I have gone through several methods of deployments, some are still in use today. The easiest and most robust approach is actually writing scripts that executes Distillery on a build server and then manually “deploying” the compiled binary to my production servers. This works for low frequency deployments but it’ starting to hurt when you need more than one deployment per day.
Dockerised app is perhaps the easiest to automate deployment, but they came with some caveats, for example, I couldn’t do hot-code upgrades with them.
Edeliver has its drawbacks, but with a little tweaking, it simply works 99% of the time.
Honestly I don’t mind the bash scripts, but with Elixir we could probably build better error handling mechanism.
