Docker: connection between golang webapp and postgres server refused

问题

我无法将我的Postgres容器与我的golang webapp容器连接起来。

我得到了以下错误:

panic: dial tcp [::1]:5432: getsockopt: connection refused

我的docker compose文件:

http://pastebin.com/5LQfn3gy

有什么办法可以解决这个问题吗?

英文:

I can't connect my Postgres container with my golang webapp container.

i got following error:

panic: dial tcp [::1]:5432: getsockopt: connection refused

My docker compose file:

http://pastebin.com/5LQfn3gy

Any idea how i can fix that?

由于您指定的IP地址与主机相关,而不是Docker环境,而且您也在Docker中运行应用程序,所以可以省略IP地址部分:

ports:
  - 5432:5432

因此,您只需要将Postgres的别名和端口传递给您的Go应用程序(可以作为环境变量或标志)。

英文:

Since the IP you specified relates to your host and not your docker environment and you're running your app inside docker too, just omit the IP:

ports:
  -5432:5432

So you'd just need to pass the Postgres alias, followed by its port to your go app (either as an env var or a flag).
