docker.service 的作业失败，因为控制进程退出并显示错误代码。参见“systemctl status docker.service”和“journalctl -xe”

Question

我是docker新手，看不懂这些错误。所以，如果需要更多信息，请告诉我。 `

[root@localhost docker]# systemctl start docker
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.

systemctl 状态 docker.service` 输出：

Docker版本：

Docker version 24.0.0-beta.1, build 33961a7

Linux内核版本：

Linux localhost.localdomain 3.10.0-1160.88.1.el7.x86_64 #1 SMP Tue Mar 7 15:41:52 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux

CentOS版本：

CentOS Linux release 7.9.2009 (Core)

我注意到

journalctl -xe

输出说

Status: invalid argument "<your" for "--registry-mirror" flag: invalid mirror: unsupported scheme "" in "%3Cyour"

，但我找不到修改它的地方。 我尝试重新安装 docker，删除

daemon.json

但它们没有用。

配置在其中一个 systemd 单元文件中设置。您可以在状态输出中看到用于定义单位的文件：

# systemctl status docker
● docker.service - Docker Application Container Engine
     Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)
    Drop-In: /etc/systemd/system/docker.service.d
             └─override.conf
     Active: active (running)  ...

Docker 拥有

/lib/systemd/system/docker.service

文件，因此您不想编辑它。但是，/etc/systemd/ 中的文件将在安装之间保留。编辑其中一个文件后，您需要在尝试重新启动服务之前使用

systemctl daemon-reload

将它们加载回 systemd。
