Mixin common compose data

I am using NGINX for my stacks - and I have to insert a VIRTUAL_HOST env - is there a way of merging a common compose.yml / config.yml to allow me to specify a standard set of envs (and other stuff)

In the api data for a catalog entry, both the catalog and version have a “templateBase”: “”, key - but I can’t find any documentation on this.

There is not any mechanism to do that…

templateBase is the prefix of the top-level template folder (i.e empty for cattle templates, “mesos” for mesos, “kubernetes” for kubernetes, etc.). It’s just for the UI to select the right set of templates to show for the selected orchestration of the environment.
