edit: my experience has been with Erlang deployments, I don't yet know what the landscape is like for Elixir - at least the first part of my comment below can be disregarded. I would assume it's similar to deploying an erlang application, but I don't know for sure. I think the second part is still possible, since if it can be done for Erlang it can be done for Elixir. -- Original post -- I haven't found production deployments to be particularly painful, I'd be interested to hear what kind of troubles you've run into. Runtime configuration is definitely possible - you can deploy configuration files with your application and determine which one you want to load. It's not built-in, but it's a few lines of code to do it manually. You can also always use environment variables, which is arguably a better approach.
