docker卸載

1. 查詢安裝過的包

yum list installed | grep docker

我的顯示列表如下
docker.x86_64 2:1.13.1-103.git7f2769b.el7.centos
docker-client.x86_64 2:1.13.1-103.git7f2769b.el7.centos
docker-common.x86_64 2:1.13.1-103.git7f2769b.el7.centos

2. 刪除安裝的軟件包

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

3. 刪除鏡像容器
   rm -rf /var/lib/docker
