ningyougang opened a new pull request #2585: Add the image filter when get invoker info
URL: https://github.com/apache/incubator-openwhisk/pull/2585
 
 
   The `nodejs6action` container is created by invoker which test the invoker whether worked well, sometimes, 
   its name may has `invoker` substring, for example as below
   ```
   37d73d962120        whisk/nodejs6action:latest   "/bin/sh -c 'node --e"   13 minutes ago      Up 13 minutes                                                                          wsk0_3_whisksystem_invokerHealthTestAction0
   2581c86d6ada        whisk/invoker:latest         "/bin/sh -c 'exec /in"   13 minutes ago      Up 13 minutes       0.0.0.0:12001->8080/tcp                                            invoker0
   ```
   If above situation happens, below ansible task's revokerInfo's length will be greater than 1
   ```
   - name: get running invoker information
     uri: url="http://{{ inventory_hostname }}:{{ docker.port }}/containers/json?filters={{ '{"name":[ "invoker" ],"ancestor":[ "invoker" ]}' | urlencode }}" return_content=yes
     register: invokerInfo
   ```
   then, below ansible task will be failed
   ```
   TASK [invoker : determine if more than one invoker is running] ******************************************************************************
   Monday 07 August 2017  22:15:36 -0400 (0:00:00.314)       0:00:02.154 ********* 
   fatal: [10.34.135.216]: FAILED! => {"changed": false, "failed": true, "msg": "more than one invoker is running"}
   ```
   
   How to solve this problem, i think the best way is `add image filter` to search exactly
