docker 组合收到意外的 HTTP 状态：503 服务不可用

Question

我正在尝试使用图像节点：16.13.1 创建一个 nodejs docker 应用程序。 （我曾尝试使用其他版本）。 我所在位置的网络速度很慢。 每次我尝试运行sudo docker-compose up -d时，下载一个大型中间容器/图像需要更长的时间。 直到那时，另一个图像重试了 3 次下载，然后突然命令失败并出现以下错误。

有时它会在 503 错误之前打印由对等方重置的连接。

Looks like its a docker instability of some restriction of your network (i test it here at 2 computers), you can also try to flush DNS from your computer, this DNS error already occurs in docker according this discussion https://forums.docker .com/t/docker-pull-503-service-unavailabl/2401
