Arquillian cube can't retrieve image id from docker server

[BrunoGilbertCrane]

I try to run some tests with arquillian-cube-containerless 1.0.0.Alpha3.

I got the exception : org.arquillian.cube.spi.CubeControlException: Could not create mycube.
...
Caused by: java.lang.IllegalStateException: Docker server has not provided an imageId for image build from src/test/resources/docker/mondrian. Response from the server was:
Step 0 : FROM ubuntu:12.04 ---> f959d044ebdfStep 1 : MAINTAINER ......Successfully built bc7b77133064

As you can see the docker was build but the image id was not retrieved by DockerClientExecutor .buildImage().

I run this test on a ubuntu 12.04.

Using regular expression it is possible to resolve this issue in DockerClientExecutor class

private static final Pattern IMAGEID_PATTERN = Pattern.compile(".*Successfully built\s(\p{XDigit}+)");

Matcher m = IMAGEID_PATTERN.matcher(fullLog);
String imageId = null;
if (m.find()) {
imageId = m.group(1);
}
return imageId;

Strange that this happens just now. Probably it is something related with a docker version that has changed the way the instructions are executed or notified. Yes probably we will need to change to the regexp yo unoticed here.

BTW because of #67 now the image id will be used everywhere internally so we will not need to do the matcher approach to get the id because the DockerClient is going to return too.

Thanks for opening the issue, I am going to add your pattern expression to cover more cases.
