What's the best/ easiest/ most reliable way to get a selfhosted install of ElasticSearch up and running somewhere?

Whilst we wait for ElasticSearch to be added as a Cloudron addon, what's the best/ easiest/ most reliable way to selfhost an install of it somewhere?

I'd like to connect at least one of the various instances of Mastodon 4.2 I'm running to it.

Thanks in advance for your suggestions Cloudron hive mind!
