容器初始化后如何连接到docker-compose mysql？

Question

我有一个正在进行的项目，现在我正在尝试使用docker-compose进行构建。 在运行自己的自定义脚本以创建表之前，我以为我可以尝试一下，看看它是否可以建立并且可以连接到它。

我找到了一个适合mysql的docker-compose：

version: "3.8"
services:
  mysql:
    image: mysql:latest
    ports:
      - 3307:3307
    environment:
      MYSQL_ROOT_PASSWORD: SomeRootPassword1!
      MYSQL_USER: someuser
      MYSQL_PASSWORD: Password1!
      MYSQL_DATABASE: wedding

在gitbash中运行docker-compose-up之后，我看到：

问题

现在以上操作已完成（不确定是否所有操作正确）我想我会尝试通过mysql工作台连接到它，但是我得到了以下信息：

我还尝试将绑定地址更改为：

我在做什么错了？

Answer 1

在撰写文件的ports:下，您创建了从localhost:3307到container:3307的转发规则。

虽然您可以选择主机上未使用的任何源端口，但另一方面，您必须点击容器正在侦听的端口：在这种情况下，它将是{ {1}}。

您的docker-compose.yml文件应如下所示：

3306

...那么您应该可以通过version: "3.8" services: mysql: image: mysql:latest ports: - 3307:3306 environment: MYSQL_ROOT_PASSWORD: SomeRootPassword1! MYSQL_USER: someuser MYSQL_PASSWORD: Password1! MYSQL_DATABASE: wedding

进行连接

Answer 2

您需要使用docker内部网络来绑定地址，而不是localhost（如果您不公开端口），则将0.0.0.0替换为host.docker.internal。这应该可以解决问题。
