@nsmith- Looks like the error while bringing a Ceph cluster up is very transient and it's a little difficult to predict the actual cause with almost no good answers to that on the internet.

So, I added a retry script to try the docker run 3 times or fail silently if the error happens all three times in a row, which I think will not be the case, the error being very rare. But this patch will do the job for now. Thanks .

I'd say if it fails three times in a row let it throw and error so we at least look at it. If there's a real problem and we can't see it, then why test?

Yeah, you are right. Let me fix
