The render.com deployment guide is pretty good, and works very nicely for deploying to render.com too!!

Guide is here:

I deploy my charting library sample code and package website more or less using that recipe. Code is here: GitHub - mindok/contex-samples: Sample web application demonstrating contex features · GitHub.

bin folder contains the release script.

The sample app uses web sockets to support liveview pages.

If you don’t need a database, render.com is about $7/month. It’s a little more complex and a few more $/s a month if you need a database or file storage, but still pretty easy and the guides are really good - I have another database-backed app deployed there.

If you want something easy and simple then I think you’d definitely want to look at http://heroku.com/ or gigalixir (as previously mentioned). They both have free tiers which is great for a side project.

I think you’d want to stay away from docker and kubernetes if you’re just getting started.

Been there done that (recently). My two cents:
Go with mix releases and just follow the Phoenix docs (it doesn’t get easier than that).

My experience was that the number of available blog posts and tutorials online made me a little bit confused about what was the “recommended way” to deploy whether the reality of how to do it is way simpler

After you feel comfortable with the basics steps I’ll advise looking into docker or configuring a deployment pipeline.
