Docker容器拉取nginx镜像报错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)解决办法

解决docker容器拉取不到nginx镜像的问题

1. 编辑 Docker 配置文件

mkdir -p /etc/docker # 确保目录存在
vi /etc/docker/daemon.json

2. 粘贴以下配置（国内镜像源，JSON 语法要正确）
   {
   "registry-mirrors": ["https://dh-mirror.gitverse.ru"]
   }

3. 重启 Docker 生效
   systemctl daemon-reload
   systemctl restart docker

4. 直接拉取官方标签即可
   docker pull nginx:1.26.0
