docker pull 镜像问题

问题一：pull镜像报错:time out

分析：源问题，网络不稳定，更换加速源，地址：/etc/docker/daemon.json

解决：更换地址，如下，然后敲：docker daemon-reload && docker restart docker

{"registry-mirrors": ["https://docker.m.daocloud.io/","https://huecker.io/","https://dockerhub.timeweb.cloud","https://noohub.ru/","https://dockerproxy.com","https://docker.mirrors.ustc.edu.cn","https://docker.nju.edu.cn","https://xx4bwyg2.mirror.aliyuncs.com","http://f1361db2.m.daocloud.io","https://registry.docker-cn.com","http://hub-mirror.c.163.com"]
}

问题二：重启docker报错

分析：报错为配置文件内容有错误。注意配置文件编写时的标点符号。
