Yeah, so we followed the link toast0 shared to get started:

It took some work to piece together but wasn't too complicated in the end. It's internal code that I can't quickly sanitize or I'd just dump it in a gist :/ Someone on the Elixir Forum might have a template or library handy though.

Other replies are a bit outdated. It got a lot easier in OTP-23 to go without EPMD, https://blog.erlware.org/epmdlessless/ -- if you run with the same port. If not using the same port across nodes then you may want to look at epmdless https://github.com/tsloughter/epmdless

I didn't write this blog, but it looks like it's got the right info: https://www.erlang-solutions.com/blog/erlang-and-elixir-dist...

You can skip to "Let’s use something else" if you've already got a good grasp of the knobs to tune with epmd.

Same. I'm not clustered yet, but I plan on it before EOY and that would be amazing. I think route53 has some internal routing capabilities, but some of the setup looks scary, or am I just being silly?

Not sure if it's helpful but I got clustering working on ECS mostly following this guide: https://towardsaws.com/an-elixir-migration-to-microservices-...

just beware service discovery via DNS in AWS will return up to 8 addresses. so if you have more than 8 nodes you will get a random subsample for each request. depending on how your clustering works this may or may not be a problem. you can use the web api if you need to handle more than 8 hosts.
