Best practices for using Docker on Linux include: 1. Create and run containers using dockerrun commands, 2. Use DockerCompose to manage multi-container applications, 3. Regularly clean unused images and containers, 4. Use multi-stage construction to optimize image size, 5. Limit container resource usage to improve security, and 6. Follow Dockerfile best practices to improve readability and maintenance. These practices can help users use Docker efficiently, avoid common problems and optimize containerized applications.

Using Docker on Linux can improve development and deployment efficiency. 1. Install Docker: Use scripts to install Docker on Ubuntu. 2. Verify the installation: Run sudodockerrunhello-world. 3. Basic usage: Create an Nginx container dockerrun-namemy-nginx-p8080:80-dnginx. 4. Advanced usage: Create a custom image, build and run using Dockerfile. 5. Optimization and Best Practices: Follow best practices for writing Dockerfiles using multi-stage builds and DockerCompose.

The core of Docker monitoring is to collect and analyze the operating data of containers, mainly including indicators such as CPU usage, memory usage, network traffic and disk I/O. By using tools such as Prometheus, Grafana and cAdvisor, comprehensive monitoring and performance optimization of containers can be achieved.

DockerSwarm can be used to build scalable and highly available container clusters. 1) Initialize the Swarm cluster using dockerswarminit. 2) Join the Swarm cluster to use dockerswarmjoin--token:. 3) Create a service using dockerservicecreate-namemy-nginx--replicas3nginx. 4) Deploy complex services using dockerstackdeploy-cdocker-compose.ymlmyapp.

How to use Docker and Kubernetes to perform container orchestration of enterprise applications? Implement it through the following steps: Create a Docker image and push it to DockerHub. Create Deployment and Service in Kubernetes to deploy applications. Use Ingress to manage external access. Apply performance optimization and best practices such as multi-stage construction and resource constraints.

Docker FAQs can be diagnosed and solved through the following steps: 1. View container status and logs, 2. Check network configuration, 3. Ensure that the volume mounts correctly. Through these methods, problems in Docker can be quickly located and fixed, improving system stability and performance.

Docker is a must-have skill for DevOps engineers. 1.Docker is an open source containerized platform that achieves isolation and portability by packaging applications and their dependencies into containers. 2. Docker works with namespaces, control groups and federated file systems. 3. Basic usage includes creating, running and managing containers. 4. Advanced usage includes using DockerCompose to manage multi-container applications. 5. Common errors include container failure, port mapping problems, and data persistence problems. Debugging skills include viewing logs, entering containers, and viewing detailed information. 6. Performance optimization and best practices include image optimization, resource constraints, network optimization and best practices for using Dockerfile.

Docker security enhancement methods include: 1. Use the --cap-drop parameter to limit Linux capabilities, 2. Create read-only containers, 3. Set SELinux tags. These strategies protect containers by reducing vulnerability exposure and limiting attacker capabilities.

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),

DVWA
Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
