pull鏡像wordpress下來(lái)，但是出現(xiàn)如下錯(cuò)誤：

# 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)

發(fā)現(xiàn)是因?yàn)閐ocker加速器超時(shí)導(dǎo)致pull不下來(lái)

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"]

}

導(dǎo)致此問(wèn)題產(chǎn)生，主要是因?yàn)閲?guó)家把docker國(guó)外鏡像hub封掉了，導(dǎo)致鏡像pull不下來(lái)，為此，改用國(guó)內(nèi)的鏡像

# 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"]

}
