@aanand This is an implementation of what you suggested in # 1 of your comment on #227. Just wanted to make sure you saw it. |

Yes! Was trying it out earlier - looks good. I'll merge it tomorrow. On Tue, Jul 8, 2014 at 10:09 PM, Ryan Brainard notifications@github.com

For parity with the Docker CLI, allow environment variables without values to be automatically resolved to their values on the host.
If someone defines an
environmentas alist, this also converts it to adictso the above resolution works as expected. Definingenvironmentasdictis canonical, but using alistalready worked, so this conversion supports backward compatibility.docker-py resolves
environmentwith a value ofNoneto the string'None', which is not what someone would want if the value could not be found in the host's environment. This resolves that case to empty string, which is how Docker CLI also handles this situation.Fixes #277
