Question

我尝试使用优秀的latex.comnmodel.org docker容器在nginx-proxy上的vps上解析 502网关错误。我在配置中丢失了，所以我将此问题作为github中的问题进行交叉转换，并在此处寻求帮助。

我的docker0为172.17.0.1，docker -ps命令返回：

我使用和不使用VIRTUAL_PORT选项创建sharelatex图像：

sudo docker run -d -e "VIRTUAL_HOST=latex.comnmodel.org" -e "VIRTUAL_PORT=80" -v ~/sharelatex_data:/var/lib/sharelatex -p 5000:80 --name=sharelatex sharelatex/sharelatex

docker exec pensive_raman grep -vE '^\s*$' /etc/nginx/conf.d/default.conf返回

当我ping latex.comnmodel.org位于我的vps ip 51.255.47.40时：

我尝试连接到pensive_raman（nginx-proxy映像的名称）并ping sharelatex容器172.0.17.5，但没有成功，我的网络配置是否有问题？

我是否需要使用--link的{{1}}选项连接nginx-proxy容器和sharelatex容器？
我在docker run上有两个80端口，可能是问题，我需要在运行sharelatex映像时精确设置ip 0.0.0.0吗？这不干净

网站172.17.0.5返回latex.comnmodel.org，我想念的是这里，这非常令人沮丧:(

更新1：

Documentation表示如果502 bad gateway，命令--icc = false命令包含DROP RULE。似乎情况并非如此，因此icc选项采用默认的真值。

sudo iptables -L -n

Answer 1

检查您是否正在使用--icc=false运行docker守护程序（容器间通信）
