Hi all,

I tried to go through the new redis example at the quickstart guide [1],
but was not able to go through. I was blocked by connecting to the redis
slave container:

*$ docker exec -i -t $REDIS_ID redis-cli*
*Could not connect to Redis at 127.0.0.1:6379 <http://127.0.0.1:6379>:
Connection refused*

Here is the container log:

*$ docker logs $REDIS_ID*
*Error: Server closed the connection*
*Failed to find master.*

It looks like the redis master disappeared at some point. I tried to check
the status in about every one minute. Below is the output.

*$ kubectl get pod*

Is anyone able to reproduce the problem above? If yes, I am going to file a
bug.

Thanks,
