Question

我需要在Fedora 25系统启动期间启动dockerd。

我在Fedora 25 Server Edition中安装了docker-engine。

Docker版本：

Client:
 Version:      1.13.0
 API version:  1.25
 Go version:   go1.7.3
 Git commit:   49bf474
 Built:        Tue Jan 17 09:58:06 2017
 OS/Arch:      linux/amd64

Server:
 Version:      1.13.0
 API version:  1.25 (minimum version 1.12)
 Go version:   go1.7.3
 Git commit:   49bf474
 Built:        Tue Jan 17 09:58:06 2017
 OS/Arch:      linux/amd64
 Experimental: false

我已经通过自定义位置存储了docker文件，所以我以前用 dockerd 启动以下方法

dockerd -g /u01/docker

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

像：

dockerd -g /u01/docker

如何更改github init脚本，或者您可以建议如何编写新脚本吗？

Answer 1

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

<强> docker.service：

    [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在系统启动时启动。

fedora中的dockerd init脚本
