I am sorry to hear that you had bad experiences while deploying Elixir. To avoid having others running into the same bad experiences, I would like to point out to some resources and recent improvements in the area for those interested in deploying Elixir.
There are mostly two ways to deploy Elixir. One is the provisioned approach: you install Erlang/Elixir (or you assume it is installed in the machine), then you fetch your project source code, fetch deps, compile them and run your project (in the same way you would run it locally).
The other approach is via releases. A release is a way to package the Erlang VM, Elixir and all of your application code into something you can dropped into production. The downside is that you need to match the target OS and architecture but there are many documented approaches to do so. Today the main tool f

or performing releases is Distillery and it has great documentation covering AWS, Docker, etc: https://hexdocs.pm/distillery/home.html
In Elixir v1.9, coming out this July, we are incorporating releases as part of the language. You can read more about it in our documentation for master: https://hexdocs.pm/mix/master/Mix.Tasks.Release.html
If you are using a PaaS such as Heroku, it is likely there is already tooling that will take care of it for you, such as the Heroku Elixir buildpack: https://github.com/HashNuke/heroku-buildpack-elixir. There is also Gigalixir, a PaaS specific to Erlang/Elixir: https://gigalixir.com/
Finally, if you want a more structured resource, there is also the Adopting Elixir book (disclaimer! I am one of the authors): https://pragprog.com/book/tvmelixir/adopting-elixir - One third of the book is about production concerns, covering deployment, performance, metrics, monitoring, etc.
If none of this works, you can always reach out to the community in elixirforum.com. I assure you there are more than 2 developers that know about deployment :) and if you still feel like none of the replies about deployment there have been satisfactory, feel free to add me to the conversation there.
> And you're definitely not going to write CLI tools in Elixir (it straight doesn't work with escript in the first place).
I do not understand this comment as Elixir works with escripts just fine. You can build an escript for your project by simply calling `mix escript.build`. This has been available since v1.0 (https://github.com/elixir-lang/elixir/blob/v1.0.0/lib/mix/li...). You can even install escripts directly from Hex (our package manager) since Elixir v1.4 (2.5 years old).
