integrationTests requires "hidden" quay.io/testcontainers/ryuk docker image

[Pierrotws]

Hi,

testing to build heroic for the first time, integrationTests failed. Due to a missing docker image.

com.spotify.heroic.PubSubConsumerIT > consumeOneMessage FAILED
    org.testcontainers.containers.ContainerLaunchException: Container startup failed
        Caused by:
        org.testcontainers.containers.ContainerFetchException: Can't get Docker image: RemoteDockerImage(imageNameFuture=java.util.concurrent.CompletableFuture@5f9adb66[Completed normally], imagePullPolicy=DefaultPullPolicy(), dockerClient=LazyDockerClient.INSTANCE)

            Caused by:
            com.github.dockerjava.api.exception.NotFoundException: {"message":"No such image: quay.io/testcontainers/ryuk:0.2.3"}

This image is not specified in the code so I guess this is a requirement of a dependency. Other docker images that are explicitly mentioned in the code as bigtruedata/gcloud-pubsub-emulator were automatically pulled as seen in the test just before the failing one:

com.spotify.heroic.PubSubConsumerIT > consumeOneMessage STANDARD_OUT

Build works fine just after manual pulling of image quay.io/testcontainers/ryuk:0.2.3

@Pierrotws there was a regression caused by the recent Docker release, and it is recommended to update Testcontainers to the latest version to fix the pulling issue. I hope this information helps the maintainers :)
