It appears you’ve provided information about Docker Engine, an open-source containerization technology. Here’s a summary of the key points from the text:
Repackaged Open-Source Software: Docker Engine is described as a repackaged open-source software product. This suggests that Docker Engine takes an open-source software base and possibly adds additional features or services for which charges apply, specifically for technical support.
Docker Engine Components: Docker Engine operates as a client-server application with several components:
Server (dockerd): The server component runs as a long-running daemon process called dockerd. It manages and oversees containerization tasks.
APIs: Docker Engine provides APIs that define the interfaces programs can use to communicate with and control the Docker daemon.
Command Line Interface (CLI): Users interact with Docker Engine through a command line interface called docker. This CLI uses Docker APIs to issue commands to the Docker daemon.
Docker Objects: The Docker daemon, dockerd, is responsible for creating and managing Docker objects. These objects include images, containers, networks, and volumes. Docker containers are lightweight, portable, and can run applications in isolated environments.
Windows Server Support: Docker daemon can be installed on Windows Server. However, it’s important to note that when Docker daemon is installed on Windows Server, it is designed to run Windows containers exclusively, not Linux containers. This means it doesn’t include Docker components like buildx and compose, which are more commonly associated with Linux-based Docker setups.
This information provides an overview of Docker Engine and its components, particularly when used on Windows Server. It also mentions the possibility of additional charges for technical support, indicating that while Docker Engine is open source, support services may come at an additional cost.
