development and IT teams who build, ship, and run business-critical applications in production and at scale. Docker EE is integrated, certified, and supported to provide enterprises with the most secure container platform in the industry.
Yes, “Docker CE (Community Edition)” is the same as “Docker Desktop” and yes, this all sounds confusing. But the download page makes it somewhat clearer: Docker CE for Mac is an easy-to-install desktop app for building, debugging, and testing Dockerized apps on a Mac.
Docker CE (Community Edition) is the simple classical OSS (Open Source Software) Docker Engine.
Docker EE (Enterprise Edition) is Docker CE with certification on some systems and support by Docker Inc.
Docker CS (Commercially Supported) is kind of the old bundle version of Docker EE for versions <= 1.13.
Take a look at this blog post and this other one about Docker CE & Docker EE.
"What is Docker Enterprise Edition?
Docker Enterprise Edition comes in three versions: basic, standard and advanced. The Basic edition comes with the Docker platform, support and certification, while the Standard and Advanced version add additional features such as container management (Docker Datacenter) and Docker Security Scanning.
Docker EE is supported by Alibaba, Canonical, HPE, IBM, Microsoft and by a network of regional partners. Those who want to test Docker EE can download a trial version for free from the official site.
Docker is also offering a certification program to help third-party vendors in ensuring their products work with Docker EE.
What is Docker Community Edition?
Docker Engine has been renamed to Docker Community Edition, and, as the name suggests, it’s a do-it-yourself, community supported version of Docker that’s available for free of cost.
The community edition will be available in two versions: Edge and Stable. Edge will be released each month with the latest features. Stable will be released on a quarterly basis. While Edge will receive security updates and bug fixes for the current release, the stable version will get similar updates for four months after the initial release. This update cycle will give users a big enough window to plan upgrades from older versions.
While the two versions are targeted at different audiences, there isn’t much, or any, difference at source code level. “Both Docker EE and CE are based on the open source Docker project, which is developed in the open with Docker’s community of partners and contributors, and this forms the open, modular core of all Docker CE and EE editions,” said Messina."
Also, take a look at the resources here and the official Docker documentation.
