Docker is a platform written in multiple programming languages, including: Go: for core components C: for low-level components Python: for CLI and management tools Shell: for scripts and configuration
What language is Docker written in?
Docker is an open source platform for developing, delivering, and running applications. It is written in several programming languages:
- Go: The core components of the Docker engine are written in Go, a concurrent, high-performance programming language.
- C: Some lower-level components, such as the container runtime, are written in C. C language is an efficient system-level programming language.
- Python: The Docker CLI (Command Line Interface) and some management tools are written in the Python language. Python is a readable and extensible programming language.
- Shell: Some scripts and configurations in Docker are written in the Shell language. Shell is a command line interpreter that allows users to execute commands and automate tasks.
Reasons for language selection
The Docker development team chose these languages for the following reasons:
- Go: For concurrency and high performance in core components.
- C: For efficiency and system-level access to underlying components.
- Python: Readability, extensibility, and flexibility for CLI and management tools.
- Shell: For simplicity and cross-platform compatibility in scripting and configuration.
By using multiple programming languages, Docker is able to optimize the performance, flexibility, maintainability and integration of its individual components with other ecosystem components.

The difference between Docker and Kubernetes is that Docker is a containerized platform suitable for small projects and development environments; Kubernetes is a container orchestration system suitable for large projects and production environments. 1.Docker simplifies application deployment and is suitable for small projects with limited resources. 2. Kubernetes provides automation and scalability capabilities, suitable for large projects that require efficient management.

Use Docker and Kubernetes to build scalable applications. 1) Create container images using Dockerfile, 2) Deployment and Service of Kubernetes through kubectl command, 3) Use HorizontalPodAutoscaler to achieve automatic scaling, thereby building an efficient and scalable application architecture.

The main difference between Docker and Kubernetes is that Docker is used for containerization, while Kubernetes is used for container orchestration. 1.Docker provides a consistent environment to develop, test and deploy applications, and implement isolation and resource limitation through containers. 2. Kubernetes manages containerized applications, provides automated deployment, expansion and management functions, and supports load balancing and automatic scaling. The combination of the two can improve application deployment and management efficiency.

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

The 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'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.

Select 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 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

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.
