What is the best way to use template composition with heat interface ?
Heat interface doesn't allow to load severals files. What is the best way to expose a composed template ? At now, I use http server.
Using the dashboard or the CLI ?
Using the dashboard I upload the other yaml files to a web server (GitHub, in my case) and then use the URL to call them. Using the CLI is easier, you only need to put the files in the same directory of the main yaml.
