1.拉取镜像报错

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)

2.切换镜像源(需要重启docker)

修改/etc/docker/daemon.json文件

mkdir -p /etc/docker
cat > /etc/docker/daemon.json <<'EOF'
{
  "registry-mirrors": [
    "https://docker.1ms.run",
    "https://docker-0.unsee.tech",
    "https://docker.m.daocloud.io"
  ],
  "log-driver": "json-file",
  "log-opts": {
      "max-size": "10m",
      "max-file": "3"
   },
  "live-restore": true,
  "features": { "buildkit": true }
}
