error pulling image configuration: download failed after attempts=6: dial tcp 31.13.94.10:443: i/o timeout

首先设置国内的镜像源：复制下面直接执行

sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'

 {
  "registry-mirrors": [
          "https://ox288s4f.mirror.aliyuncs.com",
          "https://registry.docker-cn.com",
          "http://hub-mirror.c.163.com",
          "https://mirror.ccs.tencentyun.com"
  ]
}

EOF

sudo systemctl daemon-reload
sudo systemctl restart docker

或者

sudo service docker restart

 再拉取就快了
