Thanks for your precious support!
I realised that what i was trying to do was hardly possible 
But i’ve learned a lot along the way. I’m using a MIPSBE architecture mikrotik(RB951Ui2Hnd, but was even targetting much cheaper hAP lite), and containers only work on ARM and x86 :facepalm: I was trying to go too fast. I was trying to design a cheap and compact solution that can be easily replicated for that i needed the REST API that came in routeros v7 and the possibility to allow cross origin requests, for wich the the reverse proxy was supposed to be the solution, but then i would need a higher end device, or buy routerOS License4 with ARM based SBC like RaspberryPi and these don’t generally have a good WiFi radio, so would have to invest in that too and will quicly run out of the ideal budget for this solution. I’ll keep searching to find a way out.
There was an interesting discussion about here (http://forum.mikrotik.com/t/container-support-to-mips-architeture/159413/1) about container support for MIPSBE and various use cases, but clearly seems like Mikrotik is not willing to go that route.
Regards.
