mongodb - Docker无法连接到mongodb云

Question

无法使用来自Docker的mongoshell连接到mongodb云。
在Opensuse 42.3 linux平台上工作。 IP_FORWARD已启用，防火墙已禁用。

./mongodbshell/bin/mongo  "mongodb+srv://cluster0-ry2xn.mongodb.net/test" --username

但是，它在外部docker上运行良好。下面给出的是我的docker环境信息。

这与不设置基于SSL / TLS的身份验证有关吗？任何帮助将不胜感激。

IP_FORWARD还不够，您需要在这些不同网络之间使用masquerade(或NAT)。如果网络之间存在一个公用网关，则也可以使用静态路由。
