This article mainly explains "what is the overall structure of Docker". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn how the overall architecture of Docker is.

1. The user uses Docker Client to establish communication with Docker Daemon and send a request to the latter

As the main part of Docker architecture, 2.Docker Daemon first provides the function of Server so that it can accept requests from Docker Client; then Engine performs a series of tasks within Docker, each of which exists in the form of a Job

During the operation of 3.Job, when a container image is needed, the image is downloaded from Docker Registry, and the download image is stored in the form of Graph through the image management driver graphdriver; when a network environment needs to be created for Docker, a network management driver networkdriver is used to create and configure the Docker container network environment; when operations such as restricting Docker container running resources or executing user instructions are needed, it is done through execdriver

4.libcontainer is an independent container management package. Networkdriver and execdriver implement specific operations on the container through libcontainer.

5. After executing the command to run the container, an actual Docker container is running. The container has an independent file system, an independent and secure running environment, etc.

Thank you for your reading, the above is the content of "what is the overall structure of Docker". After the study of this article, I believe you have a deeper understanding of how the overall structure of Docker is, and the specific use needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
