1、调整镜像源

vi /etc/docker/daemon.json

配如下地址

{ "registry-mirrors": [ "https://2a6bf1988cb6428c877f723ec7530dbc.mirror.swr.myhuaweicloud.com", "https://docker.m.daocloud.io", "https://hub-mirror.c.163.com", "https://mirror.baidubce.com", "https://your_preferred_mirror", "https://dockerhub.icu", "https://docker.registry.cyou", "https://docker-cf.registry.cyou", "https://dockercf.jsdelivr.fyi", "https://docker.jsdelivr.fyi", "https://dockertest.jsdelivr.fyi", "https://mirror.aliyuncs.com", "https://dockerproxy.com", "https://mirror.baidubce.com", "https://docker.m.daocloud.io", "https://docker.nju.edu.cn", "https://docker.mirrors.sjtug.sjtu.edu.cn", "https://docker.mirrors.ustc.edu.cn", "https://mirror.iscas.ac.cn", "https://docker.rainbond.cc" ]
}

2、重新加载配置文件及docker服务

systemctl daemon-reload
systemctl restart docker
