Automatic deletion

Temporary container images will be automatically removed when the test JVM shuts down. If this is not desired and the image should be retained between tests, pass a stable image name and false flag to the ImageFromDockerfile constructor.

Retaining the image between tests will use Docker's image cache to accelerate subsequent test runs.

By default the no-args constructor will use an image name of the form testcontainers/ + random string:

    public ImageFromDockerfile()
    public ImageFromDockerfile(String dockerImageName)
    public ImageFromDockerfile(String dockerImageName, boolean deleteOnExit)
