Hi Hari,

I just tried this with an up to date docker install on my mac. My guess is that the node you are running on has an old/limited root certificate bundle and so TLS is failing. Or there is some "man in the middle" type attack going on that is preventing docker from validating the TLS connection to google storage.

I'm going to close this as I'm pretty sure this isn't an issue specific to kuard.
