Question

Docker版本17.03.1-ce，构建c6d412e 操作系统：Ubuntu

我正在尝试从docker容器连接到主机mysql。但是我收到了这个错误。

错误：连接ECONNREFUSED 0.0.0.0:3306

如果我使用mysql容器，我的mysql会变得相同。尝试了127.0.0.1和localhost。

version: '2'

Answer 1

您应该使用主机的IP，而不是使用0.0.0.0,127.0.0.1或localhost。这是因为每个容器都是网络中的单个节点。

或者，如果您可以检查MySQL容器并获取其IP，您也可以使用IP，因为它们位于同一网络上。
