当我想从 pgadmin 添加服务器时，出现以下错误。 timeout expired error。 我该如何解决这个问题？ 谢谢...
【问题讨论】：
你能提供docker-compose.yml或者你是如何开始这一切的
@Jean-JacquesMOIROUX 这是我所有的 docker-compose.yml 内容：nkwall.ir/docker-compose.yml
【参考方案1】：
语法在环境中很奇怪。创建一个包含您的秘密的 .env 文件，然后从 docker-compose 加载它
.env

【讨论】：
我尝试了类似的方法，但使用./config.env 而不是.env。我收到有关未设置变量的错误。 It turns out，一般来说env_file:只设置runtime环境中的变量（在容器中），所以不能用于在yaml文件中填写$my_var。 .env 是特殊的，在解析 yaml 文件之前被读取和设置。 （实际上它甚至根本不需要env_file: 条目）。这就是为什么它可以用来填充$my_var以上是关于在 docker 的 pgadmin 中添加新的 postgres 服务器的主要内容，如果未能解决你的问题，请参考以下文章
docker postgres pgadmin 本地连接
