What exactly is docker? What is docker? A brief description

Docker is a lightweight virtual machine that simulates the environment required for applications to run, simplifying the process of running and deploying applications in different environments. It achieves environmental consistency through resource isolation and namespace management, as well as independent packaging of applications. In addition, Docker provides container image update function to achieve seamless upgrades. Despite limitations, Docker still plays a crucial role in microservice architecture, continuous integration and cloud-native applications through optimization (such as multi-stage construction and network policy adjustment).

Docker and Kubernetes: A Technical Deep Dive

Docker and Kubernetes: A Technical Deep Dive

Docker and Kubernetes are key tools for modern software development and deployment. Docker simplifies application packaging and deployment through containerization, while Kubernetes is used for large-scale container orchestration and management. Using Docker and Kubernetes can significantly improve the scalability and management efficiency of your application.

Detailed explanation of docker principle

Detailed explanation of docker principle

Docker uses Linux kernel features to provide an efficient and isolated application running environment. Its working principle is as follows: 1. The mirror is used as a read-only template, which contains everything you need to run the application; 2. The Union File System (UnionFS) stacks multiple file systems, only storing the differences, saving space and speeding up; 3. The daemon manages the mirrors and containers, and the client uses them for interaction; 4. Namespaces and cgroups implement container isolation and resource limitations; 5. Multiple network modes support container interconnection. Only by understanding these core concepts can you better utilize Docker.

Linux Containers: The Foundation of Docker

Linux Containers: The Foundation of Docker

LXC is the foundation of Docker, and it realizes resource and environment isolation through cgroups and namespaces of the Linux kernel. 1) Resource isolation: cgroups limit CPU, memory and other resources. 2) Environment isolation: namespaces provides independent process, network, and file system views.
