解决拉取镜像报 HTTP-408 错误

问题描述

在使用 Docker 下拉镜像时，出现解析错误，具体报错如下：

1
2
error parsing HTTP 408 response body: invalid character '<' looking for beginning of value: "<html><body><h1>408 Request Time-out</h1>\nYour browser didn't send a complete request in time.\n</body></html>\n"
Error response from daemon: error parsing HTTP 408 response body: invalid character '<' looking for beginning of value: "<html><body><h1>408 Request Time-out</h1>\nYour browser didn't send a complete request in time.\n</body></html>\n"

问题分析

该报错的主要问题是响应超时，排查处理方法：

  1. 确保网络畅通，是否正常连接互联网；
  2. 修改 /etc/docker/daemon.json 添加其他国内镜像仓库，因为官方的可能访问超时；
  3. 命令行输入 docker login，登录自己的 docker hub 账号，因官方有限制镜像拉取次数；
