我要评论docker阿里云镜像仓库失效
写在前面，这个是我很早之前在vmware安装的linux7,通过yum 安装的docker
但是今天怎么都无法pull镜像，报错如下：
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
问题排查
检查网络是否通常
ping www.baidu.com
设置阿里云镜像加速地址
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'eof'
{
"registry-mirrors": ["https://95lnapms.mirror.aliyuncs.com"]
}
eof
sudo systemctl daemon-reload
sudo systemctl restart dockerpull 镜像仍然报错
查看docker是否成功设置镜像地址
docker info | grep registry -a3
查看docker 日志看报错问题
# 通过yum 安装的docker日志在 /var/log/messages
tail -500f /var/log/messages
# 直接查看报错信息
oct 9 21:53:38 localhost dockerd: time="2024-10-09t21:53:38.438867024-04:00" level=info msg="attempting next endpoint for pull after error: denied: this request is forbidden. please proceed to https://help.aliyun.com/zh/acr/product-overview/product-change-acr-mirror-accelerator-function-adjustment-announcement to view the announcement." spanid=51a7bcba48f43406 traceid=92a5ccfd35082cb24dd48789f28e858a

# 大概意思就是尝试从阿里云镜像仓库拉取了，但是报错了，然后在从docker原来的镜像仓库拉去，可能网络不通也拉取不到
替换新的镜像仓库地址
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'eof'
{
"registry-mirrors": [
"https://do.nark.eu.org",
"https://dc.j8.work",
"https://docker.m.daocloud.io",
"https://dockerproxy.com",
"https://docker.mirrors.ustc.edu.cn",
"https://docker.nju.edu.cn"
]
}
eof
sudo systemctl daemon-reload总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持代码网。
