Docker無法連接到mongodb雲

Question

無法使用來自Docker的mongoshell連接到mongodb雲。 在Opensuse 42.3 linux平台上工作。 IP_FORWARD已啟用，防火牆已禁用。

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

但是，它在外部docker上運行良好。 下面給出的是我的docker環境信息。

這與不設置基於SSL / TLS的身份驗證有關嗎？ 任何幫助將不勝感激。

Answer 1

IP_FORWARD是不夠的，您需要在這些不同的網絡之間偽裝 （或NAT）。 如果網絡之間存在一個公用網關，則也可以使用靜態路由。

Answer 2

mongo不支持Kali linux發行版。

因此，需要驗證/ usr / bin / mongo --version是否不與輸出中提到的openssl一起返回。 然后，在這種情況下，請卸載所有現有的mongodb工具，服務器和客戶端。

然后根據所使用的Kali linux發行版，使用為debian 7/8平台構建的mongo客戶端重新安裝。 （在我的情況下是debian版本8）

這就解決了在docker上使用ssl運行mongo客戶端的問題：

apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5

echo "deb http://repo.mongodb.org/apt/debian jessie/mongodb-org/3.6 main" |  tee /etc/apt/sources.list.d/mongodb-org-3.6.list

apt-get update

對於包含服務器的完整mongodb安裝，請按照以下說明運行：

apt-get install -y mongodb-org=3.6.2 mongodb-org-server=3.6.2 mongodb-org-shell=3.6.2 mongodb-org-mongos=3.6.2 mongodb-org-tools=3.6.2

僅安裝特定於版本的mongo客戶端和工具：

   apt-get install -y mongodb-org-shell=3.6.2 mongodb-org-tools=3.6.2

僅安裝默認的mongo客戶端和工具：

   apt-get install -y mongodb-org-shell mongodb-org-tools

我在docker上的mongo輸出-kali linux映像現在顯示已配置的ssl：
