'iotedgedev build' produces error

[scout208]

Trying to run iotedgedev build in my solution created from iotedgedev init Sample produces the following error messages:

ERROR: ('Could not connect to Docker daemon. Please make sure Docker daemon is running and accessible', DockerException("Error while fetching server API version: ('Connection aborted.', PermissionError(13, 'Permission denied'))"))

Also,

DeprecationWarning: The command 'build' is deprecated.

See the output screenshot below.

There was no issue about the deprecation warning so I created #633 about that. It's a known problem but doesn't look like it's been fixed yet.
