Boot2Docker is a lightweight Linux distribution designed specifically for Docker. It is an operating system used to solve the problem that Windows or OS X users cannot install Docker. Boot2Docker runs completely in memory, is 24M in size, and only takes 5-6 seconds to start.

The operating environment of this tutorial: linux5.9.8 system, docker-1.13.1 version, Dell G3 computer.

Boot2Docker is a lightweight Linux distribution based on Tiny Core Linux. It is an operating system that solves the problem that Windows or OS X users cannot install Docker. Boot2Docker is specially prepared for Docker, runs completely in memory, is 24M in size, and only takes 5-6 seconds to start.

Boot2Docker needs to run in VirtualBox. For specific installation, please refer to the official documentation (https://github.com/boot2docker/boot2docker#installation).

Step one: Download bootdocker2.exe and install it

https://github.com/boot2docker/windows- installer/releases

After the installation is complete, there will be a startup script on the desktop. Opening it will start the virtual machine vbox and run the boot2docker inside. Here

Note: This system is only a readable system, and changes to the system will not be retained. For example, if I execute: mkdir, work, and then restart, I will not see the wrok folder, but all the docker images and operations will be retained. On the virtual hard disk, it will not be lost.

Step 2: Mount the shared folder

This system has a default mounting mechanism

Share name: c/User will be mounted to /c/Users

Look at the picture: In this way, I map /c/Users in the virtual machine to E:\virual\docker (its share name is c/Users)

There are some more below:
Users Mount to /Users
/Users Mount to /Users
c/Users Mount to /c/Users
/c/Users Mount to /c/Users
c:/Users Mount to /c/Users

In this way, the windows directory is mounted to boot2docker. The next step is docker.

Docker on Linux: Containerization for Linux SystemsApr 22, 2025 am 12:03 AM

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

Docker: The Containerization Tool, Kubernetes: The OrchestratorApr 21, 2025 am 12:01 AM

Docker 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 AM

The 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 AM

The 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 AM

Using 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 AM

Docker 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 AM

Docker 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.

How to start containers by dockerApr 15, 2025 pm 12:27 PM

Docker container startup steps: Pull the container image: Run "docker pull [mirror name]". Create a container: Use "docker create [options] [mirror name] [commands and parameters]". Start the container: Execute "docker start [Container name or ID]". Check container status: Verify that the container is running with "docker ps".
