Docker process viewing method: 1. Docker CLI command: docker ps; 2. Systemd CLI command: systemctl status docker; 3. Docker Compose CLI command: docker-compose ps; 4. Process Explorer (Windows); 5. /proc directory (Linux).
How to view Docker processes
There are many ways to view Docker processes:
1. Docker CLI
CLI command: docker ps
Output:
<code>CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 9b898fd ubuntu:16.04 "/bin/sh -c 'echo H'" 10 minutes ago Up 10 minutes 0.0.0.0:80->33333/tcp lab01</code>
2. Systemd
CLI command: systemctl status docker
Output:
<code>● docker.service - Docker Application Container Engine Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2023-03-08 15:12:26 PST; 9s ago Main PID: 1076 (dockerd) CGroup: /system.slice/docker.service └─1076 /usr/bin/dockerd Mar 08 15:12:26 hostname dockerd[1076]: time="2023-03-08T23:12:26.077651444Z" level=info msg="executing create container 9b898fd43c519e3d93678db6597befe79cd115b6e9c2d6b96ce165e8e084f1c5" container=9b898fd43c519e3d93678db6597befe79cd115b6e9c2d6b96ce165e8e084f1c5" image=ubuntu:16.04" Mar 08 15:12:26 hostname dockerd[1076]: time="2023-03-08T23:12:26.303290725Z" level=info msg="container 9b898fd43c519e3d93678db6597befe79cd115b6e9c2d6b96ce165e8e084f1c5" started" container=9b898fd43c519e3d93678db6597befe79cd115b6e9c2d6b96ce165e8e084f1c5" image=ubuntu:16.04"</code>
3. Docker Compose
CLI command: docker-compose ps
Output:
<code> Name Command State Ports ------------------------------------------------------------------------------ lab01_web_1 "/bin/sh -c 'echo …" Up 0.0.0.0:80->33333/tcp</code>
4. Process Explorer
On Windows: Using the Sysinternals Process Explorer tool, you can view Docker processes in the process list.
On Linux: View processes in the /proc directory.

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
Mastering Docker: A Guide for Linux UsersApr 18, 2025 am 12:08 AMUsing Docker on Linux can improve development efficiency and simplify application deployment. 1) Pull Ubuntu image: dockerpullubuntu. 2) Run Ubuntu container: dockerrun-itubuntu/bin/bash. 3) Create Dockerfile containing nginx: FROMubuntu;RUNapt-getupdate&&apt-getinstall-ynginx;EXPOSE80. 4) Build the image: dockerbuild-tmy-nginx. 5) Run container: dockerrun-d-p8080:80
Docker on Linux: Applications and Use CasesApr 17, 2025 am 12:10 AMDocker simplifies application deployment and management on Linux. 1) Docker is a containerized platform that packages applications and their dependencies into lightweight and portable containers. 2) On Linux, Docker uses cgroups and namespaces to implement container isolation and resource management. 3) Basic usages include pulling images and running containers. Advanced usages such as DockerCompose can define multi-container applications. 4) Debug commonly used dockerlogs and dockerexec commands. 5) Performance optimization can reduce the image size through multi-stage construction, and keeping the Dockerfile simple is the best practice.
Docker: Containerizing Applications for Portability and ScalabilityApr 16, 2025 am 12:09 AMDocker is a Linux container technology-based tool used to package, distribute and run applications to improve application portability and scalability. 1) Dockerbuild and dockerrun commands can be used to build and run Docker containers. 2) DockerCompose is used to define and run multi-container Docker applications to simplify microservice management. 3) Using multi-stage construction can optimize the image size and improve the application startup speed. 4) Viewing container logs is an effective way to debug container problems.

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),
