ningyougang opened a new pull request #2662: Add judge condition for invoker deployment
URL: https://github.com/apache/incubator-openwhisk/pull/2662
 
 
   If invokers have been deployed success.
   Then, it will report error when execute `ansible-playbook -i environments/<env> invoker.yml ` again.
   because the invoker0 or invoker1 alreay exist, so below errors will appear.
   ```
   TASK [invoker : start invoker using docker cli] *********************************************************************************************
   ...
   ...
   You have to remove (or rename) that container to be able to reuse that name..\nSee 'docker run --help'.", "stderr_lines": ["docker: Error response from daemon: Conflict. The name \"/invoker0\" is already in use by container 1de4dc7d6ca3234d1b6590061e637c48367f9076766f767ef9271d1848e08620. You have to remove (or rename) that container to be able to reuse that name..", "See 'docker run --help'."], "stdout": "", "stdout_lines": []}
   [FAILED]
   ```
   
   So it is necessary to add the `judge condition` that whether the invoker has been deployed.
