Another super-quick update : There’s now a Gitter chatroom for Tiller. Feel free to drop by for help and chat with other users!
I recently released Tiller 0.7.6 with a new feature for the environment_json plugin. This can be used to provide dynamic configuration for Docker containers, using JSON in an environment variable. I previously posted a complete example of how you’d make use of this. However, most Tiller plugins provide values as “global” sources, which will be over-ridden by local, template-specific values.
