从包含 Discourse 的服务器镜像恢复，但重建报错

支持
1

I backup a server image which discourse runs smoothly, and then restore on a new server with the backup, but when I rebuild app from discourse directory, it always gets a error to access git, the message is:

"cd /pups && git pull && /pups/bin/pups --stdin

fatal: unable to access ‘GitHub - discourse/pups: Simple yaml based bootstrapper for Linux machines’: Could not resolve host: github.com"

By the way, the network has no problem that I can access github, I wonder there’s a configuration contains the old server’s ip address in discourse, but I can’t find it

2

The host network has no problem, but the Docker one is busted.

Last week someone complained with a similar bug and the docker network wasn’t able to connect to the DHCP provided DNS, and setting it to a public DNS (like 8.8.8.8) solved it.

I have change the nameserver in resolv.conf and hosts, but it doesn’t work

5

Which resolve.conf? The docker container or the host?

Can the docker container ping that IP? If ICMP doesn’t reach it then UDP won’t.

6

I don’t know which one to configure

抱歉打扰了旧帖。我遇到了同样的问题：

fatal: unable to access ‘GitHub - discourse/pups: Simple yaml based bootstrapper for Linux machines · GitHub’: Could not resolve host: github.com

** 引导失败 ** 请向上滚动查看更早的错误信息，可能不止一条。

由于我不是开发者/程序员，仅对 FTP、SSH 和 Linux 命令有有限的了解。我主要是自己搭建论坛，并在过程中学习。

不过，今天我修改了 app.yml 中的 SMTP 信息，然后重新构建时遇到了这个问题。
能否有人指给我一份全面的指南，以解决 Docker 相关的问题？

如果您的服务器无法解析 GitHub，那么您可能遇到了某种 DNS 问题。
