Running Docker on Linux: Installation and Configuration
Article Introduction：Installing and configuring Docker on Linux requires ensuring that the system is 64-bit and kernel version 3.10 and above, use the command "sudoapt-getupdate" and install it with the command "sudoapt-getupdate" and verify it with "sudoapt-getupdate" and. Docker uses the namespace and control groups of the Linux kernel to achieve container isolation and resource limitation. The image is a read-only template, and the container can be modified. Examples of usage include running an Nginx server and creating images with custom Dockerfiles. common

How to structure HTML for a CSS Grid layout
Article Introduction：To build an HTML structure for CSSGrid layout, you must first establish a clear parent-child relationship, use semantic tags and keep the structure flat. 1. Define a container with class name (such as divclass="grid-container") and place direct child elements as grid items in it; 2. Use semantic HTML5 elements (such as header, main, aside, etc.) to improve readability and accessibility, avoid unnecessary wrapping of divs; 3. Enable grid layout through CSS display:grid, and use grid-template-areas, grid-template-columns and gri

What is the difference between a Docker image and a Docker container?
Article Introduction：The difference between a Docker image and a container is: 1. The mirror is a static template, containing the files and instructions required to run the application; 2. The container is a running instance of the image, which is mutable; 3. The image is built through a Dockerfile and does not change unless rebuilt; 4. The container can be started, stopped, deleted, and can store temporary data; 5. Multiple containers can be run based on the same image, isolated from each other; 6. The image cannot directly perform network or storage operations, while the container can.

Detailed explanation of docker principle
Article Introduction：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.

HTML `template` Tag for Client-Side Templating
Article Introduction：Using HTML template tags as client templates is a lightweight, dependency-free dynamic content insertion scheme. 1. template is a lazy container introduced by HTML5, and the internal content will not be parsed or rendered; 2. Get and clone its content through JavaScript, fill in the data and insert it into the DOM, which is suitable for repeated structures such as user lists; 3. When using it, scripts, styles and data bindings need to be processed manually; 4. It is suitable for small projects or low-complexity components, while large projects are recommended to use frameworks such as React/Vue instead.

How to create a responsive HTML5 gallery
Article Introduction：Creating responsive HTML5 galleries requires no complex frameworks, just use semantic HTML and modern CSS. First, build a basic HTML structure containing the image container, and add a viewport meta tag to ensure mobile adaptation; then use CSSGrid to set the grid-template-columns:repeat(auto-fit,minmax(250px,1fr)) of CSSGrid to achieve an adaptive grid layout, cooperate with gap to control spacing, maintain image proportions through object-fit:cover, and improve interactive experience with hover scaling; at the same time, optimize performance, use compressed images, alt text and loading=&qu

What is Docker and what is its architecture?
Article Introduction：Docker is a platform that allows developers to build, run and manage applications in containers. Its core structure includes DockerEngine, mirroring and containers, client-server architecture, and namespace-based isolation mechanism. 1.DockerEngine is a core component, including a daemon running in the background (responsible for building images and running containers), a RESTAPI interface and a command line client (CLI). 2. Mirror is a static template that contains the application and its dependencies. The container is a running instance of the image. Multiple containers can originate from the same image, and the image is built through the Dockerfile. 3. Docker uses the client-server architecture, the CLI communicates with the daemon through the API, and can also connect to remote guards.
