记一次Docker拉取镜像的报错

使用docker拉取镜像时，出现报错

[root@centos8 ~]# sudo docker pull mysql:8.0
Error response from daemon: Get "https://registry-1.docker.io/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

原因是需要配置镜像加速
修改/etc/docker/daemon.json为如下内容后解决：

{"registry-mirrors": ["https://<自己的镜像地址>.mirror.aliyuncs.com","https://docker.m.daocloud.io","https://dockerhub.icu","https://docker.anyhub.us.kg","https://docker.1panel.live"]
}

修改完成后，
需重新加载 deamon.json 配置文件

sudo systemctl daemon-reload

再重启docker

sudo systemctl restart docker

就ok啦~
