 EXAMPLES = '''
-Start one docker container running tomcat in each host of the web group and bind tomcat's listening port to 8080
-on the host:
+Build docker image if required. Path should contains Dockerfile to build image:
 
 - hosts: web
   sudo: yes
   tasks:
-  - name: run tomcat servers
-    docker: image=centos command="service tomcat6 start" ports=:8080
+  - name: check or build image
+    docker_image: path="/path/to/build/dir" name="my/app" state=present
 
-The tomcat server's port is NAT'ed to a dynamic port on the host, but you can determine which port the server was
-mapped to using docker_containers:
+Build new version of image:
 
 - hosts: web
   sudo: yes
   tasks:
-  - name: run tomcat servers
-    docker: image=centos command="service tomcat6 start" ports=8080 count=5
-  - name: Display IP address and port mappings for containers
-    debug: msg={{inventory_hostname}}:{{item.NetworkSettings.Ports['8080/tcp'][0].HostPort}}
-    with_items: docker_containers
+  - name: check or build image
+    docker_image: path="/path/to/build/dir" name="my/app" state=build
 
-Just as in the previous example, but iterates over the list of docker containers with a sequence:
+Remove image from local docker storage:
 
 - hosts: web
   sudo: yes
-  vars:
-    start_containers_count: 5
   tasks:
   - name: run tomcat servers
-    docker: image=centos command="service tomcat6 start" ports=8080 count={{start_containers_count}}
-  - name: Display IP address and port mappings for containers
-    debug: msg={{inventory_hostname}}:{{docker_containers[{{item}}].NetworkSettings.Ports['8080/tcp'][0].HostPort}}"
-    with_sequence: start=0 end={{start_containers_count - 1}}
-
-Stop, remove all of the running tomcat containers and list the exit code from the stopped containers:
+    docker_image: name="my/app" state=absent
 
-- hosts: web
-  sudo: yes
-  tasks:
-  - name: stop tomcat servers
-    docker: image=centos command="service tomcat6 start" state=absent
-  - name: Display return codes from stopped containers
-    debug: msg="Returned {{inventory_hostname}}:{{item}}"
