Hi @Fancy,
Yes, using docker in this way poses a challenge when using it from a different device. The only way I really know of to accomplish this is to somehow convince your DNS provider to add entries for the ziti-controller and ziti-router. Personally, I run a “pi hole” (https://pi-hole.net/) so I can add entries to my name server easily. If you can’t do that, it really does become difficult.
We don’t really have any quickstarts or guides to help with this situation at this time. I filed an issue to track it and hopefully we’ll add it here how-to use docker with local DNS · Issue #402 · openziti/ziti-doc · GitHub
Basically, the docker containers need to use a configuration file that uses the computer’s hostname/fqdn as the ‘advertised’ address to clients so that your android device would be pointed to a known address.
It’s doable, it’s just not something we have ready to try out with doc and how-to do it.
