 Review comment:
   I have tried it and it worked.
   But we need ugly url encoded due to filters.
   
   ```
   - name: determine if any invokers are running
     uri: url="http://{{ inventory_hostname }}:{{ docker.port }}/containers/json?filters=%7B%22name%22:%5B%22invoker%22%5D%7D" return_content=yes
     register: invokerInfo
   ``` 
   I couldn`t find any option to encode curly braces and brackets.
   
   If possible, we can get rid of annoying ansible warning.
