First, check the system information:

[root@centos7-dev01 ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
Official documentation link:The hyperlink login is visible.

Uninstall the old version


Older versions of Docker are called docker or docker-engine. If these are installed, uninstall them along with their associated dependencies.

If yum reports that the packages are not installed, that's okay.

The content of /var/lib/docker/, including images, containers, volumes, and networks, will be retained. The Docker engine package is now called docker-ce.

Use Docker's repository and install it from there

Set up the repository, install the yum-utils package (which provides the yum-config-manager utility), and set up the stable repository.


Install the Docker engine with the following command:

Start docker and set it to turn on autoboot



(End)
