Question

我有一个junit测试，必须启动一个docker容器。这是我使用的代码

 @ClassRule
public static ContainerDslRule mysql = new ContainerDslRule(TestConfigConstants.DOCKER_IMAGE)
        .withPortBinding(TestConfigConstants.PORT)
        .withEnvironment("MYSQL_ROOT_PASSWORD", TestConfigConstants.PASSWORD,
                "MYSQL_DATABASE", TestConfigConstants.DB,
                "MYSQL_USER", TestConfigConstants.USERNAME,
                "MYSQL_PASSWORD", TestConfigConstants.PASSWORD);

当我在安装了docker工具箱的Windows 7 pc上开始测试时，一切正常。但是，当我在Windows 10 PC上启动时，我有以下异常

有什么想法吗？

Answer 1

我认为有与docker机器有关的东西，但现在还不确定问题，你在那台机器上安装了多少台机？如果它只有一个，你可以尝试手动启动它（即docker-machine start dev）

如果它有效，那么当docker-machine尚未启动时会出现错误。
