testcontainers - 无法连接到 Ryuk？

Question

您好，我正在尝试从我的单元测试类中启动一个测试容器。

在我的测试课上，我正在使用以下内容

   @Container
    private static GenericContainer<?> testContainer =  new GenericContainer<>(TEST_IMAGE)
            .withCommand("sleep infinity")
//            .withLogConsumer(LOG_CONSUMER)
            .withNetwork(dockerNetwork).withNetworkAliases(TESTCONTAINER_NETWORK_ALIAS);

但是当我运行我的测试时，我得到下面的错误

SEVERE: Caught exception while closing extension context: org.junit.jupiter.engine.descriptor.ClassExtensionContext@495ee280

感谢任何帮助谢谢

java.lang.IllegalStateException: Could not connect to Ryuk at

这可能是由于运行 docker 的(虚拟机)环境管理的磁盘空间不足。如果是这样，您需要清理并回收一些空间。

回收磁盘空间:

 docker system prune

如果在 Windows 上运行，您可能需要重新启动。

我使用 wsl 并且可以确认 wsl --shutdown 是不够的，需要重新启动。
