solution
停止docker
[root@localhost file-center-wf-monitor]# systemctl stopstop docker
重装docker
卸载docker及关键依赖
yum list installed | grep docker
yum remove docker-engine.x86_64
yum remove docker-engine-selinux.noarch
yum remove docker-engine.x86_64 docker-client.x86_64 docker-common.x86_64
yum remove container-selinux.noarch
删除docker 相关文件
rm -rf /var/lib/docker/
rm -rf /var/lib/docker
rm -rf /data0/docker_images/overlay2/*
rm -rf /data0/docker_images/*
rm -rf /etc/sysconfig/docker*
rm -rf /etc/systemd/system/docker.service.d
不卸载会导致安装不上
Package(s) docker available, but not installed.
不删除可能导致卸载不完全
安装docker
yum -y install docker
调整配置
[root@localhost file-center-wf-monitor]# vim /etc/docker/daemon.json
{
"graph": "/data0/docker_images",
"storage-driver": "overlay"
}
重载服务
systemctl daemon-reload
重启docker
service [start|restart] docker
查看docker状态
systemctl status docker
conclusion
本次问题根源是因为机器上某目录不可用，推测是由于历史docker版本残留导致
调整docker graph后，问题解决。
本文记录为解决当前问题过程中，所遇到的一系列问题和对应的操作。
yum安装docker，如果机器比较干净，安装会很顺利；如果历史安装过docker，会出现一系列问题。可以分别卸载docker的子package，并手动清除残留信息解决。
docker 镜像存储路径一定调整到系统数据盘，不然分分钟打满系统盘。
journalctl -xe 可以看到service信息（docker/mesos）
docker invalid argument不一定是启动的参数错误，一般不必调整/etc/systemd/system/docker.service.d/storage.conf 、/etc/sysconfig/docker-storage、/etc/sysconfig/docker 和 /etc/docker/daemon.json等文件。
/etc/sysconfig/docker配置可以关闭docker的selinux模式
# OPTIONS='--selinux-enabled --log-driver=journald --signature-verification=false'
OPTIONS='--log-driver=journald --signature-verification=false'
/etc/sysconfig/docker-storage配置可以调整docker存储（挂载目录）模式
DOCKER_STORAGE_OPTIONS=
/etc/sysconfig/docker-network配置可以调整docker网络模式
通过/etc/systemd/system/docker.service.d/***.conf下的对应文件进行配置，同样生效
docker启动时，本地目录权限、状态、挂载都应确认清楚，避免发生异常。
