一、场景
在搭建Harbor镜像仓库的时候配置insecure-registries参数，需要重启容器，然后重启失败了
二、报错
docker启动命令启动失败
systemctl start docker报错如下
Job for docker.service failed because the control process exited with error code.See "systemctl status docker.service" and "journalctl -xe" for details.三、分析
1. Docker状态查看
使用命令查看docker状态
systemctl status docker输出主状态如下，好像也看不出是什么原因
● docker.service - Docker Application Container Engine Loaded: loaded (/usr/lib/systemd/system/docker.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Tue 2024-01-30 21:14:36 CST; 12h ago Docs: https://docs.docker.com Process: 4110 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock (code=exited, status=1/FAILURE) Main PID: 4110 (code=exited, status=1/FAILURE)Jan 30 21:14:36 k8s-master systemd[1]: docker.service: Service RestartSec=2s expired, scheduling restart.Jan 30 21:14:36 k8s-master systemd[1]: docker.service: Scheduled restart job, restart counter is at 3.Jan 30 21:14:36 k8s-master systemd[1]: Stopped Docker Application Container Engine.Jan 30 21:14:36 k8s-master systemd[1]: docker.service: Start request repeated too quickly.Jan 30 21:14:36 k8s-master systemd[1]: docker.service: Failed with result 'exit-code'.Jan 30 21:14:36 k8s-master systemd[1]: Failed to start Docker Application Container Engine.截图
2. 系统日志查看
然后还可以使用查看系统整体的最后两百行日志
tail -200f /var/log/messages可能内容多且拥挤所以没找到原因
3. Dockerd查看
使用dockerd命令查看问题
dockerd输出如下，这个命令好像能看出一些端倪，感谢某博主的这个dockerd命令，大家可根据输出内容百度查找适合自己的解决方法
unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives don't match any configuration option: insecure-registies前半段主要原因：unable to configure the Docker daemon with file /etc/docker/daemon.json:
大概意思就是说无法使用daemon.json文件配置docker的守护进程，就是这个json文件的问题
后半段具体原因：the following directives don't match any configuration option: insecure-registies
意思是因为重定向访问无法匹配配置参数insecure-registies，就是这个参数的问题
我的daemon.json文件内容如下：
到这里应该英文好的施主都能知道问题出在哪里了，我英语差且手残，英文单词registies是错误写法，正确的是registries
如果你跟我这个内容不一样，也是可以参考下面的解决方法
四、解决
1. 键值检查
本篇问题出现在键的单词写错了
正常daemon.json文件的内容是必须符合json格式要求的，且键值一一对应
键一般都是固定的写法，值则根据自己的情况填入
我将insecure-registies修改为正确的insecure-registries重启docker即解决了这个报错
2. 格式检查
如果你的问题是json文件的问题，但后面写的不是参数问题，键值无误，可检查一下json格式是否正确
将内容复制后粘贴到在线json格式检查网站上检查一下
如果格式错了可修正后重启docker
3. 删除或修改daemon.json文件
如果上面以及网上其他方法都不能解决问题，终极的方法就是这个了，前提是该文件的配置没有了也不会影响你docker的使用
但像我这样在k8s集群中使用的话，里面配置了k8s相关的参数，没有这个文件会影响k8s，就无法使用这个方式解决
方法如下
直接删除daemon.json，命令如下，但不建议这样做
rm -f /etc/docker/daemon.json为了后续还能改回来使用，可以修改格式使其失效
将daemon.json修改为daemon.text，等同于删除daemon.json
mv /ect/docker/daemon.json /etc/docker/daemon.text4. 启动Docker
最后重新启动docker
systemctl restart docker5. 查看Docker
systemctl status docker
五、演示
完整操作代码
