SSH 到 docker 容器不起作用

我正在 Ubuntu 服务器中运行 Discourse 论坛软件容器，我能够使用该命令登录到容器。

sudo docker exec -it 应用程序 bash

然后我为 root 用户设置了密码，但是 ssh 没有按预期工作，总是得到错误的密码。

请指教。

答案1

该问题现已解决。

似乎是 Discourse SSH 容器配置的问题，

在 /etc/ssh/sshd_config 中

PermitRootLogin without-password

我已将其更改为

PermitRootLogin yes

#PermitRootLogin without-password

这解决了问题。

答案2

您应该使用代码标记来粘贴到日志文件中，但据我所知：

sshd[32711]: debug1: PAM: password authentication
failed for root: Authentication failure Aug 26 20:32:29

似乎相关。您确定您的 docker 镜像的 root 用户使用了正确的密码吗？

另外，您是否重新启动了 sshd 服务（在 docker 映像中）以便重新加载 sshd_config ？
