如何保证 docker daemon重启，但容器不重启

使用新版本的docker, 比如 1.12.6

然后在/etc/docker/daemon.json中添加"live-restore": true选项，比如：

{
    "log-level": "warn",
    "selinux-enabled": false,
    "insecure-registries": [
        "10.213.42.254:10500",
        "10.209.224.13:10500"
    ],
    "storage-driver": "devicemapper",
    "storage-opts": [
        "dm.basesize=100G",
        "dm.loopdatasize=1T",
        "dm.loopmetadatasize=10G",
        "dm.thinpooldev=/dev/mapper/docker-thinpool",
        "dm.use_deferred_removal=true",
        "dm.use_deferred_deletion=true"
    ],
    "live-restore": true,
    "exec-opts": [
        "native.cgroupdriver=systemd"
    ]
}

然后在/usr/lib/systemd/system/docker.service中添加：

# kill only the docker process, not all processes in the cgroup
KillMode=process

这样，我们就可以重启docker daemon，而不影响运行在其中的container了。
