linux环境卸载docker的方法如下：

yum remove docker \
                    docker-client \
                    docker-client-latest \
                    docker-common \
                    docker-latest \
                    docker-latest-logrotate \
                    docker-logrotate \
                    docker-selinux \
                    docker-engine-selinux \
                    docker-engine1 

rm -rf /etc/systemd/system/docker.service.d

rm -rf /var/lib/docker

rm -rf /var/run/docker





#列出docker安装过的相关包
sudo yum list installed | grep docker

#删除相关安装包
sudo yum -y remove docker-ce.x86_64

sudo yum -y remove docker-ce-selinux.noarch

#删除相关的镜像与容器
sudo rm -rf /var/lib/docker

sudo yum remove docker  docker-common docker-selinux docker-engine

接下来

1、查询docker已安装的包

yum list installed | grep docker

2、删除已安装的包

yum remove docker-ce.x86_64 ddocker-ce-cli.x86_64 -y

3、删除镜像/容器

rm -rf /var/lib/docker
