我需要dockerd在 Fedora 25 的系统引导期间启动。

我已经安装docker-engine在 Fedora 25 服务器版中。

我已经通过自定义位置存储了 docker 文件，所以我曾经为以下方法启动dockerd

dockerd -g /u01/docker

我看到这个初始化脚本 init1和init2 但是，它们只启动docker，我需要使用自定义位置启动 dockerd

喜欢：

dockerd -g /u01/docker

我如何更改该 github 初始化脚本，或者您能建议如何编写一个新脚本？

我自己找出解决方案

我找到默认的 docker.service 文件并更改为我们的自定义位置路径

我添加了这一行ExecStart=/usr/bin/dockerd -g /u01/docker而不是ExecStart=/usr/bin/dockerd

码头工人服务：

    [Unit]
    Description=Docker Application Container Engine
    Documentation=https://docs.docker.com
    After=network.target firewalld.service

    [Service]
    Type=notify
    # the default is not to use systemd for cgroups because the delegate issues still
    # exists and systemd currently does not support the cgroup feature set required
    # for containers run by docker
    ExecStart=/usr/bin/dockerd -g /u01/docker
    ExecReload=/bin/kill -s HUP $MAINPID
    # Having non-zero Limit*s causes performance problems due to accounting overhead
    # in the kernel. We recommend using cgroups to do container-local accounting.
    LimitNOFILE=infinity
    LimitNPROC=infinity
    LimitCORE=infinity
    # Uncomment TasksMax if your systemd version supports it.
    # Only systemd 226 and above support this version.
    #TasksMax=infinity
    TimeoutStartSec=0
    # set delegate yes so that systemd does not reset the cgroups of docker containers
    Delegate=yes
    # kill only the docker process, not all processes in the cgroup
    KillMode=process

    [Install]
    WantedBy=multi-user.target

之后我跑 

sytemctl daemon-reload
systemctl enable docker.service 
systemctl start docker.service

现在， docker start 在系统启动时启动。
