I am using CUBE format in my arquillian.xml and have something like this but alias does not seem to work, am I missing anything?

tomcat:
  image: tutum/tomcat:8.0
  exposedPorts: [8089/tcp]
  env: [JAVA_OPTS=-Dcom.sun.management.jmxremote.port=8089 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false]
  portBindings: [8080/tcp, 8089/tcp]
  networkMode: automationNetwork*
  await:
  strategy: polling
  cart*:
  image: cicd/my-fake-service:latest
  portBindings: [8080/tcp]
  networks:
  automationNetwork*:
  aliases: cartHost
  await:
  strategy: polling
  slotService*:
  image: cicd/my-fake-service:latest
  portBindings: [8080/tcp]
  networks:
  automationNetwork*:
  aliases: slotHost
  await:
  strategy: polling
  shippngService*:
  image: cicd/my-fake-service:latest
  portBindings: [8080/tcp]
  await:
  strategy: polling
  paymentService*:
  image: cicd/my-fake-service:latest
  portBindings: [8080/tcp]
  await:
  strategy: polling
  </property>
  <property name="clean">true</property>
</extension>

from commandline I am able to run docker command and create alias and connect containers using alias.
