This makes things a little neater when debugging or testing new configurations on the command line.

Tiller and Docker environment variables

After a recent query was posted on the Tiller issue tracker, I thought it might be useful to show a complete example of using Tiller and one of it’s plugins to create a dynamic Docker container. I assume you’re at least somewhat familiar with Tiller. If not, take a quick look through my documentation and other related blog posts.

Tiller v0.0.7 now supports environment variables
