使用测试容器时如何解决"Can't get Docker image"？

Question

我正在使用测试容器，直到现在它都可以正常工作。我最近更新了 docker 和 IntelliJ，但我不知道这是否是以下问题的原因。

这是我使用的依赖项：

testCompile 'org.testcontainers:testcontainers:1.12.3'
testCompile 'org.testcontainers:oracle-xe:1.12.3'

这是堆栈跟踪：

有谁知道如何解决这个问题？

提前致谢。

Answer 1

问题是由新的 docker 版本引起的。如果您将 docker 更新为 2.4.0，那么您可以尝试几个选项。

在 docker 首选项中关闭“使用 gRPC FUSE 进行文件共享”选项。
将测试容器更新为 1.15.0-rc2
将 docker 降级为 2。3.x

我尝试了第一个选项，它对我有用。

我用的是mac。不知道其他平台有没有类似的问题
