Container.create missing cmd parameter?

[jeffgus]

I tried to run a simple test, but it fails because Container.create is missing the cmd parameter.

This did not work:
container = Docker::Container.create('Image' => image.id, 'name' => container_name)

This works:
container = Docker::Container.create('Cmd' => :command, 'Image' => image.id, 'name' => container_name)

Get same issue with CentOS docker images, which supplied without default command:
Docker::Error::ServerError: No command specified

Can you guys please put some default command there (like /bin/bash)?

I get
Docker::Error::ServerError
--------------------------
No command specified
as well.

If I edit line 200 of /opt/chef/embedded/lib/ruby/gems/2.1.0/gems/chef-provisioning-docker-0.5.2/lib/chef/provisioning/docker_driver/driver.rb to change
container = Docker::Container.create('Image' => image.id, 'name' => container_name)
to
container = Docker::Container.create('Image' => image.id, 'name' => container_name, 'Cmd' => docker_options[:command])

then it works.
