<p dir="auto">I haven't seen anywhere in the kubernetes documentation that shows how to use variables (either specified command line, or by importing all declared environment variables) in my yaml configuration files.  As I'm getting started with google container engine, it's definitely something I'm already wishing for.<br>
With things as they currently are, I either have to generate the files myself, or maintain multiple copies of similar configuration files (usually by environment).</p>
<p dir="auto">Apologies in advance if this is a duplicate feature request.  I couldn't get a clear idea as to whether this is already underway.</p>
