How to install docker in Linux

Apr 25, 2023 pm 03:55 PM

Docker is a very popular containerization technology that can easily create, deploy and run applications. It is widely used in development, testing and production environments. Installing Docker in a Linux system is also very simple. This article will introduce how to install Docker in different Linux distributions.

1. Ubuntu

There are many ways to install Docker in Ubuntu, the following are two of them:

  1. Install the official Docker apt package

Use the apt-get command to install the official Docker apt package:

$ sudo apt-get update

$ sudo apt-get install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

$ sudo apt-get update

$ sudo apt-get install docker-ce docker-ce-cli containerd.io

The above command will download and install Docker CE and containerd.io from the official.

  1. Use the official installation script

You can also use the official installation script to install Docker:

$ curl -fsSL https://get.docker.com -o get-docker.sh

$ sudo sh get-docker.sh

The above command will be downloaded and executed from the Docker official website Install script.

2. CentOS

There are many ways to install Docker in CentOS. The following are two of them:

  1. Install the official Docker yum package

Use the yum command to install the official Docker yum package:

$ sudo yum install -y yum-utils

$ sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

$ sudo yum install docker-ce docker-ce-cli containerd.io

The above command will download and install Docker CE and containerd.io from the official.

  1. Use the official installation script

You can also use the official installation script to install Docker:

$ curl -fsSL https://get.docker.com -o get-docker.sh

$ sudo sh get-docker.sh

The above command will be downloaded and executed from the Docker official website Install script.

3. Other Linux distributions

In addition to Ubuntu and CentOS, the methods of installing Docker in other Linux distributions are similar. You can download the corresponding installation package or script from the Docker official website and install it.

4. Configuring Docker

After installing Docker, you still need to perform related configurations for normal use. The following are some common configurations:

  1. Start Docker

In Ubuntu, use the following command to start Docker:

$ sudo systemctl start docker

In CentOS, use the following Command to start Docker:

$ sudo systemctl start docker
  1. Set Docker to start automatically at boot

In Ubuntu, use the following command to set Docker to start automatically at boot:

$ sudo systemctl enable docker

In CentOS , use the following command to set Docker to start automatically at boot:

$ sudo systemctl enable docker
  1. Using Docker

After installing Docker, you can use the following command to verify whether the installation is successful:

$ sudo docker run hello-world

This command will download the hello-world image officially provided by Docker and start a container to run it.

Summary

Docker is a very popular containerization technology that makes it easy to create, deploy, and run applications. Installing Docker in a Linux system is also very simple. You only need to download the installation package or script and configure it accordingly. After installation, you can use Docker to create and manage containers with simple commands.

Docker on Linux: Containerization for Linux SystemsDocker 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 OrchestratorDocker: 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 DeploymentDocker'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

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 CasesDocker 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 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".
