如何在CentOS7中更改docker守护进程根目录

我在CentOS7中运行docker。如何在CentOS7中更改docker守护进程根目录

我想将我的基本目录从/var/lib/docker更改为/data/docker。

我发现this从官方网站指南，但不知道如何将这个应用到我的情况。

我只是在/etc/docker/中新建daemon.json。之后，当我试图运行守护进程发生错误。

跟着是systemctl status -l docker.service。

● docker.service - Docker Application Container Engine 
    Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled) 
    Active: failed (Result: exit-code) since Thu 2017-04-27 15:07:41 KST; 47s ago 
    Docs: https://docs.docker.com 
    Process: 42547 ExecStart=/usr/bin/dockerd (code=exited, status=1/FAILURE) 
Main PID: 42547 (code=exited, status=1/FAILURE) 

Apr 27 15:07:41 DCSF-DEV08 systemd[1]: Starting Docker Application Container Engine... 
Apr 27 15:07:41 DCSF-DEV08 dockerd[42547]: unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives don't match any configuration option: default-ulimits 
Apr 27 15:07:41 DCSF-DEV08 systemd[1]: docker.service: main process exited, code=exited, status=1/FAILURE 
Apr 27 15:07:41 DCSF-DEV08 systemd[1]: Failed to start Docker Application Container Engine.

Apr 27 15:07:41 DCSF-DEV08 systemd[1]: docker.service failed.

所以，我怎么能解决这个问题？（我想知道什么是守护进程默认设置时，我就跑systemctl start docker不/etc/docker/daemon.json）

========= EDIT = ==================

我目前的码头daemon.js。

}

我改变的唯一的事情是，因为我只是想改变根目录。（我想将其他人设为默认值default表示与systemctl start docker相同的配置）

你放什么在你的'的/ etc /泊坞窗/ daemon.json'？ – kstromeiraos

@JoséAntonioLópez谢谢。我把我的守护进程文件内容。感觉像填补了空白的领域，但我不知道该填什么。我想使用默认值 –

该文件会覆盖默认的泊坞窗配置。您不需要放置所有字段，因为这会导致您的情况出现错误配置。检查我的答案。 – kstromeiraos

编辑/etc/docker/daemon.json。

，我们只为以下内容：

{ 
    "graph": "/data/docker" 
}

重启码头工人守护进程：sudo service docker restart
