今天小编给大家分享一下怎么干净的卸载docker的相关知识点，内容详细，逻辑清晰，相信大部分人都还太了解这方面的知识，所以分享这篇文章给大家参考一下，希望大家阅读完这篇文章后有所收获，下面我们一起来了解一下吧。
先上服务器环境信息：
卸载的原因：
宿主机过段时间就磁盘100%了，导致continart异常退出，后来找了很多解决方案，才发现是安装docker的时候有个配置文件错误（正常的应该是|storage driver: overlay2）。
上干货：
①卸载
yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-selinux \
docker-engine-selinux \
docker-engine
rm -rf /etc/systemd/system/docker.service.d
rm -rf /var/lib/docker
rm -rf /var/run/docker②安装

# this script is meant for quick & easy install via:
# $ curl -fssl get.docker.com -o get-docker.sh
# $ sh get-docker.sh
#
# for test builds (ie. release candidates):
# $ curl -fssl test.docker.com -o test-docker.sh
# $ sh test-docker.sh

# note: make sure to verify the contents of the script
# you downloaded matches the contents of install.sh
