pull镜像wordpress下来，但是出现如下错误：
# docker pull wordpress:latest
Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaitin headers)
查看日志，发现出现如下错误：
#tailf /var/log/messages

发现是因为docker加速器超时导致pull不下来 查看加速器：/etc/docker/daemon.json
# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://registry.docker-cn.com"],
"insecure-registries": ["10.0.0.12:5000"]
}
导致此问题产生，主要是因为国家把docker国外镜像hub封掉了，导致镜像pull不下来，为此，改用国内的镜像
# cat /etc/docker/daemon.json
{
"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn/","https://hub-mirror.c.163.com","https://registry.docker-cn.com"],
"insecure-registries": ["10.0.0.12:5000"]
}
