【Docker | 4】Docker Installation and Configuration Guide

written in front 

As a leading containerization technology, Docker has greatly changed the way modern applications are deployed and managed. Before you can start using Docker, you first need to install and configure Docker on different operating systems.

This article will provide detailed Docker installation and configuration steps, covering Linux, Windows and macOS platforms, and introduce how to configure Docker Daemon and Docker client to easily get started with Docker containerization technology.

1. Install and configure Docker on Linux

On Linux systems, Docker is usually installed using a package manager. Here are the steps to install Docker on common Linux distributions (e.g. Ubuntu, CentOS):

Step 1: Update the system package list

For Ubuntu:

sudo apt update

For CentOS:

sudo yum update

Step 2: Install Docker

For Ubuntu:

sudo apt install docker.io

For CentOS:

sudo yum install docker

Step 3: Start the Docker service

Excuting an order:

sudo systemctl start docker

Step 4:

Add the current user to the Docker group (optional, so users don't need to use sudo to run Docker commands)

sudo usermod -aG docker $USER

Step 5:

Configure Docker Daemon (optional)

The configuration file for Docker Daemon is located at /etc/docker/daemon.json. You can modify this file to configure the behavior of the Docker daemon as needed.

2. Install and configure Docker on Windows

Installing Docker on Windows uses Docker Desktop, which integrates the Docker engine, CLI tools, and some graphical interfaces. Here are the steps to install and configure Docker Desktop on Windows:

step 1:

Download Docker Desktop

Visit the Docker official website to download Docker Desktop and follow the installation wizard to install it.

Step 2:

Start Docker Desktop

After the installation is complete, start the Docker Desktop application.

Step 3:

Configure Docker Daemon (optional)

In Docker Desktop, you can access settings through the systray icon. Select "Settings" > "Docker Engine" from the menu, you can edit the configuration file in JSON format.

3. Install and configure Docker on macOS

Installing Docker on macOS is similar to Windows, using the Docker Desktop tool. Here are the steps to install and configure Docker Desktop on macOS:

step 1:

Download Docker Desktop

Visit the Docker official website to download Docker Desktop and follow the installation wizard to install it.

Step 2:

Start Docker Desktop

After the installation is complete, start the Docker Desktop application.

Step 3:

Configure Docker Daemon (optional)

In Docker Desktop, you can access settings through the Docker icon on the menu bar. Select "Preferences", then select the "Docker Engine" tab, you can edit the configuration file in JSON format.

Summarize

Following the guidelines in this article, you should now have successfully installed and configured Docker on different operating systems.

The cross-platform nature of Docker makes the development and deployment of container technology more convenient and efficient. Next, you can start using Docker to build, run, and manage containers, and enjoy the convenience and flexibility brought by containerization technology.
