This article introduces the relevant knowledge of "how to install the Docker environment for Kubernetes". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

This article describes the installation of the Docker environment under CentOS (7.6 64bit).

Download the installation script

Docker provides an automatic installation script that quickly installs the latest version of Docker-CE.

The script project is located at GitHub (https://github.com/docker/docker-install)), where you can learn more about the script.

Use the curl command to download the script:

Curl-fsSL https://get.docker.com-o get-docker.sh

This command downloads the script from the get.docker.com website locally and stores it in the get-docker.sh of the current directory.

Perform installation

The installation is an one-click installation, and the script automatically downloads the various dependent components you need.

Execute the following command to start the installation:

Sh get-docker.sh

After installation, docker does not run automatically, you need to run docker manually.

Start Docker

Systemd-related configuration files have been installed when docker is installed, so you only need to use systemctl to pull up the service:

Systemctl start docker

After startup, execute a command to check whether the installation is successful:

[root@ecs-d8b6 ~] # docker imagesREPOSITORY TAG IMAGE ID CREATED SIZE

If there is a similar output, the installation is successful.
