[Docker] Uninstallation of docker under linux

background

At present, docker technology has become a commonly used technology stack for developers. Whether it is the construction of various complex and changeable development environments that need to be dealt with during the development process, or the automated operation and maintenance required for the production and deployment process, it is inseparable from docker. This article briefly introduces the uninstallation method of docker under linux, which is used for daily query.

1. Find installed docker packages

yum list installed | grep docker

containerd.io.x86_64                 1.5.11-3.1.el7                    @docker-ce-stable
docker-ce.x86_64                     3:20.10.14-3.el7                  @docker-ce-stable
docker-ce-cli.x86_64                 1:20.10.14-3.el7                  @docker-ce-stable
docker-ce-rootless-extras.x86_64     20.10.14-3.el7                    @docker-ce-stable
docker-scan-plugin.x86_64            0.17.0-3.el7                      @docker-ce-stable
