DK-docker 离线安装

# 系统: CentOS 7 
# 版本：3.10.0-1160.el7.x86_64

# setp 1: 如果之前已经安装过则需要删除，若没有则跳过。
# 检查是否安装过docker
sudo rpm -qa | grep docker
#[root@localhost ~]# rpm -qa | grep docker
#docker-ce-cli-20.10.18-3.el7.x86_64
#docker-ce-rootless-extras-20.10.18-3.el7.x86_64
#docker-scan-plugin-0.17.0-3.el7.x86_64
#docker-ce-20.10.18-3.el7.x86_64
​
# 卸载Docker
​
# 方式一: yum卸载
# 针对yum安装的docker
yum remove docker-ce docker-ce-cli containerd.io
# 删除docker相关文件
rm -rf /etc/docker
rm -rf /run/docker
rm -rf /var/lib/docker
rm -rf  /usr/libexec/docker
​
# 方式二: 手动卸载
# 杀死所有运行容器
docker kill `docker ps -a -q`
# 删除所有容器
docker rm `docker ps -a -q`
# 删除所有镜像
docker rmi `docker images -q`
# 停止 docker 服务
systemctl stop docker
# 卸载所以docker -*
rpm -e `rpm -qa | grep docker`
​
# step 2: 下载离线的安装包，都下载最新的且架构为x86_64
# https://download.docker.com/linux/centos/7/x86_64/stable/Packages/
# http://mirror.centos.org/centos/7/extras/x86_64/Packages/container-selinux-2.119.2-1.911c772.el7_8.noarch.rpm
# 需下载的包如下：
containerd.io-1.6.8-3.1.el7.x86_64.rpm
container-selinux-2.119.2-1.911c772.el7_8.noarch.rpm
docker-ce-20.10.9-3.el7.x86_64.rpm
docker-ce-cli-20.10.9-3.el7.x86_64.rpm
docker-ce-rootless-extras-20.10.9-3.el7.x86_64.rpm
docker-scan-plugin-0.9.0-3.el7.x86_64.rpm
