I stop with this discussion, it's useless. If you want to promote environment variables and de docker compose file it's very easy for you to add some examples on the site. The https://www.traccar.org/reverse-geocoding/ page doesn't even have environment variables examples. It's very easy for you to add the same parameters as a docker compose example.
Thanks.
Hmm when I see terminology I'm not familiar with I generally look it up rather than yell at the guy making free software. That's just me though.
But you see an example of how it works, right? Even if you don't know the terminology, surely you can see what the example is showing and you see the same thing working in your case.
