Linux Docker阿里云镜像仓库失效的解决

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 docker

pull 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

# 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脚本之家。
