Operation and MaintenanceDockerWhat should I do if the docker image cannot be accessed after it is started?What should I do if the docker image cannot be accessed after it is started?
Solution:
Edit the configuration file
vi /etc/sysctl.conf
or
vi /usr/lib/sysctl.d/00-system.conf
Add the following code:
net.ipv4.ip_forward=1
Restart the network service
systemctl restart network
Check whether the modification is successful
sysctl net.ipv4.ip_forward
If the return value is "net.ipv4.ip_forward = 1", it means success.

Running Docker on Linux: Installation and ConfigurationApr 26, 2025 am 12:12 AMInstalling 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
Why Use Docker? Benefits and Advantages ExplainedApr 25, 2025 am 12:05 AMThe reason for using Docker is that it provides an efficient, portable and consistent environment to package, distribute, and run applications. 1) Docker is a containerized platform that allows developers to package applications and their dependencies into lightweight, portable containers. 2) It is based on Linux container technology and joint file system to ensure fast startup and efficient operation. 3) Docker supports multi-stage construction, optimizes image size and deployment speed. 4) Using Docker can simplify development and deployment processes, improve efficiency and ensure consistency across environments.
Docker in Action: Real-World Examples and Use CasesApr 24, 2025 am 12:10 AMDocker's application scenarios in actual projects include simplifying deployment, managing multi-container applications and performance optimization. 1.Docker simplifies application deployment, such as using Dockerfile to deploy Node.js applications. 2. DockerCompose manages multi-container applications, such as web and database services in microservice architecture. 3. Performance optimization uses multi-stage construction to reduce the image size and monitor the container status through health checks.
Docker vs. Kubernetes: Use Cases and ScenariosApr 23, 2025 am 12:11 AMSelect Docker in a small project or development environment, and Kubernetes in a large project or production environment. 1.Docker is suitable for rapid iteration and testing, 2. Kubernetes provides powerful container orchestration capabilities, suitable for managing and expanding large applications.
Docker on Linux: Containerization for Linux SystemsApr 22, 2025 am 12:03 AMDocker is important on Linux because Linux is its native platform that provides rich tools and community support. 1. Install Docker: Use sudoapt-getupdate and sudoapt-getinstalldocker-cedocker-ce-clicotainerd.io. 2. Create and manage containers: Use dockerrun commands, such as dockerrun-d--namemynginx-p80:80nginx. 3. Write Dockerfile: Optimize the image size and use multi-stage construction. 4. Optimization and debugging: Use dockerlogs and dockerex
Docker: The Containerization Tool, Kubernetes: The OrchestratorApr 21, 2025 am 12:01 AMDocker is a containerization tool, and Kubernetes is a container orchestration tool. 1. Docker packages applications and their dependencies into containers that can run in any Docker-enabled environment. 2. Kubernetes manages these containers, implementing automated deployment, scaling and management, and making applications run efficiently.
Docker's Purpose: Simplifying Application DeploymentApr 20, 2025 am 12:09 AMThe purpose of Docker is to simplify application deployment and ensure that applications run consistently in different environments through containerization technology. 1) Docker solves the environmental differences problem by packaging applications and dependencies into containers. 2) Create images using Dockerfile to ensure that the application runs consistently anywhere. 3) Docker's working principle is based on images and containers, and uses the namespace and control groups of the Linux kernel to achieve isolation and resource management. 4) The basic usage includes pulling and running images from DockerHub, and the advanced usage involves managing multi-container applications using DockerCompose. 5) Common errors such as image building failure and container failure to start, you can debug through logs and network configuration. 6) Performance optimization construction
Linux and Docker: Docker on Different Linux DistributionsApr 19, 2025 am 12:10 AMThe methods of installing and using Docker on Ubuntu, CentOS, and Debian are different. 1) Ubuntu: Use the apt package manager, the command is sudoapt-getupdate&&sudoapt-getinstalldocker.io. 2) CentOS: Use the yum package manager and you need to add the Docker repository. The command is sudoyumininstall-yyum-utils&&sudoyum-config-manager--add-repohttps://download.docker.com/lin

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
