LDAP服务器关闭“多阶段Docker构建”

时间：2019-11-18 11:53:29

标签： docker flask ldap

我正在使用官方python映像“ python：3.7-buster”，nginx，supervisor和uwsgi为我的应用构建多阶段docker。 映像构建成功，并且我可以检查不使用ldap的路由，但使用的路由会出现此错误：ldap.SERVER_DOWN: {'desc': "Can't contact LDAP server", 'errno': 107, 'info': 'Transport endpoint is not connected'}"。 该应用程序在docker外部运行良好。

我的dockerfile：

1 个答案:

答案 0 :(得分：0)

所以我解决了这个问题，它是ldap应用程序配置上的主机，需要将其更改为：host.docker.internal
