Hi guys,

Trying to use chef tools to build desired docker container.  
I'm following the article :  
[http://docs.opscode.com/containers.html](http://docs.opscode.com/containers.html)  
And my installation attempt of knife-container gem fails with this error:  
ERROR: Could not find a valid gem 'knife-container' (\>= 0) in any repository  
ERROR: Possible alternatives: chef-container, zip-container, knife-softlayer,  
henry-container, knife-config

Is it actually normal and i'm missing something?  
Or this actullay is outdated documentation?

Regards

---

Hi!

The documentation is actually too new as that gem has not been released yet. We are still working out some final bugs. Expect the gem to be released in the near future.

If you like, you can build the development gem manually from our github repo: [GitHub - chef-boneyard/knife-container: DEPRECATED: Container support for Chef's Knife Command](http://github.com/opscode/knife-container)

Thanks,  
Tom
