anchor.diff:  
   | *docker.ports.idx*
   | Sets a port mapping. For example `<docker.ports.1>jolokia.ports:8080<docker.ports.1>` maps the container port 8080 dynamically to a host port and assigns this host port to the Maven property `${jolokia.port}`. See <<_port-mapping,Port mapping>> for possible mapping options. When creating images images only the right most port is used for exposing the port. For providing multiple port mappings, the index should be count up.
  +See <<list-properties>> for more information about list properties.
   
   | *docker.registry*
   | Registry to use for pushing images.
  
positive.code: ----
  
  The behaviour will now be same as previous example.
  Note that you must explicitly state `<mode>override</mode>`, otherwise it will use the default `only`.
negative.code: | Logging driver options (specified similarly as in `docker.env.VARIABLE`)
  
  | *docker.links.idx*
  | defines a list of links to other containers when starting a container. For example `<docker.links.1>db</docker.links.1>` specifies a link to the image with alias 'db'.
  See <<list-properties>>.
  
  | *docker.maintainer*
  | defines the maintainer's email as used when building an image
