I am wondering is it possible to load not only appconfig.json from spring config server but other files. For example i have got a templates in .html format. Can I somehow get them from spring server along with appsettings file? Probably steeltoe knows how to do that?
Steeltoe does provide a configuration provider for Spring Cloud Config Server that will allow you to map configuration values from any supported file format into key-value pairs, and there are several strategies for layering multiple configuration files but I don't think there would be any support for .html files.
If you're looking for a way to use version-controlled templates, why not read from a git repo directly rather than putting config server in the middle?
